Dissolved Air Flotation Systems (DAF) Remove TSS, BOD ...

Dissolved Air Flotation is based on a physical / chemical process, where the injection of air into the water stream with chemical assistance causes the particles/flocks to float to the surface. This floating sludge layer is then automatically and continuously removed by a scraper mechanism. The DAF system will produce a treated effluent virtually free of TSS, FOG and remove a large portion of the BOD.
