Dissolved Air/Gas Flotation (DAF/DGF) is a liquid/solid separation process that clarifies wastewaters by the removal of suspended matter such as oil and/or solids. The removal of oil and or solids is achieved by dissolving gas in the water or wastewater under pressure and then releasing the gas at atmospheric pressure in a flotation tank. DAFTECH Floatcells are circular in shape, ranging in diameter from 1.2 to 16.8 meters and a liquid depth of only 0.65 meter. The complete set up consists of a flotation tank, feed pump, pressure pump, compressor, air mixing tube, chemical feed system and a spiral scoop for collection and removal of floated sludge.

COCO DAFF (counter-current dissolved air flotation filtration) is an innovative combined flotationfiltration design in which air and water flow counter-current as against co-current in the conventional dissolved air flotation process (Fig. 7.6 and Plate 12(b)). Air is introduced with recycle water across the total tank sectional area below the flotation zone and therefore only the filter surface loading rate should include the recycle flow. Dissolved Air Flotation Theory of Operation. If you are unfamiliar with basic DAF separator design principles, a review of the Dissolved Air Flotation Theory of Operation might prove helpful.This basic document covers Stokes law and other basic separation concepts.

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. The subsequent analysis compares the energy consumption of the thickening and digestion process with and without the addition of dissolved air flotation thickening.

Feb 13, 2018 Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water then releases it at atmospheric pressure. Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including Product recovery and reuse
