PURPOSE:To produce clear potable water which contains mineral components and has taste by adding pulverous powder of quartz porphyry, etc. to clean water and suspending the same, then subjecting the suspended liquid to a permeation treatment by a tubular type ultrafilter membrane. CONSTITUTION:Minerals such as quartz porphyry and coral rock reef which are ground to pulverous powder and added to the clean water and are suspended; thereafter the suspended liquid is subjected to the permeation treatment by the tubular type ultrafilter membrane. The clear potable water which contains the mineral components and has taste is thus produced. The formation of 'slime' formed on the surface of the minerals is prevented by blowing a proper amt. of ozonized gas to the water in the stage of cleaning up the water by the minerals, by which the decrease in the cleaning-up power of minerals is prevented. The sanitary and clear potable water which contains the mineral components and has taste is thus produced. |
