Abstract Scope Nitrate contamination is a water pollution problem in the U.S. and globally. Mining and agriculture disperse nitrate into water supplies creating significant contamination in receiving waters. There is increased demand for new water technologies to meet new regulation and more exacting effluent standards. Standard chemical/physical water treatment technologies do little to aid in meeting effluent standards for nitrate and associated anions such as selenate and sulfate. The Winner Water Hydroflex system is an adaptable technology to remove nitrate, selenate and sulfate from waste water. Hydroflex includes solvent extraction loading, scrubbing and stripping with a strong base anion exchange solvent. Nitrate may be stripped as a strong solution of calcium nitrate using a milk of lime strip solution. The loading and stripping data from testing of Hydroflex on a waste water sample will be presented and discussed along with an economic model demonstrating the cost effectiveness of the technology.
