Introduction
DAF Wastewater Treatment, Coagulant and flocculant are added to the raw water, after the effective flocculation reaction time, the raw water enters the combined air flotation contact area. In the contact zone, the microbubbles in the dissolved gas water and the flocs in the raw water adhere to each other and enter the separation zone together. Under the buoyancy of the bubbles, the flocs and bubbles rise to the liquid level together to form scum. The scum is hung to the sludge area by the scraper. The clean water in the lower layer flows by itself to the clean pool through the water collection pipe. Part of the clean water is returned for use by the dissolved air system, and the other part is discharged.
