  • What Does Reverse Osmosis Remove? - The Water Geeks

    2019-10-2u2002·u2002Viruses & Bacteria – Reverse osmosis removes these two types of contaminants to a high degree but even just a small amount passing through can pose problems to health. Where with contaminants like chlorine, a fractional amount doesn't pose much of a health risk, with bacteria and viruses, this just isn't true.

  • Reverse Osmosis - an overview

    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.
