Use of Subsurface Intakes for Seawater Desalination in Monterey, California

This paper describes the operational experience and water treatment results obtained from a 0.3 MGD desal demo plant that uses the following processes: subsurface intakes (for pre-treatment), cartridge filtration (for RO unit protection), RO, UV disinfection, pH adjustment and calcite contactors (for stabilization) and chlorination. The results obtained from the demo plant are critical to the design of a full-scale desal plant that has a capacity up to 9.6 MGD.
