Patent ID: 8677555

Claim:
A mobile system for using water to clean an organic spill from a contaminated hard surface, the mobile system comprising: a mobile platform operably mounted on wheels for movement across the contaminated hard surface, the mobile platform having a width; at least one clean water storage tank mounted on the mobile platform for storing the water; a cleaning hood operably mounted on the mobile platform such that the cleaning hood may be positioned immediately above the contaminated hard surface, the cleaning hood extending across substantially the entire width of the mobile platform; at least one heater compressor unit for heating water from the at least one clean water storage tank, compressing the water to at least 3,500 psi, and spraying the water through nozzles positioned within the cleaning hood, so that the water is directed onto the contaminated hard surface under the cleaning hood; a waste water storage tank mounted on the mobile platform, and isolated from the at least one clean water storage tank, so that no water from the waste water storage tank contaminates the water in the at least one clean water storage tank; a vacuum generator for generating a vacuum in the waste water storage tank; and wastewater lines extending between the waste water storage tank and the cleaning hood, so that contaminated water from the contaminated hard surface is drawn into the waste water storage tank, wherein the waste water storage tank is held in a constant state of negative pressure to prevent spillage.
