Clarifying Treatment Dissolved Air Flotation Provides

The air bubbles are generated in a pumped recycle stream by an air compressor and are dissolved in water through a packedtowertype of saturator. The floated sludge is removed periodically to a desludging trough, and the clarified water flows to the bottom of the clarifying chamber and then to an effluent control weir for collection.

Installation, Operation amp; Maintenance Manual

A DAF (Dissolved Air Flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. Once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. The treated wastewater then exits from near the bottom of the DAF.

Dissolved air flotation

Dissolved air flotation is a water treatment process that clarifies wastewaters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the

The amount of air that can be dissolved in DAF systems is limited by the laws of physics and is usually less than 2 4% air by volume. The recirculated whitewater is drawn and created from underflow of flotation units, requiring high horsepower compressors and pumps that often require frequent maintenance and operator attention.
