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.

1. Apparatus for washing an object having a contaminant and for recovering the contaiminant contaminant, comprising:a floor to support said object; means for flowing a washing agent over said object; a basin mounted below said floor for receiving said washing agent and said contaminant, the basin including a plurality of baffle walls to define a plurality of outer chambers positioned at the edges of the basin and at least one inner chamber surrounded by the outer chambers, the floor having at least one channel for directing said washing agent and contaminant into the outer chambers; means for circulating a slurry of said washing agent and said contaminant from the outer chambers to the inner chamber; at least one contaminant separator located in the inner chamber of said basin; means for filtering the contaminant in said slurry to produce a cleaned slurry flow; and means for recirculating the cleaned slurry flow into one of the outer chambers of said basin.
