dissolved air flotation system is an advanced wastewater treatment used mostly in the industrial sector in the country to treat wastewater algae, organics, oil and grease. it is very efficient for the reduction of chemical oxygen demand (cod) present in fat, grease, oil, biological sludge, coloured organic matter, and colloidal material.
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
from the time of the early 20th century, dissolved air flotation (daf) had been used in the separation process. in the daf system, air is dissolved in the wastewater under a pressure of several atmospheres, followed by release of the pressure to the atmospheric level.
pre-treatment of trade wastewater by a system based on the dissolved air flotation (daf) principle is a commonly used best practice option, where grease arrestors or other simple passive pre-treatment devices are inadequate. at its heart, micro fine bubbles of

dissolved air flotation (daf) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening. daf is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling.
