    en.wikipedia.org/wiki/Reverse_osmosis

    Brackish water reverse osmosis (BWRO) is the desalination of water with less salt than seawater, usually from river estuaries or saline wells. The process is substantially the same as SWRO, but requires lower pressures and less energy. [1] Up to 80% of the feed water input can be recovered as fresh water, depending on feed salinity.

    en.wikipedia.org/wiki/Reverse_osmosis_plant

    A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. 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 ...

    en.wikipedia.org/wiki/Wegener–Bergeron...

    The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron, and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.

  5. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    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).

  6. Osmotic pressure - Wikipedia

    en.wikipedia.org/wiki/Osmotic_pressure

    Osmotic pressure is the basis of filtering ("reverse osmosis"), a process commonly used in water purification. The water to be purified is placed in a chamber and put under an amount of pressure greater than the osmotic pressure exerted by the water and the solutes dissolved in it.
