What Is The Difference Between Dead End Filtration And Cross Flow Filtration?

Ceramic membrane manufactured by JIUWU HI-TECH is used for liquids separation in a cross-flow filtration way, which is different from dead-end filtration. There are discussed in the following contents.

1. Dead End Filtration
1.1 Dead End Filtration Definition
Dead end filtration means the fluids flow is vertical to the filter surface, and the retained particles rapidly solidify on the surface of the filter to form a so-called filter cake. The pores of the filter are clogged by the filter cake, and the filtration performance is greatly reduced in a short period of time.

1.2 Dead End Filtration System
In the dead end filtration system, it only needs to overcome the membrane resistance. So, an ordinary laboratory vacuum pump or booster pump can provide enough energy to achieve the required flow rate of the microfiltration. However, with the increase of time, the accumulation of particles on the membrane surface also increases, and the filtration resistance decreases the membrane penetration rate. Therefore, the dead-end filtration is intermittent, and it is necessary to periodically stop and clean the contaminated layer on the membrane surface or replace the membrane.

1.3 Advantages of Dead End Filtration
With its own special advantages, the dead end filtration has been used most commonly for laboratory and medical filtration.
(1)The dead end filtration operation is simple and suitable for small-scale occasions;
(2)The dead end filtration has an advantage of high product recovery;

In addition, the dead end filtration is usually used for materials with a solid content of less than 0.1%.

2. Cross Flow Membrane Filtration
2.1 Cross Flow Filtration Definition
Cross-flow filtration means turbulence will happen on the surface of the membrane. Therefore, it allows the filtered material to form a filter cake on the filtering surface and keep the flow constant.

2.2 Cross Flow Filtration System
The cross flow filtration is a kind of tangential flow filtration, which has been used widely in industry around the globe. In the cross flow filtration system, the solution to be filtered is pushed through the pores of the filter membrane by pressure. Because the liquid flow rate is very fast, so the filter pores of the filter membrane will not be blocked. The pore size of the filter membrane determines whether the nature of the filter membrane is microfiltration or ultrafiltration.

2.3 Advantages of Cross Flow Membrane Filtration
Compared with the dead end filtration, the cross flow filtration system has its own special advantages as follows:
(1)There is no need to add filter aid;
(2)It has simple and compact system structure;
(3)It is reusable after backwashing;
(4)The hollow fiber mold stack can be replaced to produce different products;
(5)It is easy to operate.

In conclusion, cross flow can remove build up from the surface of the membrane. So, the permeate flux does not drop as fast when compared to dead end filtration. Cross flow technology also provides the benefit of an improved membrane lifespan by helping to prevent irreversible fouling.

UF Membrane Technology(2024年)

jiuwu — 2024-04-10T11:05:37+0900

https://www.jiuwumembrane.com/uf-membrane-technology.html

Ultrafiltration (UF) is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of the ultrafiltration membrane is in the range of 0.01μm ~ 0.05μm, suitable for the separation, concentration and purification of macromolecules and small molecules.

Ultrafiltration membranes(UF) can separate substances with different characteristics from the solution, thereby achieving the goal of purification. The main characteristics of ultrafiltration membrane(UF) are
A. The separation and purification of macromolecules and micromolecules can be realized at room temperature, instead of the traditional process.
B. Low operating pressure, low investment cost and low energy consumption.

Application of Ceramic ultrafiltration Membrane

Jiuwu Hi-tech provides ultrafiltration membrane technology. UF technology can be used to remove particulates and macromolecules from raw water to produce potable water. It has been used to replace the existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems used in water treatment plants or as stand-alone systems in isolated areas with a growing population.

When treating water containing highly suspended solids, primary (screening, flotation and filtration) and some secondary treatments are often used as a pretreatment stage to incorporate ultrafiltration into the process.

When water recovery is simple, very little processing is often required. However, when more in-depth processing is required, industry standard procedures include the use of UF membrane technology, which means removing the physical solids from the water by passing them through a semipermeable membrane. With ultrafiltration, the solids are primarily captured by the filter and discarded.

Circulating water can also be used in a variety of industrial applications including water supply to boilers or cooling towers, pH control, cleaning equipment, hard beds and vehicles, fire fighting, rinsing or process water for manufacturing industrial lines, toilet flushing, dust control, construction activities Mix with concrete.

Ceramic membrane filtration system is often used to pre-treat surface water, seawater and bioprocessed municipal water upstream of reverse osmosis plants.

Industries that consume large amounts of water or discharge highly toxic wastewater may use ultrafiltration to recover water.

These include chemicals, steel, plastics and resins, paper and pulp, pharmaceutical and food and beverage industries, including soft drinks and canned foods, and electricity, water and wastewater treatment plants.

Ultrafiltration is used to recycle flow or add value to later products and more. In many cases ultrafiltration (UF) is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process. Ultrafiltration is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.

Features of Ultrafiltration Membrane

Ultrafiltration processes are preferred over traditional treatment methods for the following reasons:
No chemicals required (aside from cleaning)
Constant product quality regardless of feed quality
Compact plant size
Capable of exceeding regulatory standards of water quality, achieving 90-100% pathogen removal.

RO Membrane Technology(2024年)

jiuwu — 2024-04-10T11:05:12+0900

https://www.jiuwumembrane.com/ro-membrane-technology.html

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.

RO Membrane Technology is one of the most powerful tools to solve the world water crisis. We have rich experiences in RO technology applied in water &waster treatment .Desalination using RO technology can be achieved by removing salt from seawater. The combination of UF and RO technology in sea water desalination can be customized according to different capacity.

In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

The reverse osmosis membrane technology can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes) but should allow smaller components of the solution (such as solvent molecules) to pass freely.

Advantages of reverse osmosis membrane technology
1. Removes nonionic impurities and dissoved solids (i.e.organics,silica,bacteria)
2. Reduction of hazardous chemical storage and handling associated with ion exchange
3. Reduces loading on ion exchange systems:
Extends run period
Extends resin life
Reductes operating costs

jiuwu — 2024-04-10T11:03:55+0900

https://www.jiuwumembrane.com/mf-membrane-technology.html

Microfiltration (commonly abbreviated to MF) is a type of physical filtration process where a contaminated fluid is passed through a special pore-sized membrane to separate microorganisms and suspended particles from process liquid. MF membrane is commonly used in conjunction with various other separation processes such as ultrafiltration and reverse osmosis to provide a product stream which is free of undesired contaminants.

