河岸过滤(RBF)为供水商提供 控制癌症的替代治疗方案 消毒副产物(DBPs)和微生物 污染物。在RBF过程中,水渗入 穿过含水层沉积物,经历 物理、化学和生物的结合 可以显著改善原水水质的工艺 质量尽管径向基函数已经被广泛应用于 多年来,欧洲只是在最近才吸引了 美国公用事业公司的兴趣和支持。 这项研究监测了DBP前体的命运 以及在三个中西部地区进行RBF期间选择的微生物 美国饮用水网站。 结果显示 RBF成功地控制了DBP的形成 并为微生物污染提供了一道屏障 饮用水供应。有了RBF,所有三个站点都有经验 有机碳总量显著减少, 溶解有机碳和DBP前体。 美国环境保护署目前正在 考虑分配贾第虫和隐孢子虫 在开发过程中,治疗归功于RBF 长期2强化地表水处理 规则这项研究为公用事业公司和立法者提供了数据 确认RBF是一种有效的治疗方案,以及 支持信用证处理的申请 过程包括60个参考文献、表格和图表。
Riverbank filtration (RBF) offers water suppliers an alternative treatment option for the control of disinfection byproducts (DBPs) and microbial contaminants. In the process of RBF, water infiltrates and travels through aquifer sediments, undergoing a combination of physical, chemical, and biological processes that can significantly improve raw water quality. Although RBF has been extensively used in Europe for many years, it has only recently attracted interest and support among US utilities. This study monitored the fate of DBP precursors and selected microorganisms during RBF at three Midwestern US drinking water sites. Results demonstrated that RBF was successful at controlling DBP formation and provided a barrier to microbial contamination of drinking water supplies. With RBF, all three sites experienced significant reductions in total organic carbon, dissolved organic carbon, and DBP precursors. The US Environmental Protection Agency is currently considering assigning Giardia and Cryptosporidium treatment credit to RBF in the development of the Long-Term 2 Enhanced Surface Water Treatment Rule. This research gives utilities and legislators data to confirm RBF as an effective treatment option and support the application of treatment credits to the process. Includes 60 references, tables, figures.
