Abstract
Apparatus for the release and recovery of living organisms collected or trapped on the rotary filters of water pumping stations. The apparatus comprises: PA0 on the inside of the filters, a system of two rows of multiple washing jets using water under low pressure, whose nozzles are directed towards the filter panels, so that the jets of the two rows meet one another and cooperate to form a single liquid stream; PA0 deflectors arranged at radial intervals on the outer face of the filter panels; PA0 on the outside of the filters, a channel shaped like a trough for receiving the washing water and recovering the living organisms, whose opening is oriented towards the said rows of washing jets, the edge of the opening being rounded or rotary in its lower part.