Microfiltration membranes(MF)can trap particles between 0.1 and 1 micron. MF allow macromolecules and soluble solids (inorganic salts) to pass through, but will trap suspended solids, bacteria, and high molecular weight colloids. The main industrial application of MF is to
1) remove bacteria and other particles in water;
2) remove bacteria in various solutions such as interstitial fluid, antibiotics, serum, and plasma proteins;
3) remove suspended solids, microorganisms and odor impurities in foods such as beverages, alcohol, soy sauce and vinegar.

MF usually serves as a pre-treatment for other ceramic membrane separation processes such as ultrafiltration, and a post-treatment for granular media filtration. The typical particle size used for microfiltration ranges from about 0.1 to 10 µm.In terms of approximate molecular weight these membranes can separate macromolecules of molecular weights generally less than 100,000 g/mol.

jiuwu — 2024-04-10T11:03:24+0900

https://www.jiuwumembrane.com/gold-prize-patent-of-jiuwu-hi-tech-solves-the-prob.html

Energy crisis and environmental crisis are two major problems faced by human society. Reducing fossil energy consumption and increasing the development and utilization of new energy are effective ways to solve these two crises.

Our government has formulated a series of new energy policies to promote industrial upgrading and ensure national energy security, and power energy storage technology is the key link of the new energy strategy. In industry, energy storage technology, as an important supporting technology to integrate transportation and energy in the future, will show value in more application scenarios, and it will also become an essential part of the energy field in China. As the key application of electric energy storage technology, automotive power lithium battery has made remarkable technological progress and industrial achievements in recent years. Lithium is an indispensable basic material for vehicle power lithium batteries. Most of the basic lithium salts for batteries in China are extracted from imported lithium ores. However, China is actually a country rich in lithium resources, with proven reserves of up to 5.4 million tons, but about 85% of lithium is found in Salt Lake Brines distributed in the Qinghai-Tibet Plateau. In our country, the magnesium-lithium ratio of salt lake brine is generally too high, the extraction is difficult and the production cost is high. The technical bottleneck of lithium extraction from salt lake brine with high magnesium-lithium ratio has long restricted the development of lithium resource industry in our country.

New Energy Vehicles

The invention patent of Jiangsu Jiuwu Hi-tech Co., LTD, "A process and device for extracting battery-grade lithium from brine" is useful to solve the problem of extracting lithium from brine of salt lake with high Mg-Li ratio. The invention has just won the Gold Prize of "Patent Award for Membrane Industry" awarded by China Membrane Industry Association, and has been unanimously recognized by relevant experts.

Patent Gold Award of Jiuwu Hi-tech

The patented technology is to add adsorbent to the brine to absorb lithium ion, and use ceramic membrane filter to separate the adsorbent from the brine. The separated adsorbent is washed and desorbed to transfer lithium ion to the desorption solution. The impurity magnesium ion in the desorption solution is removed by nanofiltration membrane system and ion exchange resin tower. The purified desorption solution is concentrated by reverse osmosis membrane and then concentrated by DTRO membrane or electrodialysis. After evaporation, the concentrate is precipitated by adding refiner to precipitate impurity ions in the process of concentration. The impurity precipitation is separated and removed by ceramic membrane filters. The filtrate is reacted with soda solution to form lithium carbonate. Finally, the lithium carbonate product of battery grade can be obtained by centrifugal drying after washing the lithium carbonate with ceramic membrane. The invention solves the problems of long time-consuming, low concentration of lithium chloride, low yield, high consumption of chemical reagents and low purity of products in the traditional process of extracting lithium from brine, and provides an ideal technical route for large-scale low-cost production of high-quality lithium carbonate with high magnesium-lithium ratio to Salt Lake brine.

This technology uses the high performance lithium adsorbent developed by Jiangsu Jiuwu Hi tech Co., Ltd. It is suitable for chloride salt lakes with various Mg/Li ratios. Compared with traditional adsorption processes, it can save 50% of adsorbents and project construction investment. The technology can also be used to extract lithium from raw halogen, and the lithium extraction capacity can be quickly obtained without restriction of salt field construction before the lithium extraction section is mentioned to precipitate sodium and potassium. The application of this patent will make outstanding contribution to the development of new energy industry in China.

Technological Process

Jiangsu Jiuwu Hi-tech Co., Ltd has long been committed to the development and application of the overall solution for lithium extraction from salt lakes. It has high-performance lithium adsorbent preparation technology and a variety of lithium extraction process kits in salt lakes. It has applied for eight patents and has established a 10,000-ton/year lithium magnesium-lithium carbonate separation industrialization project. The project's lithium carbonate products can be used in the production of about 250,000 new energy vehicles, and fuel vehicles can help reduce carbon dioxide emissions by about 800,000 tons per year over the same period.

Membrane Integration Equipment

I have long aspired to reach for the clouds and my heart longs for the sky. Jiangsu Jiuwu Hi-tech Co., Ltd has accumulated abundant experience in the application of lithium extraction technology of salt lakes, and has realized many technological innovations in the field of lithium extraction of salt lakes.

WINE AND LESS
China membrane crossflow filtration is becoming the unique alternative to kieselguhr filters in wine industry with the developments in environmental and health regulations.

Membrane crossflow filtration is widely used in wine membrane filter system for wine filtration, especially as the red wine filter. It can also be used for cross flow filtration beer. Now, the membrane crossflow filtration technology potential for energy-efficiency has made it a viable technique for the clarification of wine and other beverages.

Crossflow filtration uses a selectively porous ceramic membrane that filters a liquid in order to purify or clarify it. The quality of the filtration is constant over time because the fouling is reduced because the filtering is made without any change of state of the filtered element, and never gets distorted. Membrane crossflow filtration is one of the environmentally-friendly beer membrane filtration systems. During the filtration, no filter aid is used. In one step, crossflow filtration clarifies the wine, giving it a clear appearance and making the wine microbiologically stable. So it has very strong advantages in simplifying the steps before bottling and reducing or eliminating the need for some consumables.

