Dissolved Air Flotation DAF Flocculant Machine For Oil Refining
Wastewater Treatment
Description
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.

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
