Abstract

The present invention relates generally to an environmentally sensitive mobile cleaning system, and more specifically relates to a closed loop water recirculation system for high or ultra-high pressure mobile cleaning apparatus. The system includes a water tank sized to contain 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.