Advantages:
Stable filtrate quality
Maximum guarantee the sensory properties of the wine
Optimized process
No filter aids required
High yield
Reduced filtration costs & product losses
Smart, compact, small footprint

The wastewater containing indigo is characterized by a moderate amount of chemical oxygen demand (COD), pH, suspended solids, dissolved solids and a dark blue color, due to the presence of the dye not fixed to the fiber during the dyeing process.

JIU WU HI-TECH utilizes the unique integrated membrane systems for dye wastewater treatment, which recover the insoluble indigo dye, the production of a secondary commercial product from the waste stream through a by-product synergy process offers an attractive alternative to discharging the untreated effluent into municipal treatment plants or the environment.

WASHING EFFLUENTS
Washing is a finishing process applied to fibres, yarns, and fabrics.

Washing is normally carried out in hot water (40-100°C) in the presence of wetting agent and detergent. The detergent emulsifies the mineral oils and disperses the undissolved pigments. The choice of the surfactants may vary also depending on the type of fibre. Mixtures of anionic and non-ionic surfactants are commonly used. An important factor in the selection of a surfactant is its effectiveness in strongly alkaline conditions.

Washing effluents are mainly composed of soap, grease, synthetic detergents, detergents and a small amount of bacteria, coliform bacteria, viruses, and other harmful substances, has become an important source of water pollution.

After washing effluents are discharged into natural water, dissolved oxygen is consumed and slightly toxic to aquatic organisms, which can cause fish malformation and eutrophication caused by phosphate solvent.

Primary Brine Purification(2024年)

jiuwu — 2024-02-27T10:48:11+0900

https://www.jiuwumembrane.com/application/primary-brine-purification.html

Ceramic Membrane Brine Purification Solution (hereinafter called CBS Process) is a well- proven a well- proven brine purification process for brine water treatment, which can guarantee to offer high quality, stable and reliable primary brine for a long-term and is also an advanced process option for chlor-alkali companies.

CBS combines the characteristics of inorganic materials and the use of efficient "cross-flow" filtration which has greater advantages over other purification technologies.

CBS process can also be used for bittern vacuum salt making and the quality of solid salt produced is higher than that of clarification process which can be used as high-quality edible salt or chloralkali salt. This process involves salt water brine filters and salt water purifiers for salt water filtration, salt water purification and salt water desalination.

Process characteristics:

HIGH-QUALITY PRIMARY BRINE
SS≤0.5ppm, [Ca2 +] + [Mg2 +] ≤0.5ppm
WITHOUT ANY FLOCCULANTS
Reduce costs and no additional ionic contamination;
SMALL FOOTPRINT
New projects can reduce more than 30% investment in primary brine;
WITHOUT ANY LIMITATION FOR RAW SALT
Suitable for raw salt with inverted calcium and magnesium ratio
Also applies to sea salt;
LONG SERVICE LIFE, HIGH STRENGTH, EASY TO CLEAN, EASY TO REGENERATE
Durable, easy to maintain
FILTRATION PORE SIZE: 50 NM
Lower pore size than the smallest filter paper(200 nm) in your analysis chamber

Process advantages :

SHORT PROCESS
Compared with the traditional process, CBS eliminates the need of clarifier, sand filter & pre-coated cellulose filter tube and cleaning & pre-coating workload and avoids the secondary pollution of silicon.

Compared with organic polymer membrane, CBS not only eliminates the need of process and equipment of pretreatment system, flotation with pressurized dissoluble gas and floated clarification but also eliminates the need of corrosive, harmful chemicals such as ferric chloride which reduces the corrosion damage of system equipment and piping, completely avoids the secondary pollution of primary brine.

LONG SERVICE LIFE
High-quality, high-strength inorganic ceramic membrane can work long-term under the pressure of 1MPa without affecting by acid, alkali, oxidants, etc.

Ceramic membrane surface does not have any possibility to occur the phenomena of tearing, corrosion, aperture stretch ,but organic polymer membrane surface does. The service life of ceramic membrane tube is up to 5years.

The filtration pore size is less than 50nm. The simple screening principle can make the SS of the filtered brine less than 0.5ppm, greatly reducing the load of the chelating resin tower and the pollution of the ion membrane.

ANTI-FOULING
CBS process adapts to high magnesium raw salt. Ceramic membrane has excellent anti-pollution ability, and works at a high concentration of contaminants (5 to 10%) with full use of "cross-flow" filtration, eliminates defects which filtered membrane is not tolerant to high magnesium and organics in a dead-end filtration mode and reduces the quality requirements of crude salt, broadens the scope of salt selection.

SMALL FOOTPRINT
Because of short process, less equipment, simple process control and simple operation, installation and construction area can be greatly reduced compared with other primary brine technologies. The technology is easy to combine with the traditional process, especially for the old device reconstruction project.
Nanofiltration Systems Sulfate Removal

Membrane filtration principle

Ceramic membrane filtration technology is based on a selective filtration through a pressure -driven membrane. The membrane has charged groups that selectively reject multivalent anions such as SO42-. The membrane does not separate monovalent ionic species such as Cl- or CLO3- from the feed solution.

To maximize the membrane area within a compact space, the membranes are packaged as cylindrical elements in a spiral wound configuration.

Feed brine floods the entire feed side of the membrane surface within the membrane element by flowing within a mesh spacer. Brine then permeates through the membrane, where the sulfate is rejected, and flows in a spiral pattern through the permeate carrier, towards the perforated permeate tube.

To achieve the required membrane area, several ceramic membrane elements are packed into several high-pressure housing. The high-pressure housings are arranged in series to provide the required number of stages to concentrate the sodium Sulphate solution.

The membrane filtration unit usually treats dechlorinated depleted brine from the chlor-alkali electrolyzer. It is at this location that the Na2SO4 concentration is at its highest and the NaCl concentration is at its lowest. Normally only a portion of the dechlorinated brine flow needs to be passed through the Sulphate removal system, the remainder bypasses the Sulphate remove system and is returned to the saturators.
Features:

1. Reduced purge of depleted brine
Substantial costs saving due to less NaCl loss
More Environmental friendly, less effluent

2. No secondary pollution
No need to use BaCl2 reagent which is toxic
No Barium treatment cost
No solid BaSO4 waste

3. No secondary pollution
Lower operating costs
Reduces effluent volume
Full recovery of sulfate and sodium chloride
Proven technology with many references

Organic Acid Fermentation Broth Clarification(2023年04月20日)

jiuwu — 2023-04-14T12:33:15+0900

https://www.jiuwumembrane.com/application/organic-acid-fermentation-broth-clarification.html

Although batch processes are currently used, a number of more advanced techniques have been investigated in order to improve the process efficiency of organic acid fermentation. Promising every result must have been achieved using the tangential flow filtration in the continuous fermentation systems.

