Abstract:
1. A recycling apparatus for recycling wash solution from a power washer: a first holding tank constructed and arranged for holding a first filtered wash solution and having a first outlet through which the first filtered wash solution can flow; a first filter assembly in gravity feed relation with the first holding tank and being constructed and arranged such that during operation the wash solution filters through the first filter assembly to form the first filtered wash solution and drops into the first holding tank a first distance of from about 1 to about 30 inches before contacting the first filtered wash solution contained therein, the first distance being sufficient to aerate the first filtered wash solution contained in the first holding tank during operation; a recycled wash solution tank constructed and arranged for holding recycled wash solution; a second filter assembly comprising a filter having a size of about 10 microns or less in gravity feed relation with the recycled wash solution tank and being constructed and arranged such that during operation the first filtered wash solution flows out of the first outlet and enters and flows through the second filter assembly to form the recycled wash solution and drops into the recycled wash solution tank a second distance of from about 1 to about 30 inches before contacting a surface of the recycled wash solution being contained therein, the second distance being sufficient to aerate the recycled wash solution contained in the recycled wash solution tank during operation; a power washer in communication with the recycled wash solution in the recycled wash solution tank; and screen structure constructed and arranged for collecting wash solution sprayed from the power washer during operation and transferring the wash solution to the first filter assembly.
