We use grids to prevent duckweed and other contaminants of surface water.
With aid of the bar screen cleaner, we can clean these automatically. Hereby, the screenings will be placed on the duckweed bridge, or it can be drained with conveyor(s) or a flushing gutter. Both with new as with existing installations, the bar screen cleaner can be applied. So far, over two hundred copies have been in use.
