Dissolved Air Flotation DAF Flocculant Machine For Oil Refining Wastewater Treatment




Dissolved Air Flotation machine is mainly for solid-liquid or liquid-liquid separation. After


flocculation, the sewage flows into the mixing zone and is mixed with dissolved air water. The


flocs are bonded to the small bubbles,floating up along with the small bubbles on the water


surface to form scum. The lower layer of clear water flows through the water container to the


clear water pool. Some of water returns as water steam. The remaining clean water flows out


through the outlet.The scums on the surface of the gas flotation pool are scraped by the


scraping board to the sludge pond.

(1) Long-term & stable performance, easy operation, easy maintenance, low noise;

(2) Micro bubbles and high adsorption of suspended particles to improve the SS removal


effect; Micro bubble size 10-30 microns

(3) Automatic control and easy maintenance


(4) Multiphase pump can replace the pump, air compressor, large tanks, jet, and the release


of the first class;

(5) Dissolved air water dissolving efficiency is 80-100%, three times higher efficiency than


traditional dissolved air flotation;

(6) dissolved air flotation machine to inhale, over the suction pump pressure within the mixing,


gas-liquid dissolving efficiency is high, the micro air bubble 20 microns or less;

(7) multilayer mud, ensure water effect;

(8) low voltage operation, the efficiency of dissolved air is as high as 99%, outgassing rate as


high as 99%.


(9) Overcome the touch device operation is not stable, large bubbles churning and release the


head congestion
