摘要

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. 磁性离子交换树脂（MIEX®）是一种有价值的材料协助控制消毒副产品的技术以及减少化学品需求（例如。，下游的凝固剂、氧化剂和消毒剂）治疗过程。MIEX工艺已经投入使用自2002年以来，许多公用事业和咨询工程师我们已经在特定地点对树脂进行了测试。工作本文介绍了批量、中试和试验结果的比较创建MIEX合成图片的全面测试过程性能。作者发现，有效去除溶解的有机碳（DOC）可以在树脂上实现每升处理过的水添加0.5-1.0毫升树脂或床层容积率约为1000升水每升再生树脂处理一次。此外，他们的批量和连续单据删除结果的比较-用同样的水进行的流动研究表明批量测试结果可以有效地用于扩展到全面的表现。包括19个参考文献、表格和图表。展开▼
