The effect of three important process variables (altering heating of feed liquid, chamber length, and carrier gas temperature) on energy needed to produce potable water from waters containing dissolved solids by an innovational minimum energy using heat and mass transfer device will be investigated. This device uses an inert carrier gas operating at near atmospheric pressure to evaporate water and then to condense these evaporated waters in such a way as to reuse the heat of vaporization by a factor possibly as high as 300. If successful in Phase I research, this device, made of inexpensive plastic materials, would be superior to all current processes.
