Water decanter Specifications
1.Treatment capacity:5-100t/h
2.decanter depth:500-4000mm
3.Material:carbon steel or ss

Unpowered float type water decanter process:
SBR and CASS fan pool water, gas, sludge precipitation, water decanter decantation water:
(1) equipment adopt the u-shaped rotational support, parts adopt stainless steel, with compact, smooth operation.
(2) the buoy floating design, can according to the pool water level changing and always decant water water depth is constant, to achieve the desired effect of the decantation water.
(3) equipment main body has no power to run, the overall equipment run time besides the eliminator equipped with electric valves, the remaining parts are not on any power.
(4) equipment runtime decantation water velocity uniformity, smooth surface no fluctuations, the main body power noise, decantation can finished water as the water level rising and buoyancy.
(5) the underwater rotating part adopts rotating machinery equipment, can guarantee the water decanter rotating part of the long-term operation without aging rupture.
(6) equipment body didn't use any rubber parts production, long service life.
(7) when the normal operation of equipment can pass to decant water electric valve range between 0 to decant largest water depth for adjusted freely.
(8) set water tank inlet is equipped with automatic fenders, aeration in the pool can effectively isolate the sludge.

As long as provide us the weir length, depth  , treated capacity , we can make different sytles and make competitive solution as per your different demand .
