Electrochemically mediated seawater desalination.
With global demand rising faster than availability, fresh water is quickly becoming a limited resource. In fact, the United Nations estimates one third of the world s population is living in water-stressed regions, and by 2025 this number is expected to double. Seawater desalination is an attractive solution to this problem because seawater accounts for more than 97% of the world s water supply...
متن کاملSustainable Seawater Reverse Osmosis Desalination as Green Desalination in the 21st Century
Seawater reverse osmosis desalination (SWRO) requires less energy compared with the distillation method and thus is an important technology except Middle Eastern countries whereenergy costs are higher. Recently, even Middle Eastern countries where the distillation method is still a major technology, have begun adopting the RO method in new desalinationplants in line with government ...

متن کاملBoron removal in seawater RO desalination
In the seawater desalination field, WHO requires the boron concentration in drinking water to be below 0.5 mg/l, and this requirement has affected SWRO process design, because of the difficulty to achieve such low boron concentration. In order to overcome this problem, a new SWRO membrane element, which had higher boron rejecting performance, was developed. This new SWRO membrane element exhibi...
متن کاملSeawater Desalination by using Nanofiltration (NF) and Brackish Water Reverse Osmosis (BWRO) Membranes in Sequential Mode of Operation
In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...
