Closed-loop containment assembly and method for a pressure washing apparatus with a non-recirculating fluid heating compartment
First Claim
1. A closed-loop containment assembly for use with a pressure washing apparatus for washing an object having a contaminant comprising:
- a fluid collection basin adapted to collect the run-off of a washing fluid after being flowed over the object to remove the contaminant;
a filter assembly having an inlet side and an outlet side, said inlet side in fluid communication with the contaminated washing fluid collected in said basin;
a clarifying tank having an upper positioned inlet in flow communication with the outlet side of the filter assembly, and including a baffle assembly defining an under weir at a bottom portion of the clarifying tank and a downstream over weir at an upper portion of the clarifying tank such that a relatively vertically deep flow path down under the under weir and up over the over weir is defined;
a relatively vertically deep clean fluid reservoir in fluid communication with said over weir of the clarifying tank, said clean fluid reservoir being free of any outlets configured to enable recirculation of clean washing fluid therein directly back into at least one of said filter assembly and said clarifying tank; and
a heating device configured to heat the clean washing fluid contained in said clean fluid reservoir to heat.

Abstract
A closed-loop containment assembly for use with a pressure washing apparatus for washing an object having a contaminant. The containment assembly includes a collection basin adapted to collect the run-off of a washing fluid after being flowed over the object to remove the contaminant. A filter assembly includes an inlet side and an outlet side, wherein the inlet side is in fluid communication with the contaminated washing fluid collected in the basin. A vertically upstanding clarifying tank provides a relatively vertically deep flow path defined by a first baffle wall and a second baffle wall. The first baffle wall downwardly distends from a top portion of the clarifying tank to form an under weir with a bottom portion of the clarifying tank, while the second baffle wall upwardly distends from the bottom portion to form an over weir with the top portion thereof. The clarifying tank includes an inlet fluidly coupled to the outlet side of the filter assembly, and is positioned proximate the top portion and upstream from the under weir. The containment assembly further includes a relatively vertically deep clean fluid reservoir in fluid communication with the over weir of the clarifying tank. The clean fluid reservoir is free of any outlets configured to enable recirculation of clean washing fluid therein directly back into at least one of the filter assembly and the clarifying tank. A heating element is positioned in the clean fluid reservoir to heat the clean washing fluid contained therein.
