This study was conducted to evaluate the removal of adenovirus, feline calicivirus (FCV), and bacteriophages MS-2, fr, PRD-1, and Phi X-174 during conventional drinking water treatment using ferric chloride as a coagulant. Adenovirus and FCV were removed to a greater extent than PRD-1 and Phi X-174, indicating that these bacteriophages may be appropriate surrogates for both adenovirus and FCV. Of the four bacteriophages studied in the pilot plant, MS-2 was removed to the greatest extent (5.1 log), followed by fr (4.9 log), PRD-1 (3.5 log), and Phi X-174 (1.3 log). The virus removal trend in the pilot-scale testing was similar to the bench-scale testing; however, the bench-scale testing seemed to provide a conservative estimate of the pilot plant performance. In the pilot-scale testing, MS-2 and fr were removed with the greatest efficiency during filtration, whereas PRD-1 and Phi X-174 showed the greatest removal during sedimentation.
本研究旨在评估使用氯化铁作为混凝剂的常规饮用水处理过程中腺病毒、猫杯状病毒（FCV）以及噬菌体MS-2、fr、PRD-1和Phi X-174的去除情况。腺病毒和FCV的去除程度高于PRD-1和Phi X-174，这表明这些噬菌体可能是腺病毒和FCV的合适替代物。在中试工厂研究的四种噬菌体中，MS-2的去除程度最大（5.1个对数级），其次是fr（4.9个对数级）、PRD-1（3.5个对数级）和Phi X-174（1.3个对数级）。中试规模测试中的病毒去除趋势与实验室规模测试相似；然而，实验室规模测试似乎对中试工厂性能提供了保守估计。在中试规模测试中，MS-2和fr在过滤过程中去除效率最高，而PRD-1和Phi X-174在沉淀过程中去除率最高。
