What are desalination plants?

  • A desalination plant turns salt water into water that is fit to drink.
  • The most commonly used technique used for the process is reverse osmosis where external pressure is applied to push solvents from an area of high-solute concentration to an area of low-solute concentration through a membrane.
  • The microscopic pores in the membranes allow water molecules through but leave salt and most other impurities behind, releasing clean water from the other side.
  • These plants are mostly set up in areas that have access to sea water.
