Abstract
The invention is a water recovery system that utilizes waste heat and a moving air stream to recover water with minimal use of energy and without the need to move water through filtration devices. The invention may be used for recovery and reuse of water for a wide range of emergency back-up, environmental, industrial, and mission-oriented purposes.
Claims6
A water recovery apparatus comprised of:
- a component for generating a moving air stream with sufficient speed, pressure, and volume to transmit heat and water vapor;
- a waste heat component for heating said moving air stream;
- a a heat conduit 12 coupled to a detachable drying chamber 14 having an open surface and containing a quantity of waste material having a recoverable water content, said waste material selected from the group consisting of waste, waste water, brine, sludge or other waste materials having recoverable water content, wherein said waste material forms a heating interface with said moving air stream;
- said drying chamber being coupled to an evaporation chamber 16 for utilizing aid waste heat to efficiently extract water from said waste material without losing heat to the environment, a cooling interface to reduce the temperature of said moving air stream as said moving air stream moves across said cooling interface;
- and a condensate collection area wherein said apparatus can recover water using less than 40 watt-hours of energy per gallon.
