Abstract: A closed-loop wash system is provided for use with a washing assembly that includes a collection basin and a self-contained, bioremediation treatment apparatus. A housing assembly defines a plurality of chambers in series flow communication from an upstream collection chamber to a downstream clean wash fluid chamber. A central media chamber is included in upstream flow communication with the upstream collection chamber and in downstream flow communication with the downstream clean wash fluid chamber. An array of media housing microbes is disposed in the media chamber. The treatment apparatus includes a diffusion assembly configured to aerate the washing fluid contained in selected chambers. A first circulation system continuously circulates flow through the bioremediation system, while an independent second circulation system continuously circulates flow from the collection basin to the bioremediation treatment apparatus, and then back into the collection basin.

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.

Abstract: A closed-loop containment washer assembly for use with a pressure washer apparatus for washing an object containing a medium weight contaminant. The washer assembly includes a clean wash fluid basin, and a first collection basin configured and oriented to collect the run-off of a washing fluid after being flowed over the object to remove the medium weight contaminant. A first filter assembly is included having an inlet side in fluid communication with the contaminated washing fluid collected in the basin, and an outlet side for outlet flow of filtered washing fluid. A minority portion of the outlet flow is diverted into the clean wash fluid basin, and a majority portion of the outlet flow is diverted back into the first collection basin.

Abstract: A phosphatizing system for phosphatizing an object including a subfloor assembly for supporting an object, and adapted to direct excess run-off fluids which are flowed over the object and collected at a run-off discharge port thereof. A closed-loop phosphatizing assembly is configured to pass a phosphatizing reagent run-off fluid over the object during a phosphatizing procedure, and a having reagent fluid reservoir in fluid communication with the run-off discharge port for receipt of substantially all the reagent run-off fluids from said subfloor assembly. A rinse system is configured to pass a rinsing solution over the object to rinse the reagent run-off fluid therefrom during a finishing rinse procedure performed after the phosphatizing procedure, and having a rinse fluid reservoir in fluid communication with the run-off discharge port for receipt of substantially all the rinsing/reagent run-off fluids from said subfloor assembly.

Abstract: A closed-loop pressure washing system adapted for removal and recovery of high solids contaminants from an object. The washing system includes a support platform having a support surface that supports the object while a washing fluid is flowed over the object to remove the high solids contaminant. A collection device is provided in flow communication with the support surface, and is adapted to collect and channel the run-off washing fluid and run-off high solids contaminant from the support surface towards a collection basin. A high solids separation assembly is in flow communication with the collection basin, and is adapted to separate and displace the collected high solid contaminants from the collected run-off fluids in the collection basin to a discard region spaced-apart from the collection basin. This separation assembly, however, substantially maintains the run-off washing fluid in the collection basin.

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.

Abstract: A containment assembly for use with a pressure washing apparatus to contain and collect the relatively light weight contaminants from run-off of a washing fluid after being flowed over an object to be cleaned. The containment assembly includes a settling compartment for collection of the run-off washing fluid therein, and a containment compartment in gravity flow fluid communication with a surface of the collected washing fluid in the settling compartment. As the lightweight contaminants at the surface of the washing fluids gravity flow into the containment compartment, they are contained and collected therein. A fluid extraction assembly is in fluid communication with the contained washing fluid in the containment compartment through an opening therein vertically disposed below a predetermined operational fluid level of the contained washing fluid.

Abstract: A phosphatizing system for phosphatizing an object including a closed-loop phosphatizing assembly is provided configured to pass a phosphatizing reagent solution over an object during a phosphatizing procedure. The phosphatizing assembly includes a collection compartment in fluid communication with a run-off portion of a subfloor assembly supporting the object for receipt of substantially all the reagent run-off fluids from the subfloor assembly. A storage assembly is configured to pass a rinsing solution over the object to wash the reagent solution therefrom during a finishing rinse procedure performed after the phosphatizing procedure. This storage assembly includes a storage compartment in fluid communication with the run-off portion for receipt of substantially all the rinsing/reagent run-off fluids from the subfloor assembly.

Abstract: The present invention relates to methods and apparatus for removing a contaminant from an object. According to one aspect, an apparatus for washing an object which has contaminant is arranged to recover the contaminant. The apparatus includes a support floor that supports an object to be washed and a basin mounted below the support floor. The basin is divided into a plurality of chambers which include a clean water chamber, a secondary water chamber, an oil containment chamber, and a contaminated water receiving chamber which receives water which is contaminated after it is flowed over the object to remove the contaminant. The contaminated water received in the contaminated water receiving chamber must pass sequentially through the oil containment chamber and the secondary water chamber prior to entering the clean water chamber.

Abstract: A portable parts washer flows a washing agent over an object to remove any contaminants. The washing agent and contaminants flow into a basin mounted below the object. The washing agent is drawn from the basin and used to wash the object to provide a closed-loop system. A venturi-type injector mixes ozone from an ozone generator with the washing agent. A pump draws the washing agent from a first inlet to the basin, forces the washing agent through the injector, and returns the washing agent through a first outlet to the basin. Various splash protection mechanisms are used to protect an operator from any substances that may splash off of the object.
