Does anyone have experience/data regarding Brine Energy Recovery devices (i.e. ERI turbo) used on Brackish Water feed (not Seawater). Is it cost effective for a brackish water feed water or 2 pass RO application?

The answer to your question depends on the expected life of the facility and the cost of electricity in your area. We included them in a brackish groundwater design near Phoenix but the project was ultimately shelved due to the housing market and the economy.

Thanks. What was your theoretical (since the project was shelved) pay back for this device. What was your operating pressure. Regards

I do believe that it could still be beneficil, especially if you are running at a lowish recovery (say 70%).....you will essentially transfer the energy from your concentrate stream into the feed flow, reducing the size of your HP pump by 30%.
