    NON-METAL SLUDGE SCRAPER

    DWA designs, manufactures and supplies non-metallic sludge collectors for primary & secondary rectangular sludge settling tanks in sewer and wastewater treatment plants on international market. Non-metal sludge collector is characterized in its anti-corrosiveness and easy installation by the lightweight of materials applied, and most of plants on the world tend to install non-metallic sludge collectors on their sewer, wastewater, and desalination plants. Primary sludge settling tanks collect settled sludge by flights to sludge hopper in the end of settling tanks and remove floated scums by the run of flights on the top of system to scum skimmers. Surplus sludge will be removed in secondary sludge settling tanks

    ROTARY AUTOMATIC SCREEN

    Automatic rotary bar screens are Installed on inlet side of river water intake and pumping station to lift-up trashes and screenings automatically in raw water. The opening of bar is 50mm mostly. Wet parts contacting water are made of stainless steel. Double chains are also made of stainless steel. Rotary operated chains are installed both end sides of equipment and lift trashes and screenings by 4 rakes automatically. Different reduction ratio of geared drive system (CYCLOID) is applied. Lifting weight is 350kg/cycle. Inclination of screen is 75 degree. Pitch of screen, number of rakes, space of bars, rotation speed, and others, are adjustable at the design stage of equipment, according to customer`s requests.
