The magnetic ion exchange (MIEX®) resin is a valuable technology to assist in controlling disinfection byproducts and reducing chemical requirements (e.g., coagulants, oxidants, and disinfectants) in downstream treatment processes. The MIEX process has been in use since 2002, and many utilities and consulting engineers have tested the resin on a site-specific basis. The work described here compared results from batch-, pilot-, and full-scale tests to create a composite picture of MIEX process performance. The authors found that effective removal of dissolved organic carbon (DOC) can be achieved at resin doses of 0.5-1.0 mL of resin per litre of water treated or bed volume rates on the order of 1,000 L of water treated per litre of resin regenerated. In addition, their comparison of DOC removal results in batch and continuous-flow studies using the same water showed that batch test results can be used effectively to scaleup to full-scale performance. - MPM.
