NOVELTY - Treatment of a natural mineral water comprises coarse filtering 15-20 m3/hour underground mineral water in a multi-media filter having stone particle layer, manganese sand layer, volcanic stone layer, and coconut shell activated carbon layer with a thickness of 100-200 mm; fine filtering in a primary fine filter having a single layer graphene nanosheet, and a secondary fine filter containing 40-70 wt.% graphene oxide-superparamagnetic nanocomposite material, and 30-60 wt.% graphene-reinforced diatomite material, at 15-20 m3/ hour; carrying out ultrafiltration in a reverse osmosis membrane filter having a pore diameter of 0.001-0.02 um; and ozone sterilizing, and sterilizing with a disinfectant for 30-60 minutes. The disinfectant comprises 10-20 pts. wt. polyaspartic acid, 15-25 pts. wt. calcium aluminate, 15-20 pts. wt. tea leaves, 10-15 pts. wt. licorice, 10-20 pts. wt. honeysuckle, and 15-25 pts. wt. activated carbon. USE - Method for treating a natural mineral water. ADVANTAGE - The ultrafiltration by reverse osmosis removes water to dissolve the salts, colloids, microorganisms, and organic matters. The method has good filtering and water purification effect.
