"Micro nano bubbles" are micro and nano scale water bubbles, which are generated when bubbles occur in water by using physical principles. They can also be called micro and nano bubbles, micro bubbles or nano bubbles according to their diameter range. The diameter of ordinary water molecular group is 200-400 μm, and the diameter of microbubbles is less than 50 μm, which is 2.5% - 10% of the size of ordinary water molecular group. When the micro bubble contracts to less than 10 μ m in water, it will burst under pressure, and a large number of negative oxygen ions which are beneficial to human body can be produced when high temperature and pressure are generated instantaneously.

The number of bubbles in water is large when doing the microbubbles cleaning, which greatly increases the gas-liquid contact area and improve the dissolution efficiency.

When the bubble diameter is reduced to 1/a, the bubble area will increase a times, and the number of bubbles will increase to a³;

Single volume reduces to one tenth of the original, and its surface area increases to 10 times. That is to say, the surface area of bubble contacting with water increases 10 times (that is, the gas dissolution efficiency increases 10 times).

The bubble size is 1mm, and the particle size is becoming 1/100 (the diameter is reduced to 10 μm), and the theoretical dissolution efficiency is increased by 100 times.

The time of microbubbles cleaning is long and the buoyancy is large, and it will rise to the water surface quickly and vertically to break away from the water surface. Because of its micron size, the micro nano bubble has a small buoyancy (3mm / min), and its rising speed is slow, and it moves horizontally, upward or downward. Under pressure, the fracture energy of the bubble will be released, and the active oxygen molecules will be dissolved in the water, and the micro nano bubble will continue to exist in the water.

When the microbubbles cleaning and burst happens, it will produce high temperature and pressure and ultrasonic wave, which will decompose the oxygen in the water into highly active negative ions, making the microbubble with weak negative charge. The concentration of negative oxygen ion in micro nano bubble water is 100 times of that in forest. So it can play a role of cleaning.

How Air Bubble Generator Works(2020年09月23日)

https://www.edonpump.com/

Usually we call the existence of gas in liquid bubbles. The formation of bubbles can be encountered in many processes in the nature. When the gas is affected by the shear force in the liquid, bubbles of different sizes and shapes will be formed.

At present, the classification and definition of bubbles are not very strict. According to the order from large to small, they can be divided into centimeter bubble (CMB), millimeter bubble (MMB), micron bubble (MB), micro nano bubble (MNB) and nano bubble (NB). The so-called micro nano bubble refers to the bubble with a diameter of about 10 microns to hundreds of nanometers when the bubble occurs. This kind of bubble is between the micro bubble and the nano bubble, which has the physical and chemical characteristics that the conventional bubble does not have.

The air bubble generator is to inject nano bubbles into the dirty water, but it is not these bubbles that really purify the water quality, but the original microorganisms in the water. They are in the nano level, and will not diffuse and disappear after being injected into water, but will gather and integrate into a bubble layer and suspend in water. The microorganisms in water supply create a high oxygen environment suitable for their growth. In the process of growth and reproduction, microorganisms will eat the pollutants in the water as food, so as to purify the water.

The working principle of air bubble generator:

It uses the high-speed rotation of the impeller to form a vacuum area in the water. The air on the liquid surface enters the water through the gas transmission pipe to fill and cut, then the microbubbles are generated, and rise to the water surface spirally, and the oxygen in the air also enters the water. The sewage is fully mixed with the microbubbles produced by the impeller in the process of rising. Due to the imbalance between the gas water mixture and the liquid, a vertical upward buoyancy is generated, bringing the solid suspension to the water surface.

The air bubble generator can make the gas in the sewage dissolve in large quantity and effectively, improve the dissolved oxygen rate, and greatly improve the treatment efficiency and treatment effect. Through its own micro vibration reaction, the ultra-fine nano bubble generator stays in the sewage for a long time, which has the effect of sealing the gas.

Fabrication Method of Micro Bubble Generator(2020年09月23日)

The micro bubble generator is to dissolve air, oxygen, nitrogen, hydrogen or other gases in the water in the form of extremely fine bubbles. According to the actual needs, different gases can be dissolved in the water to achieve the desired effect. Generally, the smaller the particle size of nano bubbles, the higher the bubble concentration, the larger the effective contact area with the water body, and the more conducive to the absorption of other substances or organisms in the water body. This will make a great breakthrough in aquaculture, plant root growth, cleaning function, wastewater treatment and beauty bathing.

Especially in the treatment of black and smelly river, only the natural dissolved oxygen in the water body can not achieve the removal of black and smelly, so it is necessary to take the measures of increasing oxygen to ensure the deodorization. Aeration is usually achieved by mechanical means to ensure that the appropriate dissolved oxygen can be achieved in the case of anoxia or uneven distribution of dissolved oxygen in the pond. At present, all kinds of aerators are based on the diffusion principle, and the diffusion rate depends on the degree of hypoxia, the surface area of water and air contact, the degree of water agitation and other factors. Oxygen can promote the up and down exchange of water, increase the dissolved oxygen in the air, and play the role of water dialysis and removal of black odor.

Decontamination mechanism of micro bubble generator: at the moment of bubble rupture, due to the drastic change of gas-liquid interface disappearance, the concentrated high concentration ions on the interface will release the accumulated chemical energy at once. At this time, a large number of hydroxyl free radicals (·OH) can be excited and produced, which has ultra-high oxidation-reduction potential. The super oxidation produced by it can degrade the water pollutants that are difficult to be oxidized and decomposed under normal conditions in the water, thus realizing purification of water quality.

In the current market, the main method of making micro bubble generator is to mix the gas and liquid by pump, and then produce bubbles after mixing, cutting and destroying the water molecules.

