ABSTRACT:
A method for preparing artificial thermal water suitable to be used as domestic thermal water. In order to prepare the thermal water, a plurality of chemical components are mixed with highly pure water at predetermined rates to prepare a thermal water solution having components similar to those of a natural sodium bicarbonated spring, a simple thermal spring, a carbon dioxide spring, a radioactive spring or a sulfur spring. Fresh water or city water passes in order through an activated carbon filter, a microfilter, a anion-exchange resin and a cation-exchange resin to prepare pure water. The thermal water solution is mixed with the pure water and heated to prepare the thermal water prior to distributing the thermal water to a bathtub.
