In Dissolved Air Flotation (DAF), water is pressurized and mixed with air to dissolve the gas into the liquid. Once the pressure is released, the dissolved air forms tiny microbubbles that attach to suspended particles in the water. These bubbles help lift the particles to the surface, where they form a layer of sludge.
The particles, now floating on the surface, are skimmed off by a surface scraper, while the clarified water is discharged from the bottom. This process efficiently separates solids, oils, and other contaminants from the water, making it cleaner.
DAF is commonly used in industries such as wastewater treatment, food processing, and oil refining, where it helps remove difficult-to-treat contaminants and reduces the overall pollutant load in the water. It is especially effective for water with low solid concentrations or oils.
