Abstract
A closed-loop pressure washing system including a pressure washer device for pressure washing an object having a contaminant, and for recovering the contaminant. The pressure washing system includes a supporting mechanism arranged to support the object while a washing fluid is flowed over the object to remove the contaminant. A collection arrangement is included at least partially located below the supporting mechanism. The collection arrangement is further arranged to receive raw run-off fluid from the support mechanism. A flush assembly is arranged to at least periodically impinge rinsing fluid onto the supporting mechanism to hydro-dynamically sweep contaminants collecting on the support mechanism into the collection arrangement.

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 raw run-off fluid from the support 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.
A separation assembly for use with a closed-loop pressure washing system to separate contaminants from raw run-off fluid, said pressure washing system having a pressure washing device to deliver pressurized rinsing fluid and a collection arrangement to collect raw run-off fluid therein, said separation assembly comprising:
- a separation tank defining a storage cavity for storing reusable rinsing fluid therein,
- a delivery device having a delivery port oriented to eject the raw run-off fluid into said storage cavity in a manner causing said reusable rinsing fluid therein to impart a rotational flow sufficient to enable centrifugal forces to assist in the separation of the heavier contaminants out of said raw run-off fluid.
