Principle diagram for nanobubble water dialysis
The working principles of the nanobubble water dialysis technology
1, Increasing the dissolved oxygen concentration and aerobic biological activity in a fast and persistent manner in order to improve activity of aerobic organism;
2, Producing large amount of negative oxygen ion, killing anaerobic bacteria and algae in water;
3, Nanobubble with negative charge will make solid solubility and chemical substances flocculate and go up;
4, Anion may degrade sediment in water body and cut off the black smelly water source;
5,Forming eco-system and complete self-repairing of water body
The surface of nanobubble has strong tension which may constantly shrink in the water to a certain degree and then disappear in the water body which is the reason of its strong oxygen dissolving ability. The bubble becomes smaller during shrinking process and the air pressure inside the bubble increases quickly in inverse proportion which make the gas inside the bubble under super-high pressure. This super high pressure together with super high temperature effect is the main reason for nanobubble to produce ultrasonic wave. Therefore long-time and effective oxidation reaction and bacteria killing is available.
Negative charge exits on nanbubble surface, so it's difficult for two bubbles becoming one. Thick and fine bubbles will form in water which will not become one and break as normal bubbles. Instead, these thick and fine bubbles may absorb substances with positive charge in the water. By this absorption ability of surface charge on fine particles in water, the organic suspended substances in the water body will be fixed and separated which result in flocculation effect which is the key property for its super separation function in water treatment.
