ABSTRACT:
A process for removing trace amounts of water soluble organic and inorganic substances dissolved in a water supply from the water supply includes the steps of flowing water from the water supply including trace amounts of the water soluble substances dissolved therein adjacent to and in contact with one side of a semipermeable barrier within a chamber, inducing evaporation of the trace amounts of the water soluble substances from the flowing water and permeating the evaporated water into the barrier. The water soluble organic and inorganic substances are removed from the barrier and chamber thereby further inducing evaporation and removal of the water soluble substances from the flowing water. The flowing water free of trace amounts of the water soluble organic and inorganic substances are also removed from the chamber.
