Abstract:
A closed-loop pressure washing system for pressure washing an object having a contaminant with a pressure washer device, and for recovering the contaminant, the apparatus comprising:a supporting mechanism arranged to support the object while a washing fluid is flowed over the object to remove the contaminant; a collection arrangement at least partially located below the supporting mechanism, and arranged to receive the raw run-off fluid from the supporting mechanism; and a flush assembly arranged to at least periodically spray rinsing fluid onto said supporting mechanism to hydro-dynamically entrain or sweep contaminants collecting on said support mechanism into said collection arrangement and, said support mechanism includes a pair of opposed sloped surface portions each extending from one end to an opposite and thereof, and each including and upper side portion and a lower side portion arranged to collectively form a V-shaped top support surface and, said collection arrangement having a collection trough positioned substantially adjacent to at least a portion of each said lower side portion of the respective sloped surface portion for gravity flow collection of the raw run-off fluid therein, and said flush assembly includes a pair of elongaged dispensing members each positioned substantially adjacent to at least a portion of a respective upper side portion of the sloped surface portion to provide a continuous spray of rinsing fluid therealong toward the lower side portion of the respective sloped surface portion.
