Lightweight, Hand-Operated Brackish Water Purifier

Abstract

In response to a need expressed by US Military personnel operating in coastal areas, a lightweight, hand-operated brackish water purifier has been developed. This system utilizes a reverse osmosis cellulose acetate membrane for desalination. T total of 15 brackish water purifier units were fabricated and tested. Design and performance goals were met. The unit weight and volume is 11 lbs. and 0.3 cu. ft. Performance goals were 250 cc of potable water per minute and a salt rejection of 90% based on a brackish water salt concentration of 5,000 ppm. Pumping input is 0.12 HP. A seawater unit was also fabricated, which required that the water be pumped through twice. Design configuration the same as above. It provides potable water at 150 ppm from seawater concentration of 35,000 ppm.
