  • Reverse osmosis systems in industrial processes

    Reverse Osmosis can be used to produce the water needed in the initial part of the process and also at the end of the process where the wastewater can be processed again using RO. Once the water is cleaned and the waste products removed and disposed of correctly rather than just flushed away, it can then be reused in the production process ...

    2017-7-24u2002·u2002Reverse Osmosis is capable of removing up to 99%+ of the dissolved salts (ions), particles, colloids, organics, bacteria and pyrogens/pathogens from the feed water (although an RO system should not be relied upon to remove 100% of bacteria and viruses). Reverse osmosis removes impurities by two distinct mechanisms.

  • 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.
