Abstract
System and method of treating waste water includes: receiving waste water at a first pressure and a first temperature, the waste water comprising dissolved solids and VOCs; pressurizing the waste water to a second pressure; preheating the pressurized waste water to a second temperature to produce distilled water and pressurized/preheated water; heating the pressurized/preheated to a third temperature to produce pressurized/heated water; removing dissolved solids from the pressurized/heated water, by an evaporator operated at a third pressure less than the second pressure, to produce steam and brine water; and crystallizing the brine water, by a crystallizer operated at a fourth pressure greater than the second pressure, to produce a solid mass waste product and steam. Steam produced by the crystallizer, at the fourth pressure and a fourth temperature, is a heat source for the preheater and/or heater, and steam produced by the evaporator is a heat source for the crystallizer.
