Working principle:

Air-floating separation technology means that air and water are dissolved in water under a certain working pressure, and the air is dissolved in a state of saturation. Then, the formed pressure-dissolved water is released by decompression, and a large amount of fine bubbles are generated. It is in full contact with the suspended flocs in the water, so that the suspended flocs in the water adhere to the micro-bubbles, and float to the surface with the bubbles, forming into scum and then scraping it off, thereby purifying the water.

Air floatation mainly acts as a solid-liquid separation (while reducing COD, BOD, chromaticity, etc.). The flocculant PAC or PAM is added to the raw water, and after the effective flocculation reaction (the time, the amount of the flocculant and the flocculation effect must be determined by the experiment), the raw water enters the combined air-floating contact zone. In this zone, the micro-bubbles in the dissolved air and the flocs in the raw water adhere to each other and enter the separation zone together. Under the action of the buoyancy of the bubbles, the flocs rise together with the bubbles to the liquid surface to form into scum. The scum is scraped by the scraper to the sludge zone. The lower layer of clean water flows through the collecting pipe to the clear water pool. Some of the water is re-circulated for use in the dissolved air system and the other part is discharged.
