Abstract

System and method of treating waste water includes: receiving waste water at a first pressure and temperature, the waste water comprising dissolved solids and VOCs; pressurizing, by a pump, the received waste water to a second pressure greater than the first pressure; preheating, by a preheater, the waste water to a second temperature greater than the first temperature producing distilled water; further heating, by a condenser, the pressurized/preheated waste water to a fourth temperature greater than the second temperature; still further heating, by a heater, the pressurized/further heated waste water to a third temperature greater than the fourth temperature; and removing, by a flash evaporator, dissolved solids from the pressurized/heated waste water by evaporation producing steam and brine water, the brine water having a TDS content greater than a TDS content of the received waste water. The brine water may be crystallized to a solid mass.
