How It Works

The RakeMax CF consists of a U-shaped stationary bar rack installed between the two screen frames, which sit parallel to the flow direction of the wastewater. As the wastewater flows into the open front side of the screen and out through both the left and right frames, solids are retained on the inner surface of the U-shaped bar rack. The solids retained on the bars lead to gradual blinding of the surface, creating a water level difference in the channel. When a defined water level is reached upstream of the screen, the screen bar cleaning begins. The RakeMax CF cleaning elements are attached to a chain system. The number of screening elements attached to the chain system is variable and adjusted to individual requirements. At the end of the bar rack cleaning cycle the rake itself cleaned by a pivoted comb that reliably discharges the removed screenings into a downstream transport or disposal unit. In the event the screening operation is blocked, an electric control reliably protects the screen against damage caused by overload. This easily accessed drive unit sits above the channel.
