Surface Wash
Solutions

Surface wash systems are buried in the top of the filter media or are suspended above the filter media surface. Rotating arms use jets of water to break up the clogged filter surface and to rotate a movable arm through the filter material. A surface wash step in a backwash cycle usually takes place at the beginning of the filter bed cleaning process
