Dissolved Air Flotation(DAF) System- For Water Clarification

Dissolved Air Flotation (DAF) is an efficient flotation method for water clarification.The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure.When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form.These bubbles attach to any particles in the water causing their density to become less than that of water. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

Applications

DAF is a proven, and effective physical-chemical technology commonly used for many industrial and municipal applications, including:

1. Product recovery and reuse.

2. Pretreatment to meet sewer discharge limits.

3. Pretreatment to reduce loading on downstream biological systems.

4. Polishing of biological treatment effluent.

5. Removing silt and grease from industrial water.

6. Overall specialized, compact structure, and high performance.

7. Huge markets, high maturity, stable performance and reliable operation.

8. Hydraulic load: 4~ 6 m³ / (m²h).

9. Maximum inlet SS concentration is 3000 mg/L.
