Abstract
This project demonstrates at the pilot scale the economic and associated energy efficiencies of a technology to improve reverse osmosis (RO) recovery from 85 to 95 percent, which also reduces concentrate volume by two thirds. Utilities that are planning and/or implementing inland desalination facilities to access brackish water resources will benefit from the research, especially waters with problematic silica and/or barium concentrations.
