Description:
The Expeditionary Unit Water Purifier (EUWP) is supported and deployed by NFESC, the TARDEC, and the USBR. The EUWP was deployed to Biloxi, MS after Hurricane Katrina to supply potable water to a hospital, using seawater from the Gulf of Mexico as the source water. The EUWP system was designed to produce potable water from almost any freshwater, wastewater or seawater source, with a capacity of 100,000 to 250,000 gallons per day depending on system configuration and water quality. The EUWP treatment system includes optional ferric chloride coagulation, ultrafiltration (UF) hollow-fiber membrane modules, and reverse osmosis (RO) modules containing thin-film-composite membranes (double-pass mode optional) with an energy recovery pressure exchanger. The treated water can be chlorinated and stored in a 20,000- gallon bladder tank prior to distribution.
