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. |
