Abstract
A process of removing contaminants and concentrating wastewater includes delivering wastewater from a source of wastewater to a hydrogen sulfide removal device, mixing an oxidant with the filtered wastewater in the hydrogen sulfide removal device to produce a hydrogen sulfide lean effluent, delivering the hydrogen sulfide lean effluent to a direct contact concentrator, and evaporating a portion of the hydrogen lean effluent in the direct contact evaporator to produce a slurry and an exhaust gas.
