OPERATION
The central part of the supracell consists of two circular sections. The inner section contains the sludge well and is fixed while the outer section rotates along with the spiral scoop at a speed synchronized with the flow. The inlet, outlet and sludge removal mechanisms are all located in the central rotating section.
The variable speed gear motor drives the rotating elements and the scoop, for which electrical current is fed from a rotary contact mounted on the central shaft.Unclarified water is released through a rotary joint in the centre of the tank, it then passes into the distribution duct that moves backward with the same velocity as the incoming water, thus creating ZERO VELOCITY.. The settling and the floatation processes take place in this quiescent state.
