PURPOSE:To produce mineral water in a short time by submerging a vessel provided with an underwater pump, putting the underwater pump into operation, and circulating the water to pass repeatedly through active material provided to the suction side of the underwater pump. CONSTITUTION:The underwater pump 7 is provided in the vessel 6 and the active material 10 (for example, rare element ore, mineral ore, perlite) are provided to the suction side of the underwater pump 7. An expansion pip 11 is provided to the water discharge opening 8 of the vessel 6 so that the top end 11 of the expansion pipe 11 is located above the water surface. Then, the vessel is put into water to circulate the water through the active materials 10 to make mineral water. As a result, mineral water is produced in a short time and also the water is always kept in the fresh. |
