With the discharge of industrial wastewater, domestic sewage and agricultural water, the problems of eutrophication of water bodies are becoming more and more serious. Some rivers and lakes even have the situation that the water quality turns black and smelly, and a large number of aquatic organisms die. There are many river management equipment, and micro-bubble generator is a very important one. How does a micro-bubble generator work compared to a normal aerator? What are the characteristics? Today, I will introduce it to you!

There are many tiny air bubbles in the water body, which can provide oxygen for the water body and purify the water body. The so-called micro-bubble generator refers to bubbles with a diameter of 100 nm or less. The bubble generator uses this principle to purify the water.
Features of the micro-bubble generator:
1. Relative increase in surface area
Under the condition of the same volume of air, the number of micro-bubble generators is much larger, the surface area of ​​bubbles also increases accordingly, the total area of ​​contact between bubbles and water also increases, and various biochemical reactions also increase exponentially. The water purification effect is also more obvious.
2. The bubbles rise more slowly
The volume of the bubbles is small, the rising speed is slow, and the bubbles stay in the water for a long time. Considering the increase in the specific surface area, the dissolving capacity of the microbubbles is 200,000 times higher than that of ordinary air.
3. The bubbles can be automatically pressurized and dissolved
The dissolution of the micro-bubble generator in water is a process of gradually shrinking the bubbles. The increase in pressure will increase the dissolution rate of the gas. With the increase in the surface area, the shrinking speed of the bubbles will become faster and faster, and finally dissolve into the water. Theoretically, the pressure when the bubble is about to disappear is infinite. The bubbles have the characteristics of slow rising speed and self-pressurized dissolution, which can greatly improve the solubility of gases (air, oxygen, ozone, carbon dioxide, etc.) in water.
4. The surface of the bubble is charged
The gas-liquid interface formed by the micro-bubble generator in water is more attractive to anions than cations, so the surface of the bubbles is often negatively charged, so that the bubbles can adsorb organic matter in the water, and can also have antibacterial effects.
