1. A system for treating a biologically contaminated water stream comprising:
a flash vessel configured to receive a biologically contaminated water stream and to separate steam from liquid in the biologically contaminated water stream;
a blower configured to receive separated steam from the flash vessel and compress the separated steam to produce compressed steam, wherein the blower is configured to add the compressed steam into the biologically contaminated water stream;
a circulation pump configured to receive separated liquid from the flash vessel and to pressurize the separated liquid into a circulation stream;
a preheater exchanger configured to receive treated water from the circulation stream and preheat the biologically contaminated water stream; and
a pressure drop device configured to lower the pressure of the biologically contaminated water stream prior to receipt by the flash vessel;
wherein the system is configured to return all of the steam formed in the flash vessel back into the flash vessel.
