Domestic sewage treatment Dissolved air flotation DAF plants with high SS purifying rate

Product Application

Pollutants in sewage can be divided into dissolved organic matter and insoluble matter (SS). Dissolved organic matter can be converted into insoluble matter. One of the methods of sewage treatment is to add coagulants and flocculants to transfer most of the dissolved organic matter to insoluble matter, and then clean up most of the insoluble matter. (SS) to achieve the purpose of purifying sewage, and the main method of cleaning SS is the use of air flotation.

After adding chemicals, the sewage enters the mixing zone of air flotation, and mixes with the released dissolved air water, so that the floc adheres to the fine bubbles, and then enters the air flotation zone. Flocculants float to the water surface under the action of air buoyancy to form scum. After the clear water from the lower layer flows to the clear water tank through the water collector, some part will reflux as the dissolved air water, and the remaining clean water flows out through the overflow outlet. When the scum accumulates on the surface of the air flotation tank, it will be scraped and discharged into the sludge tank.
