Explore: Reverse Osmosis

Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies

Osmosis (/ɒzˈmoʊsɪs/, US also /ɒs-/) is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a

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

Forward osmosis (FO) is an osmotic process that, like reverse osmosis (RO), uses a semi-permeable membrane to effect separation of water from dissolved

the solutes including salt and other contaminants. In the process of reverse osmosis, water is purified by applying high pressure to a solution and thereby

The primary processes and technologies used in desalination include reverse osmosis, multi-stage flash distillation (MSF), and multi-effect distillation
