Full Description

The magnetic ion exchange (MIEX) resin is a valuabletechnology to assist in controlling disinfection byproductsand reducing chemical requirements (e.g.,coagulants, oxidants, and disinfectants) in downstreamtreatment processes. The MIEX process has been in usesince 2002, and many utilities and consulting engineershave tested the resin on a site-specific basis. The workdescribed in this paper compared results from batch-, pilot-, andfull-scale tests to create a composite picture of MIEXprocess performance.The authors found that effective removal of dissolvedorganic carbon (DOC) can be achieved at resindoses of 0.5-1.0 mL of resin per liter of water treatedor bed volume rates on the order of 1,000 L of watertreated per liter of resin regenerated. In addition, theircomparison of DOC removal results in batch and continuous-flow studies using the same water showed thatbatch test results can be used effectively to scaleup tofull-scale performance. Includes 19 references, tables, figures.
