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.

As it flows back through the stages the water is now called brine, to distinguish it from the inlet water. In each stage, as the brine enters, its temperature is above the boiling point at the pressure of the stage, and a small fraction of the brine water boils ("flashes") to steam thereby reducing the temperature until an equilibrium is reached.
A solvent whose solubility varies with temperature is added to saltwater. At room temperature the solvent draws water molecules away from the salt. The water-laden solvent is then heated, causing the solvent to release the now salt-free water. [164] It can desalinate extremely salty brine up to seven times as salty as the ocean.
Modern Water's containerised forward osmosis desalination plant at Al Khaluf, Oman Forward Water Technologies Industrial FO Installation at Terrapure-2019. Desalinated water can be produced from the diluted draw / osmotic agent solution, using a second process.
The median cost of producing desalinated water is "in the neighborhood of $2,000 an acre-foot," he said. Michelle Peters, technical and compliance manager for Poseidon Water, walks in the reverse ...
A potential difference is applied between both channels of flowing carbon slurries, the so-called flow electrodes, and water is desalinated. Since the carbon slurries flow, the electrodes do not saturate and therefore this cell design can be used for the desalination of water with high salt concentrations as well (e.g. sea water, with salt ...
Many different types of nanomaterials or nanoparticles are used in water treatment processes. Nanotechnology is useful in regards to remediation, desalination, filtration, purification and water treatment. The main features that make nanoparticles effective for water treatment are More surface area; Small volume
The compression is mechanically powered by something such as a compression turbine. As vapor is generated, it is passed over to a heat exchanging condenser which returns the vapor to water. The resulting fresh water is moved to storage while the heat removed during condensation is transmitted to the remaining feedstock.
