At the same time, the above-described filtration mode also filters out beneficial minerals in the water, resulting in long-term use of these mineral-deficient waters, requiring supplementation of the beneficial minerals by other means. Therefore, the ultrafiltration membrane is used for purifying water subsequently, and mainly uses the sieving principle to separate macromolecular substances, colloid, bacteria, viruses and the like in the water through micropores on the membrane, and the pore diameter of the ultrafiltration membrane is generally between 0.01 and 0.1 micrometer, so that large-particle pollutants can be effectively removed, and mineral substances and smaller ions are allowed to pass through. Therefore, ultrafiltration membranes are often used for retaining beneficial minerals in water, but ultrafiltration membranes cannot filter small molecular substances (such as heavy metal ions and soluble salts), so that the ultrafiltration membranes focus on basic purification, and the minerals in the drinking water after the filtration of the ultrafiltration membranes still cannot be kept balanced.
