抄録

The new RO seawater desalination system for cost and energy saving has been developed. The newly developed “Brine Conversion Two-stage RO Seawater Desalination System” uses less energy than the conventional system to produce the same amount of fresh water. This system produces more fresh water from the concentrated water (salt concentration 5.8%, produced under 6.5 MPa pressure), which was exhausted to the sea in the conventional system.<BR>The new type membrane, which can be operated in conditions of high-pressure (9.0 MPa) and high concentration (5.8%), was developed and its performance of seawater desalination have been proved to be in good conditions.