One of the main advantages of tangential flow filtration is that the higher biomass concentrations are possible because cells are continuously recycled back to the fermentor. A dense population of cells not only accelerates production of lactic acid but also minimizes contamination by foreign microorganisms. Thus high cell density continuous systems could increase the efficiency of lactic acid production. It can also be applied to nictric acid production.

Lactic acid fermentation broth on the main performance of the membrane fouling is

A. Gel polarization fouling of, membrane surface. Lactic acid fermentation broth by centrifuge coarse filters, except for a small amount of mycelium and solids, but also contains a lot of protein, sugar and easily carbonized material. During the membrane filtration process of lactic acid purification, these substances are easily deposited on the membrane surface and formed gel polarization fouling.

B. Membrane pore adsorption, crystallization pollution. Adding an excess of calcium carbonate is to adjust the system pH, in this way, the excess calcium carbonate is easily occurred crystallization within the hole and in the membrane surface. In the actual operation, the pipeline can easily generate a short temperature difference due to the solubility of calcium lactate which is very sensitive to temperature, so the calcium lactate is also vulnerable to precipitation surface or deposition within the membrane hole and in the membrane surface.

In order to remove impurities, ceramic membrane contamination mechanism in the process of lactic acid fermentation comes down to mycelium, protein, sugar and gel polarization pollution caused by carbonized material in the membrane surface of the and crystallization pollution of calcium carbonate - calcium lactate within the hole and membrane surface. Reasonable cleaning membrane procedure is

Oily Wastewater(2023年04月19日)

jiuwu — 2023-04-14T12:32:45+0900

https://www.jiuwumembrane.com/application/oily-wastewater.html

Oily Water Treatment Process

In the production process of rolling, galvanizing, spraying, metal cutting, oil and alkali refining, a large amount of oily wastewater is produced. JIUWU company has been successfully applied to the treatment of oily wastewater with ceramic membrane technology, and there are many typical cases. JIUWU company can provide the overall process package of emulsified oily wastewater treatment, including the oily water filtration system.

The advantages of ceramic membrane process:

Acid/alkaline/oxidation chemicals resistance
Solvent stability
High thermal stability and steam disinfected
Wear ability and excellent strength
Stable over a wide pH range
Narrow pore size distribution
Easy to be cleaned and regenerated
No chemical agent, no new sludge

Cold rolling emulsion waste water
In order to eliminate the thermal deformation caused by cold rolling in the rolling steel production process, emulsion should be required for cooling and lubrication, thereby there are lots of cold-rolled emulsion wastewater. JIUWU company has adopted UF ceramic membrane + MBR integration technology to treat cold-rolled emulsion wastewater, which has achieved very good results.

Mechanical processing of industry oily water treatment system
The waste liquid and washing wastewater discharged from the metal products during the mechanical processing mainly contain impurities such as oil, grease and metal ions, and are highly polluting to the environment. The ceramic membrane integration technology developed by the company can be used for the oily water treatment and has good performance in handling this kind of wastewater.

Edible oil
For most of the countries, Edible oil processing units is one among the major economic zones.

For edible oil refinery industries, “water” is the main component for the process. The wastewater from oil processing industries contains both organic and inorganic content, which are produced after various processes like degumming, deacidification, deodorization and neutralization steps. The wastewater will be also highly acidic and oily with Sulphate and Phosphate content that cause serious threat to environment and mostly the aquatic life.

With the increasing demand on treating wastewater from edible oil processing units, membrane technology including ceramic membrane bioreactor and RO /NF combined process has been applied to treat edible oil processing wastewater.

Oil Field Injection Water(2023年04月18日)

jiuwu — 2023-04-14T12:32:16+0900

https://www.jiuwumembrane.com/application/oil-field-injection-water.html

1. Ultra-fine water treatment in oil and gas field

Qualified reinjection water can be obtained at one time using ceramic membrane integrated system to treat oily wastewater in oil and gas field (up to Grade A in SY / T5329-2012 standard).

With the continuous development of oil and gas fields, the water quality of the produced water is more and more complicated and the processing is more and more difficult. The traditional backwash filter is prone to cause filter material hardening, the filter media is not thoroughly cleaned, the water is not qualified and the life span is short, covers a large area and has other disadvantages, but ceramic membrane system using efficient "cross-flow" filtration, with high filtration accuracy, short process, small footprint, high integration, water stability and other characteristics. It has been proved by field test and engineering cases that it has good treatment effect on water flooding, polymer flooding and ASP flooding produced water.

Fields of application:
Oilfield water treatment
Fracturing return fluid
Drilling waste
Gas field produced water

2. Hi tech membrane treatment in oilfield conventional water flooding produced water

Conventional water-flooding technology is widely used in onshore oilfields and offshore oilfields in China. For low permeability and ultra-low permeability reservoirs, water injection quality directly affects the development effect of the oilfield. The ceramic membrane technology is used to finely treat the water flooding wastewater (patent number: 102225812A), and the water quality of the effluent reaches Grade A standard.

3. Membrane treatment in oilfield Polycondensation / ASP Flooding produced water

Due to the fact that the polycondensate sewage is very complex, with the characteristics of large viscosity, high degree of emulsification, complex composition, and difficult biodegradation, the traditional process cannot meet the demand of oilfield production. The oil and suspended particles of polycondensate sewage are removed to achieve the requirement of water injection in low permeability oilfield when using pretreatment integration ceramic membrane process (Patent No .104071919A).

Natural Rubber(2023年04月17日)

jiuwu — 2023-04-14T12:31:42+0900

https://www.jiuwumembrane.com/application/natural-rubber.html

Natural rubber, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water.

Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into rubber ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for marketing.

Natural rubber membrane is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and is extremely waterproof.

Centrifuged latex is processed into final articles by dipping, extruding, and coating. Different articles have different physical and chemical requirements, which means that the latex used in their manufacture must be modified by the addition of a great variety of substances that give each "formulation" its unique characteristics.

These characteristics are well-specified and must be carefully controlled.

