HYDRIG DRUM SERIES - DESCRIPTION ROTARY SCREENS

НYDRIG rotary screens of МF series are compact units of high capacity, designed for fine mechanical wastewater treatment. They are made of stainless steel AISI-304 and equipped with automatic washing system, providing continuous treatment.

Application:

  • filtration of biologically treated wastewater after secondary settling tank;
  • filtration of surface water for the pretreatment of drinking and process water;
  • water filtration for fisheries;
  • filtration of industrial water for re-use.

Treatment fineness is determined by the size of grid cell made of stainless steel wire or polymeric thread. The standard sizes of cells made of polymer threads are 23, 35, 43, 48, 55 micron.

Operation principle

Treated water is fed into rotating screen. Suspended solids are retained in the drum surface, gradually moving to the sludge collector, while treated water passes through grid cells and is removed for further use.

Part of the treated water is used to wash the drum. Water for cleaning is fed under pressure through a nozzle onto the outer surface of the grid. Built-in self-cleaning system starts to work as soon as the water level rises in the drum, which indicates the grid is clogged. The design feature of the HYDRIG filter of MF series is insertion of a thin-walled screw inside the drum. While washing, water knocks down slurry and the screw moves it out of the drum, which facilitates cleaning of the grid. The water used for washing seeps again through the mesh drum and the screw pushes the sludge into the sludge collector.

НYDRIG rotary screens of МF series are automatically-controlled, simple and reliable in operation and do not require high capital costs.
