Optigon, based on the Opti-Line

The process water exits from the dryer and enters the filter unit which is comprised of several screen elements. The water level in the filter unit is monitored. If the level rises, the filter unit is rotated by means of a gear motor so that clean screen elements are always in the filtering area. The dirty screens are cleaned by means of water jet cleaning nozzles. The contaminant is deposited into a filter cassette drawer which must be cleaned periodically. As an optional extra, a continuously operating belt filter is available in place of the filter cassette drawer.
