Reverse Osmosis Membranes

The seawater desalination facilities by reverse osmosis membranes in the world are reviewed. The largest seawater desalination facility using reverse osmosis started its operation at Chatan water purification plant in Okinawa prefectural water works. The high-efficiency seawater desalination technology which improves the recovery ratio of fresh water up to 60% developed by a manufacturing company of reverse osmosis membranes in Japan is explained. Finally the state of the art of desalination technology development using reverse osmosis membranes is discussed.

Reverse Osmosis Membranes

This article shows the optimization of the reverse osmosis process in seawater desalination plants, taking the example of the Canary Islands, where there are more than 320 units of different sizes, both private and public. The objective is to improve the energy efficiency of the system in order to save on operation costs as well as reduce the carbon and ecological footprints. Reverse osmosis membranes with higher surface area have lower energy consumption, as well as energy recovery systems to recover the brine pressure and introduce it in the system. Accounting for the operation, maintenance and handling of the membranes is also important in energy savings, in order to improve the energy efficiency. The energy consumption depends on the permeate water quality required and the model of the reverse osmosis membrane installed in the seawater desalination plant, as it is shown in this study.
