H2Flow Dissolved Air Flotation System (DAF). A properly functioning DAF with a suitable chemical program can eliminate 95% or more of FOG, TSS and insoluble BOD. While a DAF system can prevent the pH and FOG violations, it may only reduce the BOD and TSS surcharges to an acceptable level, rather than eliminate them altogether.

Flotation. Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
