Abstract: A liquid-cleaning filtering system has at least one permanent filter assembly that is capable of being promptly backwashed thus minimizing the down time of machinery. Each filter assembly utilizes a wire mesh filter cartridge which is backwashed by a powered internal rotating sprayer nozzle assembly that is operable to deliver a plurality of high pressure streams of liquid to a surface of the wire mesh. Each filter assembly is capable of being repeatedly used and then backwashed in order to return it to a pristine state. The rotating spray nozzle assembly may be powered by hydraulics, pneumatics or an electric motor. A plurality of filter assemblies may be arranged together in a fluid processing center in order to process large volumes of industrial waste.

Abstract: A liquid-cleaning filter system with distillation capability has twin permanent filter assemblies, each utilizing a wire mesh filter cartridge which is backwashed using an internal sprayer nozzle assembly. During the normal operation of the filter cartridge, which is located in a pressurizable inverted bell housing, contaminates are filtered through a sheet of wire mesh arranged in a star configuration on a frame structure within the filter cartridge. The liquid filtering system is especially adapted for use in dry cleaning operations where a layer of diatomaceous earth and a layer of activated carbon deposited are on the wire mesh at the start of normal forward flow. Contaminates collect on this filter bed, thus cleaning the dry cleaning solvent.

Contaminates collect on this filter bed, thus cleaning the dry cleaning solvent. During the system's backwash cycle, filtered solvent previously collected in a steel reservoir is pressurized to provide a powerful head of pressure for backflushing each filter cartridge through its own sprayer nozzle assembly which reciprocates inside the cartridge. The high-pressure spray vigorously cleans the wire mesh of all suspended contaminants and filter bed particles.
