Closed loop surface cleaning system

A closed-loop pressure cleaning system for cleaning a surface, comprising:

• a portable base;
• an uncontaminated fluid storage tank mounted on the portable base wherein the uncontaminated fluid storage tank includes a return port and a discharge port;
• a high pressure fluid jetting pump mounted on the portable base and having an inlet and an outlet wherein the inlet is connected by a clean water line to the discharge port of the uncontaminated fluid storage tank;
• a surface cleaning head including a means for jetting fluid against the surface to be cleaned mounted on the surface cleaning head, wherein the means for jetting fluid is connected to the outlet of the high pressure fluid jetting pump by a high pressure fluid line, and wherein the surface cleaning head further includes a means for suctioning any contaminants on the surface and any associated fluid, wherein the means for suctioning is mounted on the surface cleaning head;
• a contaminated fluid storage tank mounted on the portable base including a top, an intake port and a discharge pen wherein the intake pen of the contaminated fluid storage tank is connected to the means for suctioning by a vacuum line;
• a vacuum pump mounted on the portable base having a suction pen connected through the top to an interior of the contaminated fluid storage tank by a vacuum suction line;
• a contaminated fluid pump mounted on the portable base having an inlet and an outlet wherein the inlet is connected to the discharge port of the contaminated fluid storage tank by an input line;
• and
• a filtration system for filtering a contaminated fluid including at least two filters wherein one of said filters includes a means for removing hydrocarbons from the contaminated fluid mounted on the portable base wherein an upstream side of the filtration system is connected to the outlet of the contaminated fluid pump by a contaminated fluid pump discharge line and a downstream side of the filtration system is connected to the return port of the uncontaminated fluid storage tank by a clean fluid return line.
