  • Patent number: 5704989
    Abstract: A method for removing contaminants from a surface such as pavement using a portable closed-loop system which is transported to the location to be cleaned by a vehicle. The method includes storing a volume of fluid in a clean tank, pumping the fluid to a cleaning head, blasting the surface to be cleaned with the fluid, suctioning the contaminants from the surface, removing suspended and colloidal contaminants, removing hydrocarbons, and returning this fluid to the clean fluid tank for recirculation through the system.

  • Patent number: 5469597
    Abstract: The present invention relates generally to an environmentally sensitive cleaning system, and more specifically relates to a closed loop high pressure cleaning system for cleaning surfaces without dislodging contaminants into the storm water drain or to the environment. The present invention is directed to a method and apparatus that satisfies this need. The apparatus comprises an established volume of fluid sufficient to circulate through the system, a pump to pressure the fluid to a cleaning head, a vacuum system to return the contaminated fluid to the system, and a filter means to remove the contaminants from the fluid so that clean fluid can be reintroduced to the cleaning head. The method comprises the steps of increasing the pressure of a fixed volume of fluid in a closed-loop system, jetting or blasting the surface with the pressurized fluid, vacuuming the blasted fluid into the system, and removing the contaminants from the fluid.
