Working Principle
Dissolved Air Flotation Process
The Dissolved Air Flotation (DAF) system is designed to effectively remove suspended solids (TSS), biochemical oxygen demand (BOD₅), and oils and greases (O&G) from wastewater. This process utilizes a dissolved aqueous solution of water, which is enriched with air injected into the recirculating stream of DAF effluent under pressure.
Once the recycle stream mixes with incoming wastewater in the internal contact chamber, air bubbles form. These bubbles lift contaminants to the surface, creating a floating layer that is skimmed off by a surface skimmer for further processing. This ensures high efficiency in wastewater treatment and sludge management.
