Purification stages inside the Purecom SMARTA station: - The membrane (reverse osmosis membrane) is a semi-permeable membrane with pores of 1/10,000 of a micron, through which water moves from a higher concentration solution (salty water) to a lower concentration (freshwater) due to the pressure generated by the pump. It is used to remove excess salts in the water, viruses, bacteria, and heavy metals. - The 4-in-1 mineral filter contains active carbon granules, calcite, cross-linked polymer, and ceramic balls, which help ionize the water, remove ammonia and nitrates, improve taste, eliminate odor, and provide mineral water. It also works to increase the pH value of the water and balance the acidity and alkalinity of the water.
