Dissolved Air Flotation - an overview ScienceDirect

Some DAF systems do not have a pressurized recycle system, but, rather, the entire forward flow on its way to the flotation tank is pressurized. This type of DAF is referred to as “direct pressurization” and is not widely used for treatment of industrial wastewaters because of undesirable shearing of chemical flocs by the pump and valve.
