1. An aqueous stream cleaning system, comprising:
a waste fluid pump in fluid communication with a waste fluid source and configured to expel a waste fluid stream;
a circulation pump configured to receive at least one of the waste fluid stream and a concentrated bottoms stream, and expel a circulation stream;
a primary heat exchanger configured to receive the circulation stream from the circulation pump, said primary heat exchanger having a plurality of heat exchange members that define an internal surface area for heat transfer from a pressurized distillate stream to the circulation stream;
an evaporation unit configured to receive a heated circulation stream from the primary heat exchanger, wherein a cooled distillate stream is formed when the heated circulation stream evaporates in the evaporation unit, and the concentrated bottoms stream is formed from a portion of the heated circulation stream that does not evaporate; and
a recirculation loop comprising a recirculation stream having an inlet from the waste fluid stream prior to the circulation pump, wherein the recirculation stream rejoins the waste fluid stream upstream of the inlet.
