Reverse osmosis process and applications | Condorchem Envitech

Definition of reverse osmosis. Reverse Osmosis (RO) process consists of generating an aqueous solution with a low salt content from another aqueous solution that has a high salt content, via a water-permeable membrane.. It is the technology used to produce desalinated water from seawater. Just as in MF and UF, the driving force for achieving the separation of the salt is caused by a difference
