ABSTRACT:
An apparatus for washing and recovering a contaminant from an object. A washing agent flows over the object, and the washing agent and contaminant are received in a basin. A slurry of the washing agent and contaminant are circulated through at least one separator and one filter to produce a cleaned slurry flow. The cleaned slurry flow is recirculated into the basin. A first pump which is used to flow the washing agent over the object has a supply port and a pressurized output port. A pressurized fluid supply is coupled to a variable regulator with a variable pressure output. A second pump driven by the variable pressure output impels the washing agent into the supply port of the first pump.
