ABSTRACT:
An apparatus and process of filtering fluids, such as white water is provided for use in the place of an existing save-all device or downstream of an existing save-all device at a paper-making mill. The white water having contaminants in a suspended state is introduced into the filtration vessel and is withdrawn from the interior of the filter element positioned within the filtration vessel. To clean the filter element from the cake which has built up on the exterior surface of the filter element, a backflushing shock is applied to the interior of the filter element, forcing all cake settled on the exterior to be dislodged, thereby cleaning the filter element. The backflushing shock is delivered from a backflushing reservoir wherein the backflushing fluid is contained under pressure at a level at least slightly above the level of a pressure differential which has built up across the filter element. The shock is applied for a period of 1-2 seconds, during which time the backflush reservoir is emptied.
