Is one of the processes that makes desalination possible and can even produce energy.
Reverse osmosis is one of the processes that makes desalination (or removing salt from seawater) possible. Beyond that, reverse osmosis is used for recycling, wastewater treatment, and can even produce energy. Water issues have become an extremely pressing global threat. Reverse Osmosis (RO) desalination uses the principle of osmosis to remove salt and other impurities, by transferring water through a series of semi-permeable membranes. Thermal desalination uses heat, often waste heat from power plants or refineries, to evaporate and condense water to purify it. Desalination • The process of removing dissolved salts and other minerals from seawater to obtain water suitable for human and animal consumption, irrigation and other industrial uses• Two desalination methods: by thermal process (multi stage flash) or by membrane (reverse osmosis). Reverse Osmosis Desalination Process. The core process of desalination is the Reverse Osmosis Process. It consists of a High pressure pump followed by an Energy Recovery device and the Reverse Osmosis Membranes. Formally, reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a semipermeable membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

Reverse Osmosis (RO) is a modern process technology to purify water for a wide range of applications, including semiconductors, food processing, biotechnology, pharmaceuticals, power generation, seawater desalting, and municipal drinking water. (There are several other less frequent types of desalination methods and energy sources not discussed here.). Reverse osmosis is a process where pressure is used to push the water solution through a membrane, with the membrane preventing the larger solutes (the salt) to pass through. Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
