The DCV-R cable-rake screen is a fixed-width bar screen installed in a flow channel. A header with the cleaning rake, drive motor, drive cables and position sensors sits above the operating floor.
Large debris is collected on the front of the bar screen in the flow stream. As dictated by water level (or manually), the open rake is lowered by the cable down the screen frame to the bar screen. The rake closes when it reaches the bottom of the bar screen, trapping collected debris between the rake and the screen. The rake then retracts and carries the screenings up the screen frame to the header box where an ejector blade discharges the screenings from the rake into surface-level skip bin.
