1. Laundry wash water recycle system, said system comprising:

  • a repressurization pump having a suction inlet side and a repressurization outlet side, said suction inlet side operatively coupled to an outlet channel of an inlet tank receiving and storing laundry wash water;

    a series device configuration comprising;

    a self-cleaning lint filter device having a lint filter inlet channel and a lint filter outlet channel, said lint filter inlet channel operatively coupled to said repressurization outlet side of said repressurization pump;

    at least one cyclone having an inlet port and an outlet port, said inlet port operatively coupled to said lint filter outlet channel of said self-cleaning lint filter device; and

    a multi-media filter having an inlet passage and an outlet passage, said inlet passage of said multi-media filter operatively coupled to said outlet port of said at least one cyclone wherein said repressurization pump provides pumping of the wastewater through said series configuration for delivering double filtered cyclonically processed water from said outlet passage of said multi-media filter;

    a clean water tank having an input channel and an output channel, said input channel of said clean water tank operatively coupled to the outlet passage of the multi-media filter for receiving said double filtered cyclonically processed water;

    an advanced oxidation means that combines ozone with hydrogen peroxide to produce a hydroxyl radical for treating said double filtered cyclonically processed water prior to entering said clean water tank for providing a double filtered cyclonically processed advanced oxidation treated water to said clean water tank;

    a clean water feedback line having a first end and a second end, said first end operatively coupled to the inlet tank;

    a clean water pump having an input operatively coupled to said output channel of said clean water tank and an output operatively coupled to said second end of said clean water feedback line and to the at least one washer machine for pumping said double filtered cyclonically processed advanced oxidation treated water from said clean water tank to the at least one washer machine upon demand while continually recirculating or feeding back a stream of said double filtered cyclonically processed advanced oxidation treated water through said clean water feedback line from said clean water tank to the inlet water tank for providing constant recirculation of said double filtered cyclonically processed advanced oxidation treated water through said system; and

    wherein said self-cleaning lint filter device comprises;

    a self-cleaning recirculation housing comprising a bottom having an outer circumscribing periphery transitioning into an upwardly extending circumscribing sidewall terminating to an upper circumscribing lip defining an upper opening of said self-cleaning recirculation housing;

    a lid mounted on said upper circumscribing lip of said self-cleaning recirculation housing forming a pressurized self-cleaning lint filter device;

    said upwardly extending circumscribing sidewall having an interior circumscribing surface defining a circumscribing main chamber that extends along and circumscribes a central longitudinal axis of said self-cleaning recirculation housing;

    a cylindrical screen filter disposed within said self-cleaning recirculation housing, said cylindrical screen filter having a diameter less than an interior diameter of said self-cleaning recirculation housing;

    said cylindrical screen filter having an inferior end abutting an interior surface of said bottom of said self-cleaning recirculation housing and a superior circumscribing collar radially extending away from a superior end of said cylindrical body of said cylindrical screen filter and circumferentially spacing said cylindrical body of said cylindrical screen filter away from said interior circumscribing surface of said self-cleaning recirculation housing for forming a hollow cylindrically shaped envelope between an exterior of said cylindrical body of said cylindrical screen filter and said interior circumscribing surface of said self-cleaning recirculation housing; and

    wherein said hollow cylindrically shaped envelope is bounded by said superior circumscribing collar of said cylindrical screen filter, said bottom of said self-cleaning recirculation housing, said interior circumscribing surface of said self-cleaning recirculation housing, and said exterior surface of said cylindrical screen filter.
