TDA RESEARCH, INC. — Department of Defense STTR Phase I: AF20C-TCSO1

Description

In parts of the world access to potable water is limited, and therefore closed-cycle technologies for water reuse could dramatically reduce the logistical demands on potable water transportation to military bases in remote or arid locations. A typical estimate is that each person requires a minimum of about 15 L of water per day; sustaining a base that includes water for modern facilities for laundry, cooking, bathing, etc. requires even more. The Air Force is interested in an energy-efficient system to supply potable water (meeting all regulatory standards) for long-term operation in an area with limited or no external access to water. In this STTR effort TDA Research, Inc. (TDA) and the University of Texas at San Antonio (UTSA) will design a closed-cycle system able to be powered by military generators and only requiring 10% makeup water (of any source, including salt water). This technology will have commercial interest in the civilian market as well, particularly for remote, arid regions that have difficulty supplying potable water. With the duration and severity of droughts increasing, a closed-cycle system for water reuse will increase access to potable water for both military and civilian communities across the world.
