<P>PROBLEM TO BE SOLVED: To provide an artificial mineral water production method and its system which produce artificial mineral water by extracting and collecting commercial mineral material from various waste materials generated in various water treatment processes. <P>SOLUTION: When filtration processes in various water treatment apparatuses are regenerated, the amount of water consumption is greatly suppressed by selectively adopting a proper washing method, and substances useful for forming specific mineral components are extracted and collected. A reducing agent is mixed into the artificial mineral water, which protects the useful substances from an unnecessary precipitation, and enables cyclic use as artificial mineral components. Selection of sodium thiosulfate as the reducing agent enables supply of hydrogen sulfide, which is a mineral component, at the same time. Use of sodium ascorbate as the reducing agent, and addition of copper ions enable sterilization of the artificial mineral water at the same time. A commercial mineral material, which contains no easily oxidizable or reducible mineral material, in the various waste materials generated in the various water treatment processes is used as the artificial mineral component after forming hydrogencarbonates. <P>COPYRIGHT: (C)2007,JPO&INPIT |
