Abstract: The present invention relates to a filter for liquids. More particularly it is concerned with providing a clog-resistant filter of the kind in which a filter element (usually of hollow cylindrical shape), having at least one open end and with walls of metal, plastic or other suitable material bearing numerous perforations, is placed within a housing in such a manner that the liquid entering the housing must flow from the inside of the filter element out through the perforations in the latter, before it can leave the housing, with the result that solid material strained from the liquid flowing through the filter is retained within the filter element.

Abstract: Rolling solutions used in cold rolling are pressurized and filtered at working temperature using a filter of the scanning flush type in which flushing nozzles exhausting to a low pressure zone are scanned over an upstream surface of the filtration medium during flushing cycles triggered by a pressure drop across the filter exceeding a predetermined level. Flushing retentate exhausted during the flushing cycles is treated in a secondary filter. Harmful particulates can be removed without retaining wanted components of the rolling solution.

Abstract: A disc filter including a stack of apertured filter discs arranged about an axis, the stack having an outer surface and an inner surface and being mounted such that during backflush, individual discs are rotatable relative to adjacent discs about the axis and a disc cleaning assembly operative to rotate at least some of the discs about the axis relative to others of the discs, the disc cleaning assembly including at least one first fluid conduit for producing at least one outer liquid jet directed generally tangentially into engagement with the outer surface of the stack for rotationally driving the at least some of the discs about the axis relative to others of the discs and at least one second fluid conduit for producing at least one inner backflushing liquid jet directed into engagement with the inner surface of the stack.
