REVERSE OSMOSIS DESALINATION

Reverse osmosis (RO) desalination is a method of producing fresh water from seawater by a process similar to filtration, rather than by traditional evaporative distillation. A semipermeable membrane allow water molecules to pass through while blocking the passage of most other ions. The qualities of RO which make it attractive for marine and naval applications are its ability to operate on electric power alone, requiring no heat source; its comparatively low system weight to other methods of freshwater production at sea; and its ability to operate automatically, requiring minimal operator attention. RO's high operational reliability has contributed to its gain in popularity in recent years. RO is used for freshwater production in commercial industry and surface ship applications worldwide. This paper discusses RO desalination and presents RO as an alternative to conventional distillation for naval and marine use.
