Description
Dissolved Air Floatation is mainly for solid-liquid or liquid-liquid separation.
Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or
liquid particles with same density as waste water to make the whole float to the surface thus
achieve the aim of solid-liquid or liquid-liquid separation.

Advantage
(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
