Dissolved Air Flotation PPT

Dissolved Air Flotation (DAF) is a water & wastewater treatment system that uses air pressure for removes contaminants like oil and suspended solids. In the DAF system wastewater is treated by dissolving air in wastewater under pressure and then released at atmospheric pressure in a flotation tank basin.

  1. An Introduction to Dissolved Air Flotation (DAF). Brought to you by Kelvin Water Technologies Pvt. Ltd Environmental Consultant

  2. What is Dissolved Air Flotation? Dissolved Air Flotation is a water or wastewater treatment system which uses air for water treatment. In this air under pressure is dissolved in the wastewater which when released at atmospheric pressure in flotation tank basin removes the oil and solid wastes from the water.

  3. How does it works? DAF is particularly suited to water supplies with characteristics such as those containing low-density particles and those yielding low-density particles following chemical coagulation. Feedwater is added to the DAF float tank which transforms the small particles into big particles by coagulating the smaller particles to form a cluster. This coagulation is done by adding coagulants like ferric chloride and aluminum sulfate. Then the effluent water is pumped to the small vessel in which with the help of an air compressor, air pressure is maintained which helps unsaturation of pressurized water with air. Wastewater is recycled through recycling pumps passing through air compressor to air drum & then into float tank again leaving the waste on the surface.

  5. Advantages of DAF 01 The DAF method has a Low-head round tank. 02 It can produce higher water quality. 03 It has greater dependable effluent quality. 04 It works effortless without the use of a plate pack. 05 Flotation technique has numerous system benefits over sedimentation 06 It is operating at high floor loadings, ensuing in tremendously small and shallow plants.
