Dissolved Air Flotation for Membrane Pretreatment

In the dissolved air flotation process, raw water particles are flocculated and separated out of the water by floating them to the surface rather than settling them to the bottom of a basin. The process introduces micron-sized air bubbles through diffusers that span the width of the tank at the bottom of the contactor where they mix with the coagulated solids and float the floc.