Skim latex is generated during natural rubber processing centrifuged into fresh latex to become concentrated latex. Skim latex is a raw material for producing skim rubber block according to the low content of rubber particles in the range of 4-8% DRC.

Traditionally, skim latex is treated with sulphuric acid to produce cheap, low-quality rubber products of 5% skim rubber content. Not only does this method consume large quantities of the acid, which results in high production cost, more importantly, causing harmful pollutants to the environment.

JIUWU offers a safer, cheaper and greener option to produce skim rubber products of high quality. Through ceramic membrane filtration system, the rubber content in recovered skim latex can be concentrated to more than 15%, the same value in natural rubber without any form of chemical treatment. At the same time, permeate can be recycled.

https://www.jiuwumembrane.com/application/lithium-recovery-from-salt-lake-brines.html

The pretreatment workshop of lithium extraction from produced water process adopts the international leading gradient coupling membrane separation technology, and the potassium fluoride from salt pans is subjected to magnesium-lithium separation and lithium concentration process to obtain high-purity lithium-rich brine, and is sent to the lithium plant to produce battery-grade lithium carbonate. The operation of the membrane equipment is fully automatic, the lithium yield can reach 80%, and it is at the leading level in the lithium recovery from brines.

The process flow chart of the pretreatment workshop
The potassium fluoride from salt pans is thoroughly mixed with the fresh water sent from the boundary area to reduce the magnesium ion concentration in the brine and then sent to the pre-treatment unit. In the pretreatment unit, the brine is removed by sand filtration to remove large particles of impurities and then sent to an ultrafiltration filter to remove all solid suspended matter. The pretreated purified brine is mixed with the fresh water reused in the workshop to further reduce the ion concentration and sent to the magnesium-lithium separation unit. In the brine purification process, it is separated into magnesium in the brine by a nano-scale membrane separation process in a magnesium-lithium separation unit to reduce the ratio of magnesium to lithium produced by the brine, and the high-magnesium old halogen is converted into a pure lithium chloride solution, and then sent to a lithium chloride primary concentration unit. The primary concentration unit uses a reverse osmosis membrane to concentrate the lithium chloride solution to increase the concentration of lithium chloride, and at the same time, fresh water is recycled to the former unit for dilution of the brine to achieve an internal balance of production water. The concentrated lithium chloride solution concentrated by the reverse osmosis membrane enters the secondary concentration unit, and the unit is further concentrated by the electrodialysis membrane to concentrate the lithium chloride concentrated water, and finally, the lithium-rich brine is sent to the sinking lithium workshop to produce battery-grade lithium carbonate.

Technical advantage analysis
The high-precision anti-pollution ceramic ultrafiltration membrane is used to purify the brine water, which can remove all solid suspended matter in the brine. The water recovery rate is high, the regeneration is easy, the service life is long, and the long-term stable operation can be maintained under the complicated salt lake brine condition.

The imported magnesium-lithium separation special membrane has high separation efficiency, low magnesium content, unique lithium enrichment effect, low lithium content in the outer row, and low lithium loss.

The imported reverse osmosis concentrated membrane has high ion rejection rate, good lithium concentration effect, no phase change in the concentration process, no steam consumption, and low energy consumption.

Ceramic membranes (Porous Ceramic Membrane & tubular ceramic membrane) are available for microfiltration, ultrafiltration and nanofiltration as single-channel or multiple-channel elements with channel diameters between 2 and 16mm.

The principle of porous tubular ceramic membrane
The principle of the filtration is based on two opposing effects: on the one hand, the particles are transported by the filtration flux to the membrane where they cause an increase in concentration; on the other hand, concentration differences are again reduced by the turbulence of the cross-flow and by Brownian motion of the particles. Ceramic membrane separation has greatly improved work efficiency and quality.

During filtration by means of ceramic membranes made by JIUWU ceramic membrane manufacturer , the medium to be filtered flows through the channels of the membrane support. All particles whose size exceeds the pore radius of the membrane are retained. The particles /molecules build up in the concentrate. The filtrate permeates through the pores and depending on the procedure is subjected to subsequent process stages. This filtering method is also called "cross-flow filtration" or "dynamic filtration". Cross-flow management can achieve stable fluxes. Still, the cleaning of cross-flow installations needs to be applied from time to time. Cleaning is performed by means of backward flushing or chemical cleaning. There are various ceramic membranes for water treatment in the market, while JIUWU ceramic membranes for wastewater treatment perform very well.

WINE AND LESS
Membrane crossflow filtration is becoming the unique alternative to kieselguhr filters in wine industry with the developments in environmental and health regulations.

Crossflow filtration uses a selectively porous ceramic hi tech membrane that filters a liquid in order to purify or clarify it. The quality of the filtration is constant over time because the fouling is reduced because the filtering is made without any change of state of the filtered element, and never gets distorted. Membrane crossflow filtration is one of the environmentally-friendly wine filtration systems. During the filtration, no filter aid is used. In one step, crossflow filtration clarifies the wine, giving it a clear appearance and making the wine microbiologically stable. So it has very strong advantages in simplifying the steps before bottling and reducing or eliminating the need for some consumables.

A large amount of waste acid is produced in the production of titanium dioxide, a large amount of high-salt wastewater is generated in the post-treatment process, and some titanium dioxide is still lost after the CN filter. On the one hand, the titanium white industry suffers from increasingly strict Environmental constraints, on the other hand, waste acid, water, and titanium dioxide resources are huge. Therefore, titanium dioxide water treatment has received an increasing attention. Jiuwu hi tech has developed a series of membrane treatment technologies for waste acid treatment, titanium dioxide recovery, and water reuse.

Technical introduction

The membrane process is based on membrane separation technology. The salt and acid in the waste acid, the salt, and water in the waste brine are separated to achieve the acid and salt in the waste acid, and the salt and water in the brine can be reused. The removal rate of the metal salt in waste acid is over 98%, the recovery of titanium dioxide is 99.99%, and the water production index reaches the international first-class standard. The separation membrane is a cross-flow filtration method, which greatly reduces membrane fouling, delays the rate of membrane fouling, and improves ceramic membrane filtration efficiency.

Nanofiltration Systems Sulfate Removal

Membrane filtration principle

Ceramic membrane technology is based on a selective filtration through a pressure -driven membrane. The membrane has charged groups that selectively reject multivalent anions such as SO42-. The membrane does not separate monovalent ionic species such as Cl- or CLO3- from the feed solution.

