Dissolved air flotation

Dissolved Air Flotation (DAF) has been known and applied widly as one of the most effective and economic ways to remove suspended solids?(SS),fats, oils and grease?(FOG), phosphorus?(P)?from industrial wastewaters by the generation of micro bubbles.

Jorsun DAF is an innovation combined with traditional dissolved air flotation design theory and modern technology after years of research and application.DAF is based on a?physical / chemical process.Wastewater is dosed with treatment chemicals upstream of the DAF inlet to form flocs.

When those flocs enter to the DAF chamber,massive of?microbubbles?attach to the flocs, and bring them floating to the top.The floating solids are harvested by DAF’s top skimmer. After the separation process, clean effluent will be collected and discharged.

The generation of micro bubbles is through the?air saturation vessel?and?air diffuser plates.A portion of the DAF effluent is recycled to the air saturation vessel to mix with air by?venturi jet?under high pressure,and form?air dissovled water(white water) .When the air dissoveld water flow to the air diffuser plates, the sharp reduction of pressure will make the microbubbles release from the air dissolved water,and form massive microbbubles.
