How it works: After dosing the reaction effluent into the mixing zone after flotation, dissolved air mixed in contact with water after the release, so that floc adheres to the fine bubbles, and then into the flotation zone. Air buoyancy effect floc formation of dross in the fall to the water, the lower water flow through the sump to clean water tank, the part of the dissolved gas reflux for use, the remaining water flows out through the overflow opening. DAF water surface scum buildup to a certain thickness after the scraping foam machine after scraping into flotation machine sludge tank discharge. Effective dissolved air flotation system flotation system combines water, flocculation, separation, water harvesting, water in one, similar to traditional flotation device, has a steady flow chamber, dissolved air release chamber, the processing performance is more stable, the effect superior, is particularly suitable for the transformation of the traditional equipment. Stability chamber: by flaps reaction raw water flow rate is high, if direct contact with the dissolved gas and water, tiny bubbles will dissipate impact bubble buildup floc effect, thus reducing the efficiency of the flotation process, if the increase in the steady flow chamber to raw water turbulence kinetic energy, uniform water containing dissolved gas is released into the chamber, which will effectively ensure the removal. Release of dissolved air chamber: release of dissolved air chamber and the separation chamber in a tank. Intermediate separated, dissolved air water and raw water flocculation is completed in this adhesion, slowly rising into the flotation separation chamber, to ensure that the contact space flocs and fine bubbles with time, so that the release of dissolved gas and water rate 80-100 %
