Potable water is one of the Army and Marine Corp's most basic logistics requirements, particularly in arid environments. The core technology in the Army and Marine Corp fielded tactical water purification units is reverse osmosis. New integrated membranes systems are under development combining membrane pretreatment with reverse osmosis. While the current systems have provided the Army with the capability to purify any source water with sufficient quality and quantities to support deployed troops, improvements are needed in membrane technology and systems to reduce the size and weight of the systems, reduce power, improve resistance to fouling, and improve rejection of potential chemical threat agents. The U.S. Army, Office of Naval Research, and Defense Research Project Agency are conducting collaborative research efforts to develop new membranes, new pretreatment technology, and new membrane system concepts to address the limitations of current technology for military water purification applications.
