Dissolved Air Flotation in Industrial Wastewater Treatment

Dissolved air flotation (DAF) is a process for removing suspended particles from liquid by bringing particles to the surface of the liquid. The influent feed liquid can be raw water, wastewater or liquid sludge. The flotation system consists of four major components: air supply, pressurizing pump, saturator (retention tank), and flotation chamber. According to Henry’s law, the
