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.

Features

DAF system is widely used in industrial wastewater reuse, pretreatment system before membrane treatment, reclaimed water reuse, MBBR biological film process.

1. The bubble size is less than 10um, Dissolved gas efficiency is over 95%.

2. Land-occupying province,the solid suspended matter content in effluent can be less than 20 mg/L.

3. One-button boot, unattended, Cloud digital service can be realized.

4. Material of construction.
① Carbon Steel (Expoxy Painted).
② Carbon Steel (Expoxy Painted)+FRP Lining.
③ Stainless Steel 304/316L.
