Abstract:In this study, we evaluated the efficiencies of chemical cleaning agents for the removal of foulant and related the changes of membrane surface properties to the flux recovery in forward osmosis (FO) membrane process. Commercially available chemical cleaning agents were added and processed according to the protocols of reverse osmosis (RO) membrane processes into two steps-acid treatment, then base treatment, and the flux recovery and membrane surface properties were tested in FO mode. The flux of the fouled m… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
