  • The early history of reverse osmosis membrane

    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.

    The pressure being applied at this moment is equal to the osmotic pressure. If the pressure is increased, the flow reverses and the solvent flows through the membrane in the opposite direction, that is, from the side of the more concentrated solution to the side with the more dilute solution. This process is called RO.