To maximize the membrane area within a compact space, the membranes are packaged as cylindrical elements in a spiral wound configuration.

The china membrane filtration unit usually treats dechlorinated depleted brine from the chlor-alkali electrolyzer. It is at this location that the Na2SO4 concentration is at its highest and the NaCl concentration is at its lowest. Normally only a portion of the dechlorinated brine flow needs to be passed through the Sulphate removal system, the remainder bypasses the Sulphate remove system and is returned to the saturators.

Features:

1. Reduced purge of depleted brine
Substantial costs saving due to less NaCl loss
More Environmental friendly, less effluent

2. No secondary pollution
No need to use BaCl2 reagent which is toxic
No Barium treatment cost
No solid BaSO4 waste

3. No secondary pollution

Due to short process, less equipment, simple process control and operation, installation area and construction area can be greatly reduced compared with other technologies.
The newly built 1 million ton vacuum salt brine refining plant has a total of 2 floors with a size of 9m × 40m.

Technology introduction：
Brine from outside battery limit goes into reaction tank by brine pump after heated by steam mixer. Refining agent sodium hypochlorite,sodium carbonate and sodium hydroxide are added into the baffle tank where brine enters reaction tank.

After finishing dosing, crude brine is formed in the reaction tank. Sodium hypochlorite oxidizes and decomposes organic matters in the crude brine, and sodium carbonate reacts with calcium ions in the crude brine to form crystal precipitates of calcium carbonate, sodium hydroxide reacts with the magnesium ions in the crude brine to form a colloid precipitate of magnesium hydroxide. The crude brine completes the refining reaction and flows into the middle tank by gravity, and is sent to ceramic membrane filtration unit by feed pump after more than 1.0mm of mechanical impurities inside crude brine are removed by a coarse filter.

edible-liquid-salt-purification-technology-introduction

The inorganic membrane filtration unit adopts three-stage series "cross-flow filtration" mode. Crude brine pumped by feed pump is sent to the first stage filtering module through circulation pump and then concentrate coming from the first stage filtering module goes into the second filtering module, finally concentrate coming from the second stage filtering module goes into the third filtering module.

A small part of concentrated brine is discharged into salt sludge tank according to a certain proportion and concentration where flows out from the third filtering module outlet and the rest returns circulation pump inlet and mixes with crude brine send by a feed pump, which the ratio of solid-liquid of feed brine is got to adjust. The mixed brine flows into circulation pump inlet and starts a new cycle filtration through circulation pump which concentrates solid content is controlled and membrane velocity is also ensured.

Purified brine filtered by three-stage filtering modules is collected through permeate outlet of each filtering module and sent to make second brine purification by primary brine pump after mixing with sodium sulfite in the refining tank.

Degreasing process is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials.

Degreasing treatment is performed with aid of an aqueous solution containing detergents.

The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in degreasing baths until the need for renewal and/or replacement, to avoid loss of efficacy.

Using ceramic membrane technology, there has two fluids, one is permeated which is constituted by water and detergents present in the original bath, the other is concentrate which contains oils and suspended solids and that is back to oil removal tank. After ceramic membrane treatment, the concentration of oil in the degreasing tank can be maintained at a low and very stable concentration range, the quality of the cleaned steel plate is uniform. The emulsion oil in the waste liquid is subjected to demulsification to reduce the amount of surfactant used in the cleaning solution.

Separation principle
Selecting the appropriate ceramic membrane filtration precision, by utilizing the characteristics that oil molecules and water molecules differ by tens of times in size and hydrophilic membrane surface properties of ceramic membrane, oil molecules can be effectively rejected, and water, degreasing bath, and surfactant small molecules can be recycled through the membrane surface. The degreasing bath is concentrated by the ceramic membrane system, and the volume of the discharged waste liquid is greatly reduced.

Technical benefits
1. Oil is removed and decreasing baths can be recycled ;
2. Costs of adding chemicals are significantly reduced;
3. The usage of surfactant is greatly reduced because of SS removal ;
4. Regeneration period is prolonged to 6 months or more ;

CHEESE, MILK, WHEY AND FOOD PROTEIN
Concentrated milk proteins (MPCs) and isolated milk proteins (MPIs) are produced by ceramic membrane filtration of milk system and their dairy proteins are separated from fresh skim milk. They combine rich calcium with good thermal stability and refreshing mouthfeel. They are rich in casein and whey protein in the same proportions as skim milk.

Milk protein concentrates are widely used and are ideal for cheese products, artificial products, dairy drinks, infant nutrition, medical nutrition products (enteral foods), weight management products, powdered dietary supplements and sports nutrition products.

CHEESE,-MILK,-WHEY-AND-FOOD-PROTEIN

In general, milk protein concentrates provide a concentrated source of protein for sensory and functional properties in the final application process to meet nutritional value. Condensed milk protein serves as an alternative to whole milk powder (WMP), skim milk powder (SMP) and other milk powders, providing the same protein, or as a non-fat milk solid (MSNF). Compared with ordinary milk or skim milk powder, concentrated milk protein with high protein, low lactose characteristics.

The traditional ultra-high temperature sterilization process will destroy many of the active nutrients in milk but low-temperature ceramic membrane filtration technology completely subvert the traditional high-temperature sterilization of milk. The process of milk filtration and clarification is to make natural fresh milk fluid through dairy ceramic membrane technology and avoid heat denaturation of the protein, fully retain 99% of active immunoglobulin and 95% of lactoferrin and a variety of natural vitamins, milk calcium, minerals and trace elements and other nutrients in the state of low temperature and ensuring safety at the same time.

BACTERIAL REMOVAL FROM MILK

Like many foods, milk and its derivatives provide a suitable environment for spoilage microorganisms. Therefore, pretreatment and temperature, time parameters must be selected to control the growth of microorganisms. Heat treatment and centrifugal sterilization are the traditional methods of reducing total number of bacteria in milk and dairy products, but these methods have their own advantages and disadvantages. Traditional techniques to remove bacteria in milk have more steps and high cost, short life, environmental pollution, inconvenient cleaning. However, the ceramic membrane filtration of milk can well solve these problems.

Membrane technology in dairy industry is used to eliminate bacteria in milk, which is based on the fact that the membrane has different material retention rates in various components of milk, including bacteria and spores. Bacteria can make the rejection rate of more than 99%, while casein transmittance can reach about 99%.

