Design and operating principle

Has a form of a rotating mesh drum with a check valve block. The whole structure is mounted on three sealed metal pontoons. The rotation of the drum is carried out due to the energy of the water supplied through a rubber hose from the pump station to the hydraulic turbine wheel nozzle that rotates the drum through a gearbox and a pair of gears. Self-cleaning of the drum is carried out by jets of water from flushing nozzles, to which water is supplied from the pump station with a pressure of at least 3 bar. The design provides for the adjustment of the deepening of the drum depending on the depth of the reservoir.
