How Dissolved Air flotation Systems for Water Treatment

13/02/2018· Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter The DAF process dissolves air in the water under pressure – then releases it at atmospheric pressure The dissolved air flotation process

SERIES: PRIMARY TREATMENTS wateractionplan
