    Reverse osmosis systems offer a more advanced treatment process than carbon filtration only or entry-level pour-through pitchers. At the heart of the system is a reverse osmosis membrane that removes impurities as small as an atom. Drinking water passes through a series of sediment and carbon RO filters before and after the RO membrane to eliminate any unwanted tastes and odors and provide ...

  • 2.1 Desalination by reverse osmosis

    There are two types of membrane process used for desalination: reverse osmosis (RO) and electrodialysis (ED). The latter is not generally used in Latin America and the Caribbean. In the RO process, water from a pressurized saline solution is separated from the dissolved salts by flowing through a water-permeable membrane.
