About Dissolved Air Flotation - DAF Corp

Note the shallow tank and all wetted parts are stainless steel construction. The top bridge rotates around the tank rim once every three minutes or less. Normal tank water depth is 18". Normal rise rate of suspended solids is 10" to 12" per minute. Dissolved air flotation clarifiers operate effectively over a wide range of hydraulic and solids ...

Dissolved air flotation - Wikipedia

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) 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 suspended matter to float to the surface of the water where it may then be removed by a skimming device.

Dissolved Air Flotation - an overview ScienceDirect Topics

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.

Ovivo® DAF Dissolved Air Flotation

Dissolved air flotation is best applied to remove materials that normally settle slowly, persist by remaining in suspension, or have a tendency to float. Benefits of flotation are rapid process results – flotation happens immediately while sedimentation takes time, higher loading rates than gravity thickening, and fresher sludge / solids.

Dissolved Air Flotation

Air to solid ratio is the principal desing paramter for a dissolved air flotation system. It is a theoretical measure of the quantity of air available per quantity of solid to be removed. Typical values range between 0.005 –0.06 ml/mg. For the air dissolving saturator vessel, the relation between A/S ratio, solubility of air, operating pressure,

Dissolved Air Flotation (DAF) – Ideal DAF™ - Technologies ...

Dissolved Air Flotation (DAF) systems remove suspended solids, fats, oils, greases and non-soluble organics by a process of dissolving air into water under pressure. The process begins with the water to be treated entering the DAF through an influent header box that reduces velocity and distributes the water across the length of the vessel.
