Abstract

A steam stripping process for softening water comprises contacting said water with steam to bring said water to a temperature of at least substantially 190 °C, to strip CO2 from said water and to cause the precipitation of Ca++ and/or Mg++ from said water.
Subsequently sufficient alkaline material is added to bring the pH of said stripped water to at least substantially 10. Thereafter, precipitated Ca++ and/or Mg++ is separated from said water.
