Wastewater treatment is a critical process for protecting the environment and ensuring public health. An important aspect of wastewater treatment is dissolved air flotation (DAF). DAF is a process that uses air bubbles to remove suspended solids, fats, oils and grease from wastewater. The air bubbles attach to the pollutants and float them to the surface of the water so that they can be easily removed.

Working Principle

DAF works by dissolving air in water and then forming tiny bubbles after the pressure is released. These tiny bubbles, after mixing with the wastewater, absorb the suspended matter and form scum, which causes the solid particles in the wastewater to float. The scum can be separated from the water by a scraper system or other methods, thus achieving the purification of the wastewater.

Product Composition

DAF systems usually include components such as gas generators, dissolved air devices, wastewater feed ports, scum collectors and clear water discharge ports. These components work together to ensure efficient removal of solid particles and organic matter from wastewater. The DAF system can be adjusted according to the type of wastewater treated and the water quality requirements to achieve the best treatment effect.

Advantages

1. It can handle high concentrations of suspended matter, so it is suitable for treating wastewater containing a large amount of solid particles.
2. The DAF system has a small space requirement and can be deployed in a limited site.
3. DAF can also effectively remove suspended matter and grease, so that the wastewater meets environmental protection standards.
