Project TitleSolar-Powered Water Desalination
Track Code2013-030
Short Description

The University of Texas at El Paso seeks a licensing partner for a solar powered distiller using a novel condensation method.As compared to
reverse osmosis, the distiller is cost effective and produces distilled water.


The distiller uses a novel countercurrent flow of air and water. Air flow within the system is controllable for optimal water condensation rates. For the day cycle, a tank filled with brackish water is used as the source feed for the first effect floor circulation and condenser chill fluid. The Multi-Stage Flash uses brine recycle for maximum re-use of solar energy. For the night cycle, hot water from the day cycle is cooled producing distillate and cooling the water for use the next day.  As compared to reverse osmosis, the distiller is cost effective and produces distilled water. Patents issued and pending.
