Abstract:
1. A method of producing lime water and remineralizing water comprising: a. deionising dilution water by membrane filtration, distillation or an ion exchange resin; b. mixing silicate ions with the deionised dilution water at a silicate ion injection site to produce a silicate ion-water mixture; c. after mixing silicate ions with the deionised dilution water and downstream from the silicate ion injection site, mixing milk of lime with the silicate ion-water mixture in a saturator to form lime water; d. precipitating solids in the lime water, wherein the precipitation is caused by the addition of silicate ions and milk of lime to the deionised dilution water; e. settling precipitated solids to form sludge in the saturator; f. discharging sludge formed in the saturator; and g. remineralizing water to be treated by mixing carbon dioxide and the lime water into the water to be treated.
