Dissolved air floatation machine for oil and water separator

Specifications

Dissolved air floatation machine

Application range:

Floating as sewage treatment a process, it is widely used in the sewage and water treatment, TDAF type air floated equipment is mainly used in the following aspects:
1. All kinds of heavy metal ions removal (electroplating mixed wastewater treatment)
2. Oil refining and all kinds of oily wastewater separation of oil and water
3. Tan wastewater treatment grease and remove chromaticity
4. Printing and dyeing wastewater treatment and impurity to color separation
5. After all kinds of biological wastewater treatment of membrane separation
6. Sludge concentration (processing power for equipment sewage treatment capacity of 20-30%)
7. In the water supply engineering to remove the algae
8. Casing processing wastewater treatment

Main features:

1. The structure is compact, easy to transport hoisting and convenient installation
2. Use the patent dissolved gas technology, dissolved gas system dissolved gas efficiency is more than 80%
3. The new release device, not easy jam, efficiency is as high as 99% above the release, the bubble diameter are both in the 50 um below
4. Equipment take control box, after testing can be up to the normal operation of fully automated

Working principle:
After the treatment of water (design index of 20-40%, usually by 30%) qi float circulation work pump, water soluble in air pressure and air blending, dissolved into the water, air, at this time of dissolved gas efficiency reached 80% or above; Dissolve the air in the air by level control instrument control air compressor, automatic added soluble in tank; Dissolve tank out of the water dissolved vapor, dissolve the pressure of the air at this time of 0.3 0.4 Mpa, after the release, dissolved vapor pressure water pressure release, dissolved vapor pressure to reduce water is zero or negative pressure, dissolved in water air released from the water, forming a particle size for 20 to 50 um's tiny bubbles, tiny bubbles in combination with sewage suspended, part directly grows in tiny bubbles in the suspended, the proportion of the suspended in the wastewater become smaller, floating on the surface of the water until; Form lots of scum, again by gas pool of chain scraping the float installation foaming machine, the scum cleared; Floating pool lower part of the water, the qing ShuiJi water pipe and into the floating QingShuiChi, except the part as a backflow dissolved vapor outside water, can be directly to the discharge or after entering primary treatment equipment.
