Santa Ana Country Club Groundwater Desalination Project

Santa Ana, CA

PACE designed a packaged colored and brackish groundwater treatment system using reverse osmosis (RO), including RO water quality modeling, economic evaluation of the opportunity to reduce gypsum addition and excessive leaching of salts, consulting on system configurations, and desalination system design. Phase II included a granular activated carbon (GAC) pre-filtration system, which reduces organic fouling of the desalination system.

PACE has been monitoring water quality and system performance, including color, turbidity, sulfide, total and free chlorine, monochloramine, ammonia, nitrate, total and calcium hardness, total alkalinity, chemical oxygen demand, silica, etc. In addition, PACE has provided operation assistance, timely troubleshooting, and investigation of system performance to maximize water production and reduce excessive head loss due to organic and biofouling. The system was developed to use recycled water through the Green Acres Recycled Water Delivery System. The potential increased use of recycled water to Santa Ana Country Club will increase revenue and water recycling in general, and may be a pilot for on-site polishing of salts at project sites.

Key Features:

• RO water treatment
• GAC pre-filtration system
• Wellhead water quality testing
• Non-potable water supply
• Instrumentation & Controls
