Dissloved Air Flotation

Product Description

The dissolved air flotation(DAF) system is designed to remove suspended 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 wasterwater 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.
