Abstract:
The present invention addresses the problem of providing mineral water and a salt mixture that can be used for applications where a trace constituent composition is important, and a production method therefor. The problem is solved by an evaporation solid-liquid separation method for carrying out evaporation solid-liquid separation of sea water into a salt mixture and mineral water, characterized in that, at least during a main evaporation solid-liquid separation step, the temperature of the sea water is maintained at a temperature between 25°C and 60°C and the pressure in a vessel is maintained within 1-20 kPa using a pressure reducer, and by a salt mixture and mineral water produced by the production method.
