This study evaluated removal of live emerging waterborne pathogens by pilot‐scale conventional treatment with alum coagulation, flocculation, sedimentation, and filtration. The microbes tested were Cryptosporidium parvum oocysts, Encephalitozoon intestinalis spores, enteropathogenic Escherichia coli O157:H7, Aeromonas hydrophila, and bacteriophage MS2. The study showed the effects of filter run time, alternative loading rates, alternative filter media, and pH on pathogen removal. Results indicated that turbidity breakthrough was accompanied by breakthrough of all pathogens tested in this study. Results also suggest that the breakthrough of A. hydrophila and E. coli O157:H7 occurred more rapidly than that of turbidity. In general, filtration rate or alternative filter media configurations had no apparent effect on pathogen removal.

过滤条件对去除新出现的水传播病原体的影响

本研究评估了通过明矾混凝、絮凝、沉淀和过滤等中试规模的常规处理去除活的新兴水生病原体的情况。测试的微生物是小隐孢子虫卵囊,肠脑炎原虫孢子，肠道病原性大肠杆菌O157：H7，嗜水气单胞菌，和噬菌体MS2。该研究显示了过滤器运行时间、替代加载率、替代过滤介质和 pH 值对病原体去除的影响。结果表明，浊度突破伴随着本研究中测试的所有病原体的突破。结果还表明，突破嗜水气单胞菌和大肠杆菌O157:H7 比浊度发生得更快。一般来说，过滤速率或替代过滤介质配置对病原体去除没有明显影响。
