DAF is an alternative clarification process that uses micro air bubbles to attach and float flocculated particles and suspended solids to the water surface for removal
Before the flocculated water enters the clarification chamber, millions of tiny air bubbles are released from the diffuser nozzles into the incoming influent stream, which attach to and float the flocculated particles to the water surface. These micro air bubbles are generated in a pumped recycle stream of clarified water (from the DAF), into which compressed air is also introduced, and are then dissolved in water through a tower-type pressurised saturator. The air saturator is used to dissolve air in the water and then generate bubbles to float the floc particles.
