Electrocoagulation Wastewater Treatment Daf Dissolved Air Flotation

The dissolved air flotation (DAF) system is designed to remove solids (TSS), biochemical oxygen demand (BOD5), and oils and greases (O&G) from wastewater. Contaminants are removed by using a dissolved aqueous solution of water produced by injecting air into the recirculating stream of clear DAF effluent under pressure. The recycle stream is then mixed with the upcoming wastewater in the internal contact chamber.Air bubbles and contaminants rise to the surface and form a floating bed material that is removed by a surface skimmer into the internal hopper for further processing.

Air flotation separation technology refers to that the air and water under the certain pressure conditions makes the air dissolving to the water to the maximum, in saturated state, and then releases the formed pressured dissolved air water through decompression to produce lots of tiny bubbles and fully contacts with suspended solid ,then the suspended flocs adhere to the bubbles raising to the surface of the water companied with the bubbles, then scums are formed and scraped, to realize the purification of water.
The efficient shallow air flotation equipment developed by our company is an advanced high-speed air-floating system, based on the traditional theory of air flotation and the successful use of the "shallow theory" and "zero" principle.Through careful design, combines coagulation, flotation, skimming, precipitation and scraping mud functions in one is the efficient equipment for water purification.
