induced air dissolved air flotation

Dissolved air flotation - Wikipedia

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 suspended matter to float to the surface of the water where it may then be removed by a skimming device. Dissolved

Induced Air Flotation - separates suspended solids, oil and grease

Dissolved Air Flotation. The WaterTectonics Dissolved Air Flotation DAF system separates suspended solids, oil and grease, and other insoluble impurities from water slurries. The process dissolves air into water under pressure. Upon release of the pressure, micro-bubbles form. These micro-bubbles interact with the particles to cause them to float to the surface of a vessel where they are skimmed and separated.

Abstract. Bench‐scale and pilot‐plant studies were used to investigate the effects of flocculation time and floe size on the performance of dissolved air flotation and to determine air requirements for three different types of water supplies. The results show that long flocculation periods are not needed and suggest that floe particles of 10–30 μm should be prepared for flotation.

Hydrocell TM Induced Gas Flotation Separators

What is dissolved Dissolved Air Flotation DAF

Dissolved air flotation. The air is dissolved in the water under pressure higher saturation concentration in a pressure vessel. By subsequently reducing the pressure again, relaxation, small gas bubbles are created in the order of magnitude of 20-60 µm. These micro air bubbles are introduced into a flotation unit to remove substances from the water by means of flotation.

Dissolved Air Flotation DAF for Oil/Solids Separation

In the case of induced air, known as IAF, recycled flow is pumped through an eductor and air is drawn into the flow, to be released as it enters the bottom of a separating vessel. Bubbles created in this way are rather larger than those created by the second option of dissolved air. IAF plants are generally used where low levels of contamination are present. In the dissolved air flotation method known as DAF ,
