ABSTRACT:
A screen for a water intake has a movable filter element and a recuperation channel adjacent the filter element arranged below the lowest water level. The concavity of the recuperation channel faces the filter element. Suction is applied at the recuperation channel to cause an opposite circulation of water through the filter element at this point. The recuperation channel acts as a safeguarding device for living elements in the water and the opposite circulation of water at the channel detaches living elements from the filter element without traumatism and urges them into the channel. The channel is provided with a filter spaced from the filter element for preventing living elements being entrained by the filter element and carried to the air.
