Claim 5:
6. A system for producing a concentrated waste fluid, comprising:
a concentrator, the concentrator selected from a group consisting of an evaporator and a distillation system;
a separator disposed downstream of the concentrator;
a feedback sensor, wherein the feedback sensor is a total dissolved solids (TDS) sensor disposed in a waste stream outlet conduit of the separator, and a closed loop controller in communication with the TDS sensor, the closed loop controller configured to react to a feedback generated by the feedback sensor by causing an amount of fuel provided to the concentrator to be varied via a fuel controller, wherein the concentrator includes a direct steam generator and a heat source for the direct steam generator is controlled by varying the amount of fuel provided to the concentrator via the fuel controller in relation to a TDS associated with a concentrated waste fluid that forms a slurry waste stream at the waste stream outlet conduit of the separator, wherein the
waste stream outlet conduit is configured to convey the concentrated waste fluid that forms the slurry to a storage tank or down a disposal well.
