thickening belt sludge flotation cell

There are several different processes used to achievesludge thickening, such as gravitythickeners, gravitybelt thickeners(GBTs), rotary drumthickeners(RDTs), centrifugalthickening, and dissolvedair flotation(DAF)thickening. Process configuration, energy consumption, chemical and labor requirements, and the extent ofthickeningachievable vary among differentthickeningmethods.
