As the potential application of brackish water desalination increases, efforts to improve
its water recovery are becoming increasingly important. Concentrate management
(especially for inland applications) is often the decisive factor that determines the
viability of a desalination project because of regulatory, environmental and economic
issues. Currently the recovery from conventional configurations and application of
desalting processes (including reverse osmosis (RO), electrodialysis reversal (EDR),
and thermal evaporation processes) is limited, and 20 to 50 percent of the feed stream
is wasted as concentrate. This study presents a hybrid approach employing
membrane based treatment steps to improve water recovery of brackish water
desalination. The study is funded through Awwa Research Foundation (Project #3030:
Desalination Product Water Recovery and Concentrate Volume Minimization). Includes 30 references.
