Many regions of the world face the problem of saline water. Water desalination processes, which require significant energy consumption, are a common solution to produce drinking water. This study evaluated the influence of the following process operational parameters on the energy consumption of seawater RO systems: water salinity, permeate recovery ratio, membrane performance and feed water temperature. Optimal operational conditions for the theoretical minimum energy consumption were determined with experiments by varying water qualities and operational parameters. In order to further reduce energy consumption a RO system was integrated with a PV solar system and a pilot PVRO system was built and tested. The results obtained from this study indicated that even though a Solar PV system incurs a huge initial capital investment, it will yield significant benefits in the long run of the RO operational period
