Selective separation of mono- and multi-valent ions has important applications in water reuse, desalination, and salt production, by adjusting ion composition to meet product water quality requirements. In this study, we developed an innovative monovalent permselective cation-exchange membrane (CEM) CR671 by modifying normal grade membrane CR67 wit...

An algal wastewater treatment process was combined with a hybrid forward osmosis (FO) and reverse osmosis (RO) membrane system to treat urban wastewater, harvest algae for recovering energy and nutrients, and produce potable-quality water from primary settled wastewater. The technical viability of the coupled algal-membrane system was demonstrated ...
