    en.wikipedia.org/wiki/Reverse_osmosis_plant

    Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination , wastewater treatment , concentration of contaminants, and the reclamation of dissolved minerals.

    en.wikipedia.org/wiki/Electrodeionization

    Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...

    The ideal water potential between fresh water (right) and sea water (left) corresponds to a hydraulic head of 270 metres. Pressure retarded osmosis (PRO) is a technique to separate a solvent (for example, fresh water) from a solution that is more concentrated (e.g. sea water) and also pressurized.

  7. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    The most common means for removing water hardness rely on ion-exchange resin or reverse osmosis. Other approaches include precipitation methods, such as fluidized bed pellet softening, [6] and sequestration by the addition of chelating agents. Distillation and reverse osmosis are the most widely used two non-chemical methods of water softening.
