Water desalination processes separate dissolved salts and other minerals from water. Feedwater sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor), electric potential, and concentration to overcome natural osmotic pressures and effectively force water through membrane processes. As such, the technology is energy intensive and research is continually evolving to improve efficiency and reduce energy consumption.
The project includes the planning, design and construction of a seawater desalination system to meet the demand of water on the Islands, especially features that are floating, self-contained and cover the energy needs in an environmentally friendly manner, utilizing renewable energy sources – primarily wind and, in the alternative, solar energy. Putting wind turbines on the floating construction and together with the desalination plant offers a number of advantages, such as: reduced cost of connection units. Capacity of the unit away from residential areas. Ability to move the unit depending on seasonal demand. Reduced implementation costs since even large units can be built in places with infrastructure (shipyards) and transferred to operating parts which do not have necessary infrastructure for their construction
