Description
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. 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
Dissolved air flotation Features :
1）Material of Mild steel , SUS304, SUS316L for optional . Can be used in wide range of water and industry wastewater treatment .
2）Adopt with sludge hopper .Better performance on sludge sedimention and collection .
3) Dissolved air content as much as 10%. Diameter of the tiny bubbles 5 to 10 microns in the dissolved air
4. )Surface hydraulic load: 10 ~ 15m³ / (㎡.h), 3 times higher than the ordinary DAF System ;
5) Outlet SS can be less than 5mg / l
6) Dissolved air system adopt high-efficiency jet atomization of dissolved air, efficiency up to 99%. Jet nozzle flow rate up to 15m / s, nozzle minimum diameter of 15 mm or more, no clogging, maintenance-free;
7) Releaser  device is made of plastic material, suitable for different sewage, corrosion resistance;
8) Releaser with efficient decompression,come into 5 to 10 microns of small bubbles group,no blocking, easy maintenance;
9) Excellent performance, fully automatic control, realize unattended operation.
