Automatic rotary bar screens are Installed on front of river water pumping stations to lift-up trashes and foreign materials automatically in river water incoming. Automatic rotary trash bar screen plants are consisted of numbers of rotary screens, horizontal belt conveyor, inclined belt conveyor, and hopper. Running of automatic rotary bar screens, belt conveyors, and hopper is automatic interactively. Rotary bar screens are mostly made of mild & carbon steel tar epoxy coated, and stainless steel 304, and 316. The opening of bar space is 50 to 60mm. Double chain system at both side are applied and the chain is made stainless steel. 4 to 5 rakes are applied typically and the speed of rake rotation is 5.0 m/min. Lifting weight for each rake is 300 to 500kg/cycle. Installation degree of rotary bar screen is 75°. Drive system is variable such as motor, hydraulic coupling, and gear box, or motor with Cycloid reducer to control smooth and long duration of run of equipment. DWA has so many references for Automatic Rotary Trash Bar Screens in South East Asian countries such as Malaysia, Thailand, Vietnam, since 2014 and has contributed to successful run of river water pumping stations for the proper water supply and flood prevention in the territory.
