DAF dissolved air flotation filtration for Meat …

The multiphase pump dissolved air flotation system is a clarification process for the separation of solids, grease and oils. It works by using multiphase pump to mix water and air, then release it, producing a stream of micro-fine air bubbles that attach to solids and float them to the surface, where they can be removed by a surface scraping mechanism.

Dissolved Air Flotation for Membrane …

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. The air ...
