Abstract
A method for substantially removing both alkaline earth metal cations and dissolved acidic gases from a water source contaminated therewith to produce a substantially nonscaling and noncorroding water supply therefrom. The method includes contacting the contaminated water source with an ion exchange resin to substantially remove the metal cation contaminants contained therein and produce a demineralized intermediate effluent having a pH of less than about 3.5. The demineralized intermediate effluent then is stripped of the acidic gas contaminants dissolved therein and the pH of the stripped effluent adjusted to a value in the range of from about 9.0 to about 10.0.
