Abstract: An improved hot water pressure washer utilizes a combination of technologies to achieve lower emission levels and increased operational efficiency. A forced air natural gas or forced air oil burner utilizes a flue gas and recirculation line to lower carbon monoxide and NOx emissions from a burner. A flue gas heat exchanger is utilized to lower the temperature of the exhaust gas. The lower exhaust gas temperatures allow for lower cost materials to be utilized. The efficiency levels of a hot water pressure washer are increased over known devices.

Abstract: A system for pressurizing and dispensing one or more fluids is provided. A chemical or cleaning agent is connected to a high pressure pump to entrain a first volume or flow of fluid with a cleaning agent. The cleaning agent or chemical is applied to the system and flow path of the system at various different locations. Spray guns and washing wands for use with various systems are also provided.

Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.

Abstract: A system and process for continuously and immediately removing contaminants from wastewater and treating wastewater, where the wastewater is treated to supply fluid that can be reused in the cleaning system or discharged safely into the environment is disclosed. The system and method comprises one or more pumping means for circulating and recirculating fluids captured or collected by the system to one or more of the processes in the system, such as wash water applications or further treatment cycles. According to one embodiment, the wastewater is transported through purification sections of the device. Depending on the system used, these sections could include several of the following: pretreatment to remove debris and certain heavy solids; treatment by methods such as a conductivity solution injection system and/or electrolytic coagulation system, a polymer injection system, and a inline mixer for mixing the polymer in the wastewater stream; and an ozone treatment system.

Abstract: A system and process for removing contaminants from wastewater where the wastewater is treated into a cleaned water that can be reused or discharged into the environment. The wastewater is transported through purification sections, depending on the system including several of the following: pre-treatment via screening and weirs to remove debris and certain heavy solids; a second pretreatment via a sump; strainer; conductivity solution injection system and electrolytic coagulation system; polymer injection system; inline mixers for mixing the polymer in the wastewater stream; retention tubes for providing residence time for the polymer to react in the wastewater stream; a multi-stage separation system comprised of a plurality of water separation compartments for consecutively separating contaminants from the wastewater stream by removing contaminants that float and heavy contaminants that settle to the bottom; and an ozone treatment system.

Abstract: A wash pad and wash fluid containment system upon which items such as vehicles or equipment are positioned and supported for collecting wastewater occasioned when washing the items, the system having various combinations of the following: a central trench, left and right side wash pad sections positioned on opposite sides of the central trench, the left and right side wash pad sections preferably being of identical configuration and interchangeable, each side wash pad section having a sloped surface for directing wastewater toward the central trench; a partial side wall enclosure assembly disposed about an outer perimeter of three sides of the wash pad; integrated pressure washer system mounted on the rear wall; a retractable cover assembly including a tarp wrapped on a roller mounted on the rear wall; side wall extension system extending above the side walls including a frame and tarp sections hanging on the frame.

Abstract: A parts washer is disclosed. The parts washer includes a housing that has a washbasin defining an inner cavity and chargeable with a volume of fluid. A spray tube is rotatably positioned within the housing and has an axis of rotation. The spray tube is configured to define a volume of rotation as it rotates about its axis of rotation. A support structure configured to support parts to be washed is positioned within the housing and is substantially within the volume of rotation of the spray tube. The parts washer further includes a pump connected to the spray tube. The pump delivers fluid under pressure to the spray tube. The spray tube includes a plurality of outlets configured to direct fluid towards parts to be washed on the support structure and at least one outlet configured to direct fluid in a direction to cause fluid-propelled rotation of the spray tube about its axis of rotation.
