The Seawater Desalination Vessel: Better For The Environment Than Land-Based Options
Water Standard Company's Seawater Desalination Vessel (SDV) adapts proven processes that military and cruise ships have used for years and combines them with proprietary technologies that are in many ways an improvement over existing land-based desalination options.
The SDV is an ocean-going vessel with on-board desalination technology that can produce up to 300,000 cubic meters of drinking water daily. The vessel utilizes an intake system that will use cleaner water resources, farther from the shoreline and typically beneath the sunlight-penetration level where there is less marine life, as well as wellscreens to minimize marine life impingement and entrainment. It will also incorporate a dilution and discharge system designed to adjust the temperature and salinity of after-process concentrate.
These processes have minimal impact on marine life, and were developed specifically to preserve the ocean's ecological balance.
Additionally, the SDV offers numerous other benefits that differentiate it from land-based desalination, including:
- Energy efficiency. Rather than having to co-locate near power plants – a requirement in land-based desalination – the SDV can have on-board power generation with full emission controls.
- Reliability. Because the SDV generates its own power, it is not affected by outages, brownouts, or rolling blackouts.
- Mobility. Whereas hurricanes and tropical storms can threaten land-based desalination plants, the SDV simply moves out of the way with minimal operational disruptions.
- Speed to production. The SDV can begin providing fresh water within 18 to 24 months under normal circumstances and in some cases 12 to 14 months – generally faster than land-based plants.
- Minimal shoreline impact. The SDV can typically operate two to five kilometers offshore, so it has no environmental or aesthetic impact on the shoreline.
- Flexibility. Water Standard Company can custom-design contracts for individual or regional entities.
