  • Reverse Osmosis - an overview | ScienceDirect

    Reverse osmosis (RO) is essentially a pressure-driven membrane diffusion process. In practice, RO membranes retain 95–99% of the dissolved solutes (organic and inorganic) from the feed stream into the concentrate, while the permeate can be considered as high-quality water. Therefore, RO is classified as a concentration process.
