Dissolved Air Flotation Manufacturers in India
In today’s industrial and environmental landscape, wastewater treatment is not just a necessity—it’s a regulatory and ethical imperative. Among the various technologies used, Dissolved Air Flotation (DAF) systems stand out for their efficiency in removing suspended solids, oils, grease, and other contaminants from water. Whether in food processing, oil refineries, chemical plants, or municipal wastewater systems, DAF units offer a compact, energy-efficient, and reliable solution.
With increasing environmental awareness and strict CPCB (Central Pollution Control Board) norms in India, the demand for DAF systems has seen a sharp rise. Indian manufacturers are now producing highly advanced, automated, and efficient flotation units that meet international standards. One such trusted name in the industry is Kelvin Water Technologies Pvt. Ltd., a leading manufacturer of Dissolved Air Flotation systems in India.
What Is a Dissolved Air Flotation (DAF) System?
Dissolved Air Flotation (DAF) is a water treatment process that clarifies wastewater by removing suspended matter such as oil or solids. This is achieved by dissolving air in water under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny bubbles that adhere to suspended matter, causing it to float to the surface where it can be skimmed off.
Key components of a typical DAF system include:
- Saturation tank
- Pressure release valve
- Flotation tank
- Skimmer system
- Inlet and outlet piping
