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.
This February, BOSS Magazine featured an article on the capacity increase project at Dublin Road Water Treatment facility that discussed the leadership, innovation, collaboration, sustainability and best operational procedures incorporated into the plant. Purolite was invited to provide a company showcase for the issue because we played a significant role in the upgrade and the control of nitrate in the treated water. The showcase page on the project will be available online through 2018.Purolite`s team worked...

Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. Activated carbon works through as an adsorption medium. When the carbon has been saturated with contaminants, it will need to be replaced with new...
Ion exchange (IX) systems can be an efficient solution for various demineralization, purification, and wastewater treatment needs. In fact, IX systems deliver several advantages over chemical treatment, as they generally require less space, less labor, no sludge disposal, and lower operational costs.
While such benefits are attractive, you might be left wondering “What are common problems with ion exchange and how do I fix them?” This article will offer insight into the key conditions and issues that...
