Abstract:
A containment assembly for use with a pressure washing apparatus for washing an object having a contaminant comprising:a settling compartment adapted to collect the run-off of a washing fluid after being flowed over the object to remove the contaminant wherein the relatively lightweight contaminants in the collected washing fluid are caused to gravitate to the surface of the collected washing fluid therein;a containment compartment in gravity flow fluid communication with the surface of the collected washing fluid in the settling compartment such that the lightweight contaminants at the surface thereof flow into the containment compartment for containment of the lightweight contaminants and the washing fluid therein; anda fluid extraction assembly in fluid communication with the contained washing fluid in said containment compartment through an opening therein vertically disposed below a predetermined operational fluid level of the contained washing fluid, said extraction assembly being adapted to extract the contained washing fluid through the opening in a manner maintaining said gravity flow of the collected washing fluid into the containment compartment.