Membrane separation technology has a good membrane flux and sterilization effect, can completely remove bacteria in liquid milk, at the same time the flavor of milk has also been improved.

Membrane separation technology for cold sterilization is the method of fresh milk is preheated to about 50 degrees and skim milk is got through milk cream separation machine. Then on the same day fresh skim milk makes dairy membrane filtration sterilization, combining with high-temperature instantaneous sterilization technology, to access to high quality dairy products. Such low-temperature sterilization retains a good flavor and nutrients, rich aroma.

Moreover, membrane cleaning is much easier to regenerate, so that membrane fouling can be controlled and a higher and more stable membrane flux can be maintained. The use of membrane separation technology for cold sterilization of milk, functional components can be retained during the re-separation activity, is an ideal method of sterilization of milk.

BACTERIAL REMOVAL FROM WHEY CASEIM

Casein is the basic component df ordinary cheese. In the cheese making process, casein is precipitated by the action of rennet enzymes,and a coagulum is formed consisting of casein,whey proteins,fat,lactose and the minerals of the milk.

Membrane separation technology is used to eliminate bacteria in milk, which is based on the fact that the membrane has different material retention rates in various components of milk, including bacteria and spores.Bacteria can make the rejection rate of more than 99%, while casein transmittance can reach about 99%.

Antibiotics Fermentation Broth Clarification(2022年08月20日)

jiuwu — 2022-08-19T17:30:56+0900

https://www.jiuwumembrane.com/application/antibiotics-fermentation-broth-clarification.html

Cephalosporin is the second class of β-Lactamase found in nature following by penicillin. Any of various broad-spectrum antibiotics, closely related to the penicillins, which were originally derived from the fungus Cephalosporium acremonium. It has many advantages of high efficiency, broad-spectrum, low toxicity and enzyme-resistance which has been developed four new products to its range. It belongs to superior antibiotics that its application is growing widely. Advanced production technique is very pressing to meet brisk demands of the market both domestically and internationally. Cephalosporin C, or simply as CPC, is the source of original nuclear（7-amino cephalosporanic acid）of various cephalosporium antibiotic.

During the production of CPC, frame filter press, rotate vacuum drum filter are still used as a means of separation to remove protein, mycelium, and solid particulates. The technical means available on site did not achieve satisfactory degrees of separation. Meanwhile, those methods are unable to separate the massive existences of soluble protein, macro-molecule organic matters from the broth. The filtered broth shows not high transmittance with residual insolubility and soluble impurities which would increase the difficulty in the downstream extraction process and have a bad effect on the quality and yield of final product. According to market adjusting, some companies are asked to improve separation performance by means of membrane technology and to reduce the product losses. With the wide applications of ceramic membranes, they will play a significant role in separation and purification of antibiotics.

Three steps are introduced in order to guarantee the yield of CPC in the process of filtration of fermentation broth for the production of CPC by ceramic membranes. Pre-concentration step is made to let feed volume Vo concentrate to Vd and permeates are obtained meanwhile; diafiltration step is to add cleaning agents in the wanted liquids while filtration and effective ingredients are got to reach a high yield ; post-concentration step is to concentrate wanted liquids to Ve aiming to treat residuals conveniently and improve yield further.

Ceramic membrane filtration system could intercept protein and solid particulates from the untreated antibiotic fermentation broth. The protein –removing the capability of this technology is 10 times as much as that of the original process, with filtration yield increasing by 6％. The attenuation range of membrane flow rate is narrow and thus a better product quality can be obtained.

The temperature of CPC fermentation broth from the fermented process drops to 10 below zero and it is acidified to pH2.5-3.0 by the use of hydrofluoric acid.

Then CPC clarity is got due to removing mycelium, suspended solids, and macromolecular protein through the filtration process. In the next refining process, macroporous resin adsorption and ion-exchange are applied, and then nanofiltration and reverse osmosis are also used to obtain concentrated CPC.
Spectinomycin
Spectinomycin is an older antibiotic from S. spectabilis whose structure contains an unusual tricyclic ring. Spectinomycin is sold under the tradename Trobicin among others, is an antibiotic useful for the treatment of gonorrhea infections. It is given by injection into a muscle.

In the process of spectinomycin bio-fermentation, there are many bacteria, protein, macromolecular pigment, insoluble starch and sub-micron particles in the fermentation broth. The presence of these impurities can cause blocking in the post-ion exchange adsorption or pollution in the post-extraction, affect the extraction and purification efficiency and lead to the decline of the quality of follow-up products, and even feed contamination, resulting in product scrap, so industrial production must be separated to remove such impurities.

Clarification fermentation broth is usually done by plate frame filtration, vacuum drum filtration, diatomaceous earth filtration, centrifugation, and other methods.

However, neither of these methods can completely and effectively separate the impurities in the fermentation broth, which can easily cause blockage and frequent replacement of the filter medium, thereby affecting work efficiency.

With many years of experience in filtration and hi tech membrane separation technology in the pharmaceutical industry, ceramic membrane filtration technology and organic membrane filtration technology are successfully applied to fermentation broth clarification process to solve the problem of clarification in the production of fermentation broth which achieves the goal of simplifying process, convenient operation, clean production requirements and development of advanced scientific and technological innovation.

spectinomycine
Erythromycin
Erythromycin is a macrolide antibiotic that has an antimicrobial spectrum similar to or slightly wider than that of penicillin and is often used for people who have an allergy to penicillins.

Erythromycin is mainly fermentation production. As the fermentation broth contains a large number of mycelium, protein and polysaccharide material, to the separation and extraction of erythromycin caused difficulties affecting their yield and quality. Therefore, before the separation and extraction of the fermentation broth need pretreatment. At present, a more commonly used method is flocculation and high-speed centrifuge. The former sterilization rates are relatively high, but the removal of proteins and polysaccharides less effective, resulting in a high solution viscosity, affecting the crystallization process of the follow-up; the latter large energy consumption, equipment is expensive, in the actual production is difficult to wider application.

