A method for producing an ionized water product, comprising the steps of: introducing source water (120, 260) to an ionization system (100, 200) comprising first and second reaction vessels (106, 208, 216); passing the source water through a first valve (108, 206) that directs the source water into first and second streams; passing the first stream through the first reaction vessel (106, 208), wherein the first reaction vessel comprises a packed bed of solid calcium carbonate configured to dissolve calcium and carbonate ions into the first stream; passing the second stream through the second reaction vessel (106, 216), wherein the second reaction vessel comprises a packed bed of solid magnesium sulfate configured to dissolve magnesium and sulfate ions into the second stream; passing an output of the second reaction vessel through a second valve (108, 222), which directs the output of the second vessel into a first portion and a second portion; directing the first portion of the output from the second reaction vessel to a third reaction vessel (106, 230), wherein the first portion is a saturated magnesium sulfate output stream and wherein the third reaction vessel comprises a strongly basic anion exchange resin preloaded with bicarbonate ion and is configured to replace sulfate ions from the saturated magnesium sulfate output stream with bicarbonate ions to create a magnesium bicarbonate solution; directing the second portion of the output from the second reaction vessel to a first dosing mechanism (112, 226) that regulates the flow of the second portion; directing an output of the third reaction vessel to a second dosing mechanism (112, 236) that regulates a flow of the output of the third reaction vessel; and creating the ionized water product by combining a first ionized water stream output from the first reaction vessel, a second ionized water stream from the first dosing mechanism, and a third ionized water stream from said second dosing mechanism via a controller (114, 250) configured to automatically adjust ratios of the ionized water streams to produce the ionized water product having between about 10 ppm to about 40 ppm magnesium ions, about 10 ppm to about 40 ppm calcium ions, and about 40 ppm to about 90 ppm total of bicarbonate and carbonate ions. introducing source water (120, 260) to an ionization system (100, 200) comprising first and second reaction vessels (106, 208, 216); passing the source water through a first valve (108, 206) that directs the source water into first and second streams; passing the first stream through the first reaction vessel (106, 208), wherein the first reaction vessel comprises a packed bed of solid calcium carbonate configured to dissolve calcium and carbonate ions into the first stream; passing the second stream through the second reaction vessel (106, 216), wherein the second reaction vessel comprises a packed bed of solid magnesium sulfate configured to dissolve magnesium and sulfate ions into the second stream; passing an output of the second reaction vessel through a second valve (108, 222), which directs the output of the second vessel into a first portion and a second portion; directing the first portion of the output from the second reaction vessel to a third reaction vessel (106, 230), wherein the first portion is a saturated magnesium sulfate output stream and wherein the third reaction vessel comprises a strongly basic anion exchange resin preloaded with bicarbonate ion and is configured to replace sulfate ions from the saturated magnesium sulfate output stream with bicarbonate ions to create a magnesium bicarbonate solution; directing the second portion of the output from the second reaction vessel to a first dosing mechanism (112, 226) that regulates the flow of the second portion; directing an output of the third reaction vessel to a second dosing mechanism (112, 236) that regulates a flow of the output of the third reaction vessel; and creating the ionized water product by combining a first ionized water stream output from the first reaction vessel, a second ionized water stream from the first dosing mechanism, and a third ionized water stream from said second dosing mechanism via a controller (114, 250) configured to automatically adjust ratios of the ionized water streams to produce the ionized water product having between about 10 ppm to about 40 ppm magnesium ions, about 10 ppm to about 40 ppm calcium ions, and about 40 ppm to about 90 ppm total of bicarbonate and carbonate ions.
