EVALUATION OF SEAWATER DESALINATION PROJECTS
PROPOSED FOR THE MONTEREY PENINSULA
2.4 Seawater Desalination Vessel (Water Standard Company)
Project name:
Proponent(s):
Location:
Purpose:
Seawater Desalination Vessel
Water Standard Company
The seawater desalination vessel would be anchored in Monterey Bay,
likely less than five miles from shore. Seawater would be treated on
the vessel and delivered to CAW, and potentially to other customers as
well. Brine disposal would be made at the vessel.
To provide water to satisfy a range of potable water demands in the
Monterey Peninsula area and Northern Monterey County.
Production volume:
10 to 20 mgd (11,200 to 22,400 ac-ft per year) up to 85,000 ac-ft per
year
Key features: 1. Microfiltration pretreatment system that is planned to extend RO
membrane life
2. Potential use of biodiesel
3. Ship-based
4. Multiple depth intake system
5. Desalination facility
6. Post treatment facility
7. Gas turbines with steam cogeneration capability and catalytic
emissions treatment
8. Brine discharge is diluted and made at water surface
9. Treated water transmitted by barges or seabed pipeline