During the production of erythromycin, frame filter press, rotate vacuum drum filter are still used as a means of separation to remove protein, mycelium, and solid particulates. The technical means available on site did not achieve satisfactory degrees of separation. Meanwhile, those methods are unable to separate the massive existences of soluble protein, macro-molecule organic matters from the broth. The filtered broth shows not high transmittance with residual insolubility and soluble impurities which would increase the difficulty in the downstream extraction process and have a bad effect on the quality and yield of final product. According to market adjusting, some companies are asked to improve separation performance by means of membrane technology and to reduce the product losses. With the wide applications of ceramic membrane filters, they will play a significant role in separation and purification of antibiotics.

Colistin sulphate is a mixture of the cyclic polypeptides colistin A and B and belongs to the class of polypeptide antibiotics known as polymyxins. Colistin sulphate is effective against most Gram-negative bacilli.

Colistin sulphate Separation and Purification technology is suitable for industrial production of modern antibiotics using microbial synthesis, which can replace traditional purification technologies such as adsorption, precipitation, solvent extraction and ion exchange.

colistin sulphate

Separation process provides optimum solutions with the unique characteristics without any chemical reaction, no phase change, does not destroy the biological activity, environment-friendly.

CLAVULANIC ACID
Clavulanic acid is a β-lactam drug that functions as a mechanism-based β-lactamase inhibitor.

In the process of clavulanic acid bio-fermentation, there are many bacteria, protein, macromolecular pigment, insoluble starch and sub-micron particles in the fermentation broth. The presence of these impurities can cause blocking in the post-ion exchange adsorption or pollution in the post-extraction, affect the extraction and purification efficiency and lead to the decline of the quality of follow-up products, and even feed contamination, resulting in product scrap, so industrial production must be separated to remove such impurities.

Clarification fermentation broth is usually done by plate frame filtration, vacuum drum filtration, diatomaceous earth filtration, centrifugation and other methods.

https://www.jiuwumembrane.com/application/amino-acid-fermentaion-broth-clarification.html

Amino acids are the basic unit of protein composition, most of the amino acid processes are through fermentation method. Fermentation broth is an extremely complex system and contains microbial cells, metabolites, unconsumed medium, etc.

The traditional method of amino acid production processes such as centrifuge and plate and frame pressure filtration, the filtrate quality is poor. Soluble protein, sugar, peptide, pigment and other impurities can not be effectively removed, increasing the processing load of the subsequent process, affecting overall yield of the extraction process, also affecting quality of final product.

Amino acids: lysine, glutamic acid, phenylalanine, threonine, tryptophan, glycine, arginine, glutamine, theanine, proline, valine, isoleucine

Ceramic membrane integrated organic membrane filtration process system has the unique advantages of high separation precision, maintaining high-throughput filtration and high product yield, less waste water, less cleaning frequency, without adding additives and achieved desalination and preconcentration of the target product which has been successfully applied to bio-fermentation enterprises such as glutamic acid production (sodium), lysine production, threonine production, tryptophan production, valine production and so on compared with traditional process.

Process features
Compared with traditional separation process, the quality of the filtrate is guaranteed due to high separation accuracy and uniform pore size distribution; high-throughput filtration can be maintained, and cleaning frequency is reduced because membranes have smooth surface to result in membrane flux slowly decay; Improve product yield, reduce the amount of wastewater, pore size diversification, suitable for different types of materials processing requirements;

Without adding additives, concentrated material (mycelium, protein, etc.) can be used as feed recovery;

95% of fermentation of bacterial cells integrity and activity can be guaranteed;

Organic membrane filtration is used to to remove small molecules protein or peptides, nucleic acids, dyes and other impurities from permeation generated by ceramic membrane and improve product purity and reduce sewage treatment load;

Achieve the desalination and preconcentration of the target product, and reduce the production load of subsequent processing technologies such as solvent extraction, ion exchange and evaporation concentration.

Xanthan Gum
Xanthan gum is a polysaccharide with a wide variety of uses, including as a common food additive. It is a powerful thickening agent, and also has uses as a stabilizer to prevent ingredients from separating.

Xanthan gum is known as "industrial MSG", is the largest and widely used microbial polysaccharide in the world at present.

Use of membrane filtration and separation operations allows concentration and purification of substances such as xanthan with recycling of permeate. It also provides an inexpensive and reliable way to remove water and low molecular weight impurities. Fractionation, concentration, and purification of gelatins via china membrane operations result in gentler processing to avoid denaturing the gelatine.

Vitamin
Vitamin C production has two fermentation processes: Reichstein method and two-step fermentation. Impurities in fermentation broth are removed by the use of heat precipitation method for the above two traditional vitamin C extraction process. After the fermentation broth was allowed to settle, it was separated by a cation exchange resin. However, the fermentation broth is passed directly through the ion exchange resin, which can cause serious contamination of the resin surface and reduce the exchange capacity.

Modern extraction process generally applies ultrafiltration membrane gulonic acid fermentation broth production, because the broth protein molecular weight range is generally 1-10kDa, so to choose a certain molecular weight cut-off can remove most of the protein and some macromolecular impurities in place of the traditional heating method to remove protein.

vitamins
Compared with the traditional process, Gulonic acid fermentation broth has obvious advantages: simple process, fully automatic operation and good stability; the yield is improved, generally reach more than 99% during membrane filtration for removing impurities. At present, integrated membrane technology including ceramic membrane, ultrafiltration nanofiltration membrane is applied to vitamin C production enterprises because membrane process has more important feature is the separation of relatively high accuracy, which can be verified from the fermentation broth protein removal rate.

Vitamins: Vitamin C, vitamin B2, vitamin B12 and so on.

What Is Enzyme Purification
FERMENTATION BROTH
Enzymes are biologically-catalyzed proteins produced by the metabolism of microorganisms and thus have poor heat sensitivity and are not resistant to high temperatures. However, the traditional process mainly concentrates the enzyme preparation by depressurization and concentration, which leads to the prominent problems of high energy consumption, high enzyme deactivation rate, high cost, low yield and multiple ash, which makes the product market less competitive.

Enzyme purification membrane separation equipment, the use of advanced membrane purification and membrane concentration process, can effectively purify and concentrate enzyme preparation. Because the enzyme membrane separation is a low-temperature process, so energy consumption is low, product activity is kept intact. In addition, membrane separation is the use of mechanical screening principle of the interception of the enzyme, so that small molecules of impurities and water passes through, so concentrated in the fermentation process can effectively prolapse of inorganic salts and small molecular impurities, the enzyme was purified, improve the enzyme quality .
