What Is Dissolved Air Flotation?

Utilizing the characteristics of different solubility of water under different pressures, micro-bubbles are generated in the water under the condition of pressurized or negative pressure, instead of the traditional air-entraining equipment to bleed air into the water.

Dissolved air flotation is mainly used in sewage treatment systems and has a wonderful effect on algae removal. It is a new breakthrough in sewage treatment systems.

The working principle of dissolved air flotation is that the air sent from the air compressor to the air tank is taken into the dissolved air tank through the jet device, and is forced to dissolve in water at a pressure of 0.35Mpa to form dissolved water and sent to the air flotation tank. in. In the case of sudden release, the air dissolved in the water precipitates to form a large number of micro-bubble groups, which are in full contact with the suspended matter in the sewage that is pumped and flocculated after dosing, and adsorbed in the slowly rising process The agglomerated suspension will reduce its density and float to the water surface to achieve the purpose of removing SS and CODcr.
