| 摘要 |
The present invention is related to a desalination plant, comprising a sea water intake, a desalination unit comprising a reverse osmosis or a thermal desalination unit, a fresh water outlet and a brine outlet, characterised in that it further comprises a salinity gradient power unit comprising a brine inlet, a seawater inlet and an effluent, wherein said brine outlet is connected to said brine inlet and said salinity gradient power unit is arranged to generate an electrical current.
The present invention is also related to a method for reducing the power consumption of a desalination plant providing fresh water and brine from sea water, comprising the steps of:
- providing a salinity gradient power unit,
- feeding said salinity gradient unit with brine from said desalination plant as high salinity feed and sea water as low salinity feed,
- generating an electrical current in said salinity gradient unit, and
- using said electrical current as an energy source for said desalination plant. |
