RO is the most common desalination process due to its efficiency compared to thermal desalination systems, despite the need for water pre-treatment. [39] Economic and reliability considerations are the main challenges to improving PV powered RO desalination systems. However, plummeting PV panel costs make solar-powered desalination more feasible.

Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. [1]
Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water.Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO).
Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options.

Carbon nanotubes are being investigated for use in desalination due to their ion exclusion properties. This is largely due to the unfavorable energy barrier that would have to be overcome in order to desolvate the ions, as the hydrated ions are often larger than the diameter of the nanotubes. As the diameter of the tube increases, larger and ...
Electrodialysis reversal (EDR) is an electrodialysis reversal water desalination membrane process that has been commercially used since the early 1960s. [1] An electric current migrates dissolved salt ions, including fluorides, nitrates and sulfates, through an electrodialysis stack consisting of alternating layers of cationic and anionic ion exchange membranes.
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions.
