Product Description

Shallow DAF Dissolved Air Flotation is a water treatment process that purifies wastewater (or other water) by removing suspended matter such as oil or solids.

Working principle

Shallow DAF Dissolved Air Flotation works by dissolving air in water or wastewater under pressure and then releasing atmospheric pressure of air in the flotation cell basin. The released air forms tiny bubbles that attach to the suspended matter, causing it to float to the surface, where it can then be removed by a skimming device. Wastewater from the balance tank enters RT1 (coagulation reaction tank) and RT2 (flocculation reaction tank) through the lift pump, coagulates with PAC, and forms flocs with (PAM) respectively. Then the waste water and dissolved water enter the reaction zone of the DAF tank, and the microbubbles and flocs in the dissolved water are mixed and adhered to form solid particles with a density lower than that of water, which float to the surface of the DAF tank. Under the action of buoyancy, the scum is scraped to the slag pool. The clean water is collected downward to the water collecting tank through the water collecting pipe, most of the external water is discharged (or enters the next process), and a small part of the water is recycled to form dissolved water.
