Abstract
An oxidative evaporation process for treating waste water or other aqueous solutions containing organics or reduced forms of inorganics is described. The process relies upon excessive amounts of pressurized oxygen gas to both oxidize the solution and to increase the solution's evaporation rate. The oxidized liquid effluent from a reactor undergoes a series of flashing steps until a saturated solution is produced which readily crystallizes upon cooling.
