An apparatus and method is disclosed for recycling contaminated industrial liquids. In the preferred embodiment, a conventional, medium-sized “van”type of truck houses, transports and powers a dual-loop assembly. A filter-loop assembly receives and stores recycling liquid in a waste liquid holding tank. The liquid is pumped through a pasteurizing heater and a separating centrifuge and back to the tank. Filter-test valves in the filter-loop enable testing to determine desired heating and separation. When flow-rate adjustments produce satisfactory heating and separation, the recycling liquid is directed through a cooler, out of the filter-loop and into an additive-loop assembly where the liquid is pumped from a clean liquid holding tank, by additive compound injections, and back to the clean tank. Additive-test valves in the additive-loop enable testing to determine required quantities of specific additive compounds. When tests indicate satisfactory levels of the compounds, the recycling liquid is directed out of the additive-loop assembly and out of the system. The filter and additive test valves enable periodic testing during recycling to insure consistency. If the recycling becomes inadequate, the filter-loop and/or additive-loop is closed until changes in the flow-rate or additive injection rates again produce satisfactory recycling.

A method of recycling contaminated liquid, which comprises: a. pumping recycling liquid through a filter-loop assembly that includes the steps of: i. adjusting the flow-rate of recycling liquid as it is pumped through the filter-loop assembly; ii. heating the flow-rate adjusted recycling liquid; iii. passing the heated recycling liquid through a mechanical separator; iv. cooling the separated recycling liquid; v. testing the separated recycling liquid to determine the quality of separation; and b. pumping the recycling liquid from the filter-loop assembly through an additive-loop assembly, when the quality of separation of the recycling liquid achieved by the filter-loop assembly step is adequate, that includes the steps of: i. testing the separated recycling liquid to determine what additive compounds are needed, and the quantity of any said additive compounds needed, to achieve desired recycling; ii. adjusting additive metering valves to inject quantities of additive compounds into the separated recycling liquid determined by the testing; iii. directing the separated recycling liquid to flow by an additive suction “T”-joint; iv. directing additive compounds through the adjusted additive compound metering valves, and through the additive suction “T”-joint into the separated recycling liquid; v. directing the separated, additive-injected recycling liquid to flow out of the additive-loop assembly.
