ANALYSIS OF THE INTERVENTION:
The aeration basin has a diameter of 11,5 m and a liquid depth of approximately 5,20 m. The oxygen requirement is 21 kgO2/h in AOR conditions.
In order to aerate the activated sludge biological reactor, the choice of a pressurized aerator is preferred to diffusers or surface aerators for technical and economic reasons. The installed equipment is a pressurized radial aerator model SCLK 100-15 kW Double Winding. This unit is fed with a blower delivering 500 Nm3 / h pressurized air thru a flexible hose. The chosen aerator is provided with a double winding and can thus operate in agitation only mode.
Power consumption is measured less than 10 KW in aeration mode.