According to the different generation mechanism, microbubble generation technology can be divided into five categories: dispersed gas, induced gas manufacturing, micro pourous media, shear contact and electrosis.

The first two types are widely used in industrial practice, and the typical application examples are dissolved air flotation and induced air flotation. The bubble of dissolved gas is to dissolve the gas into the water under a certain pressure, then depressurize the dissolved gas water, and the dissolved gas will be released from the water in the form of microbubbles; the bubble of induced gas is to inhale the gas through the negative pressure effect produced by the venturi jet or the rotary cutting of the impeller, and further break it into microbubbles. Objectively speaking, it has the following shortcomes, for example, the system composition of conventional dissolved gas bubbles is relatively complex (compressor, packing dissolved gas tank, dissolved gas releaser, etc.), and the operation and maintenance cost is relatively high. Although the equipment for producing bubbles is relatively simple, the bubble size obtained is large and the uniformity is not high, which affects its wide application. Although the microbubble generation technology based on the gas-liquid mixing pump involves the mechanism of dissolved gas separation and shear contact foaming due to the different structure, it will make the shear emulsification more serious for the oily wastewater treatment and other occasions, but it is not conducive to the subsequent separation process. Moreover, the design and manufacturing technology of high-performance gas-liquid mixing pump has not been independently mastered in China.

With the continuous progress of material forming and manufacturing technology, microporous media materials with sufficient porosity, strength, stiffness, corrosion resistance and wear resistance are emerging. Microporous media foaming technology is increasingly concerned because of the advantages of simple system composition.

The working principle of this technology is that when the high pressure gas passes through the microporous medium layer, it is cut into a fine air flow by the microporous on it, and then the microbubbles are formed under the action of flow shear or scouring of the liquid. According to the materials of microporous media layer, corundum, rubber, high-density PE, metal powder sintering, ceramics, etc. are commonly used as materials of metallurgical powder, ceramics or plastics, and then mixed with appropriate adhesives such as phenolic resin, which are sintered at high temperature; from the shape of microporous media layer, there are round tube, flat plate, cover plate, bell cover, round arch, ball head, etc. For example, corundum microporous aerator, HDPE covered microporous aerator and rubber membrane microporous aerator used in aerobic biochemical treatment of sewage are typical microporous medium foaming technology products.

The technical principle of microbubble generator is that the surface of microbubble is negatively charged, and the negative charge of microbubble generator is higher than that of ordinary microbubbles. Generally, the surface load of microbubbles below 30um is about - 40mv, which is one of the reasons why microbubbles can gather together for a long time without breaking. Using the electronegativity of micro bubble, it can adsorb the positively charged substances in water, which has a good effect on the adsorption and separation of suspended solids or pollutants in water.

The technical principle of microbubble generator is that the self pressurization of microbubbles is related to the internal pressure and surface tension of dissolved bubbles. The smaller the diameter of bubbles, the greater the internal pressure. Due to its small diameter and large specific surface area, the internal pressure of microbubbles is much higher than that of the external liquid, while due to the advantages of internal pressurization and large specific surface area of microbubbles, the gas solubility of microbubbles is hundreds of times of that of millimeter bubbles. Because the solubility is closely related to the pressure, the interface will reach the supersaturated state when the internal pressure of the micro bubble increases to a certain threshold. When more gas in the bubble is dissolved into the water, it will gradually dissolve and disappear.

The technical principle of microbubble generator is that the shrinkage of microbubbles will shrink or expand continuously after they are produced in water because of self pressurization, and the diameter of microbubbles will change all the time. According to the latest research, 20um ~ 40um bubbles will search to 8um at the speed of 1.3um/s, and then the shrinkage rate will increase dramatically, and then it may further split into nano bubbles or completely dissolve in water. The surface of the bubble with high interfacial electromotive force will absorb charged ions such as OH -, and around the OH - ion layer, there will be counter charged ions such as H +, so that the surface of the bubble will form a double electric layer. The potential of the double electric layer interface is also called the interfacial electromotive force. The level of the interfacial electromotive force largely determines the adsorption performance of the bubble interface.

Because of the shrinkage of micro bubbles, charge ions gather at the interface of bubbles in a period of time. Until the bubbles are completely broken and dissolved, the dynamic potential of the interface will increase all the time, showing the better adsorption performance of charged particles in water.

Micro bubble generator is a new generation of high-efficiency, energy saving and environmental protection technology. It has a wide range of distribution, and has great potential for development. With the characteristics of micro nano foam (foam with negative ions has slow moving speed, the equivalent of ozone bubble detonation can play a bactericidal effect, air bubbles will gradually become smaller and so on) it is familiar to people.With the continuous maturity and development of micro bubble generator manufacturers technology, its utilization scope will continue to expand, and the market will grow accordingly.

Micro and nano bubbles are different from ordinary foam plastics. Generally, because of the quick effect of air bubbles, the general foam plastics will merge and split up, and the diffusivity in water will be poor. When the solution is implemented, it is only limited to some natural environment of water quality, while micro and nano bubbles have very high bubble relative density and transverse diffusivity. In real life practice, if we fuse large bubbles and explode gas, we can make stronger effect. Because the large bubble explosion can aggravate the thermal convection of water quality, greatly accelerate the external diffusion rate of micro and nano bubbles, it has a very good positive significance to resist the thermal damage and material circulation of temperature stratification. The harmful substances such as ammonia in the low layer water can also be cleaned by the promotion of thermal convection. The excellent diffusivity of micro and nano bubbles can reduce the bubble generation point, maintain environmental protection and energy saving solutions, and integrate solar power generation to maintain large water quality drift solutions in large sea areas.
