Abstract: A method and apparatus for cleaning a filter apparatus in which liquid influent is passed through web filter material on a rotatable filter frame into a filter effluent compartment and wherein the filter material is intermittently backwashed during a filter time by a suction device at an outer side of the filter material which draws filtered liquid from filtered effluent compartment in a backwash direction through the filter material, and wherein the filter material on the filter frame is subjected to a wash operation during a wash time by directing a high pressure liquid spray at one side of the filter material. The pressure in the suction device during backwashing is monitored, and the wash operation is initiated after the pressure in the suction device reaches a preselected sub-atmospheric pressure.
