The Environmental Technology Verification program has been contracted to NSF International by the EPA. Through this program NSF International and EPA approve a detailed test plan designed to validate performance claims. In this case we will be testing the ability of the Expeditionary Unit Water Purifier (EUWP) to produce 100,000 gallons per day of water meeting EPA safe drinking water standards from any source. The test source will be the secondary treated wastewater from the City of Gallup, NM. The EUWP uses screening, Koch Ultrafiltration and Reverse Osmosis with optional coagulant addition, chlorination, de-chlorination. Extensive water analyses will be performed on the raw water at high and low loading periods, UF filtrate, backwash, RO permeate and concentrate to determine organic, inorganic, and biological components. All aspects of performance will be evaluated for a period of 6 weeks during the summer of 2006.

ETV Testing is important to provide acceptance for this type of equipment to be used for emergency response actions. It will also provide valuable data on the ability of UF and RO technology to produce safe drinking water from wastewater.
