By dosing suitable flocculant and coagulant into wastewater, grease removal rate can be more than 95%, suspended solids removal rate can be more than 90%, and around 60% COD and BOD can be removed at the same time.                       

CAF Cavitation Air Flotation Machine is greatly different from DAF Dissolved Air Flotation Machine in its air dissolving method: One or several sets of CAF aerator(micro bubble generator) is installed in the aeration chamber of CAF machine. With the high speed rotation of impeller of CAF aerator under water, a vacuum zone is formed there and absorb the air above water surface into water and generate millions of micro bubbles.

These bubbles attach to, and form with, the solids or chemical flocculants entering the vessel, causing them to float to water surface where they are retained and forms scum layer, which is then subsequently removed by CAF skimmer.

Cavitation Air Flotation Machine(CAF) is an advanced wastewater treatment equipment, mainly used to remove suspended solid, colloids and grease to achieve solid-liquid separation and liquid-liquid separation for industrial wastewater.
