The Folded Flow® dissolved air flotation (DAF) separator is a significant innovation in water and wastewater flotation technology. Simple in concept, it "folds" the flow by removing effluent from the same end of the tank as the influent is introduced. This results in a higher hydraulic loading rate. The Folded Flow® hydraulic design takes ...

Under pressure, the dissolved air flotation system releases and dissolves air in the waste water. In the rise-up period, bubbles adhere to suspended matters and floats to the water surface where it is then removed a skimming device. As for matters that are denser than water, they descend to the bottom and may then be released to the sludge tank.
