Project: Enhanced Brine Concentration Design Pilot Project

Description: The Enhanced Brine Concentration Design Pilot Project (Project) includes the construction, purchase, installation, and testing of a 100 gallon per minute (gpm) AquaSelTM system, which was successfully tested at a laboratory bench-scale of 8 gpm using concentrate from EMWD's Menifee Desalter. To prove the scalability of the technology, the Project capacity of 100 gpm will be operated in two phases of 6 months each. The first phase will operate the system under similar conditions to the 8 gpm pilot system and test an improved design of the system precipitator. The second phase will operate the 100 gpm system under optimized conditions for a period of 6 months. The 100 gpm Project will enable EMWD to seamlessly move to a full-scale 400 gpm module system with four trains. The full-scale project would expand the desalination capacity to produce 15,000 AFY of potable supply and increase RO concentrate production proportionally. The full-scale project would reduce the volume of concentrate from 2.3 mgd to about 0.5 mgd, saving EMWD about $500,000 per year in disposal costs.

Reference Number: 3860-P01-328

Implemented By: Eastern Municipal Water District

Objective: Improve local water supply reliability through advanced treatment of the brine from RO treatment of saline raw water. The Design Pilot will construct, operate, and evaluate full-scale innovative equipment that was found to be promising through a small-scale "lab bench" type analysis. This pilot will determine operability and operating costs for full-scale implementation.
