ADS Engineering provided electrical and instrumentation design for the California Valley Solar Ranch reverse osmosis membrane treatment plant and related systems. RO system is based on a single two-stage train with bag and cartridge filter in pretreatment, clean in place system, chemical feed and monitoring systems, finished water storage and brine disposal.

Project Highlights:

• Design plant low voltage distribution system for the reverse osmosis system, supporting systems and process building.
• Implementation of variable frequency drives.
• Design of plantwise control PLC system with redundant fiber optic communication data highway for the monitoring and control of on site plant systems.
• Instrumentation implementation.
• Design control and monitoring strategies include pretreatment system, acid addition, and cartridge filtration; membrane treatment including feedwater pumping, interstage pumping, reverse osmosis treatment, and associated membrane cleaning facilities; post-treatment including disinfection, chemical addition for water stabilization, and water storage.
• Provided alarm and historical monitoring and trending with the usage of iFIX historical.
• Implemented advanced algorithms for RO system and transfer pumping to provide flexible system control.
