  • Seawater Reverse Osmosis Desalination - WaterCore

    2020-11-23 · Reverse Osmosis desalination applied to seawater is the most cost-effective system capable of converting seawater into drinking water in one single pass. Considering that Australia’s surrounding Oceans have an average salinity of 31 g/l, reverse osmosis desalination plants are remarkably cheaper to build and maintain than the old heat distillation processes.

  • Sea Water Reverse Osmosis - an overview |

    Reverse osmosis is a widely utilised membrane technology for seawater desalination. The basic concept of Sea Water Reverse Osmosis (SWRO) is to utilise a semi-permeable membrane where most of the dissolved species are rejected while water permeates it. Normally, water spontaneously diffuses through a semi-permeable membrane from a dilute solution to a concentrated solution.
