Abstract

PURPOSE: To prevent deposit of scale on the membrane so as to give membrane permeated water at high efficiency, by forcing CO2 to enter an aq. soln. contg. Ca2+ or Mg2+ at a pressure lower than working pressure, by pressurizing the soln. to the working pressure to dissolve the CO2 into the soln., then by permeating the soln. through a reverse osmotic membrane.
