Operating theory and function
The theory of the equipment is to inject high pressuried air into the dissolved tank, in order that the pressuried return flow contains saturated air, and then the pressure releases in the inlet tube,at the moment the saturated air discharges tiny bubbles due to depressure, and the bubbles adhere to the surface of the floc and lift the floc to water surface, by this way it reaches solid-liquid separation results. Besides, due to the floc keeps floating, it causes floc squeezes; the process is like concentration effects, therefore the concentration of the scratched floc can reach 10000-20000ppm. So only sludge deposit tank is needed to install, no need for sludge concentration tank.
Cost and construction
the treatment efficiency of the equipment is extreamely high (6m3/m2/hr), therefore the initial cost of the equipment is lower than the other solid-liquid separation equipment with same water volume. And the equipment is a package equipment manufactured in our factory, so it takes only 3-5 days for installation in the field.

Operation and maintenance
After setting gas-liquid ratio in the test-run, the equipment can operate stably. Check the operation pressure of dissolved tank, the flow volume of air and return flow volume daily.
Since the liquid connection part of the equipment is sus304, there is no problem of corrosion protection of the barrel groove. It's only needed to change grease on the rotation wheels regularly. The water in tank can be drained out in a short time during annual manentance, so it economizes manpower, unlike general solid-liquid separation equipment which possibly spends many days to pump out hundreds m3 of water, sludge and refill water.
