Dissolved Air Flotation (DAF) is a widely used wastewater treatment process that separates solids, oils, and greases from wastewater, thereby improving its overall quality. This process is particularly effective in treating industrial wastewater, where it plays a crucial role in preventing harmful substances from entering the environment.
The Flotation Tank is the main vessel where the actual separation process occurs. The pressurized white water is released into the flotation tank. The sudden reduction in pressure releases the dissolved air in the form of tiny bubbles which motivate particles in the wastewater will ascend to the surface.
