Abstract:The application of advanced membrane processes for drinking water treatment is hampered by the management of the concentrated membrane residuals. This byproduct is typically treated as waste, with the associated costs for disposal. In this study we tested electrolysis as an approach to recover potentially useful products from this waste stream, mitigating its cost of disposal. Aqueous solutions of Mg(NO 3 ) 2 , MgCl 2 , or MgSO 4 similar in concentration to those measured in typical membrane concentrates were … 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.
