To assess the potential of pepper mild mottle virus (PMMoV) as a viral process indicator, its reduction through coagulation–sedimentation (CS) and rapid sand filtration (RSF) were compared with those of Escherichia coli, previously used viral indicators, and norovirus genotype II (NoV GII; enteric virus reference pathogen) in a bench-scale experiment. PMMoV log₁₀ reductions in CS (1.96 ± 0.30) and RSF (0.26 ± 0.38) were similar to those of NoV GII (1.86 ± 0.61 and 0.28 ± 0.46). PMMoV, the most abundant viruses in the raw water, was also determined during CS, RSF, and advanced treatment processes at two full-scale drinking water treatment plants under strict turbidity management over a 13-month period. PMMoV was concentrated from large-volume water samples (10–614 L) and quantified by Taqman-based quantitative polymerase chain reaction. The PMMoV log₁₀ reduction in CS (2.38 ± 0.74, n = 13 and 2.63 ± 0.76, n = 10 each for Plant A and B) and in ozonation (1.91 ± 1.18, n = 5, Plant A) greatly contributed to the overall log₁₀ reduction. Our results suggest that PMMoV can act as a useful treatment process indicator of enteric viruses and can be used to monitor the log₁₀ reduction of individual treatment processes at drinking water treatment plants due to its high and consistent copy numbers in source water.

为了评估胡椒轻斑驳病毒（PMMoV）作为病毒过程指标的潜力，将其通过凝结沉淀（CS）和快速砂滤（RSF）的减少与大肠杆菌，以前使用的病毒指标和诺如病毒基因型进行了比较。 II（NoV GII；肠病毒参考病原体）进行基准试验。PMMoV日志₁₀CS（1.96±0.30）和RSF（0.26±0.38）的降低与NoV GII的降低（1.86±0.61和0.28±0.46）相似。PMMoV是原水中最丰富的病毒，也是在CS，RSF和高级处理过程中，在严格的浊度管理下经过13个月的时间，在两家大型饮用水处理厂中确定的。PMMoV从大量水样（10–614 L）中浓缩，并通过基于Taqman的定量聚合酶链反应进行定量。CS和PMMoV log _10的减少量（植物A和B分别为2.38±0.74，n = 13和2.63±0.76，n = 10）和臭氧化作用（1.91±1.18，n = 5，植物A）的降低很大日志₁₀减少。我们的结果表明，PMMoV可以作为肠道病毒治疗过程的有用指示剂，并且由于其在源水中的拷贝数较高且一致，因此可用于监测饮用水处理厂中各个处理过程的log ₁₀减少。
