RO Water vs Alkaline Water

Reverse Osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other dissolved substances, such as, impurities and hard minerals in the water source. The membrane uses osmotic pressure to reject these impurities as small as 0.0001 (i.e. one-ten-thousandth or 1⁄10,000) micron in size.
