Biological activated carbon (BAC) is operationally a simple treatment which can be employed to remove effluent organic matter (EfOM) from secondary wastewater effluent (SWWE). Unfortunately, BAC removes only a limited amount of dissolved organic carbon (DOC). Thus, maximizing DOC removal from SWWE using BAC is a major concern in wastewater reuse. This study has investigated a hybrid system of BAC and Magnetic Ion Exchange Resin (MIEX(®)) for the enhanced removal of DOC. Performance of both BAC prior to MIEX(®) (BAC/MIEX(®)) and reverse (MIEX(®)/BAC) combination was evaluated in terms of DOC removal. The BAC/MIEX(®) showed much better DOC removal. This is because microbial activity in the BAC bed converted MIEX(®) non-amenable DOC to MIEX(®) amenable DOC. As a result, BAC/MIEX(®) combination synergised DOC removal. In addition, BAC was also found to be highly effective in reducing MIEX(®) dose for a given DOC removal from SWWE.
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.
