研究了试点水处理厂对天然存在和人为高水平的噬菌体 [T4] 和肠道病毒 [脊髓灰质炎病毒] 的影响。研究的各个阶段包括絮凝和沉淀、快速砂滤、活化 C 柱和最终氯化阶段。絮凝和沉淀装置始终有效，平均去除量为 99.7 .+-。 0.3%。快速砂滤器和活化 C 柱的效率取决于反冲洗的频率。这两个装置在最近反冲洗时效果较差，在这种情况下，与絮凝和沉淀装置相比，它们的去除百分比可以忽略不计。最终的氯化装置非常有效，如果残留游离 Cl 浓度保持在 0.4 mgl-1，则在此阶段后无法分离出病毒。对整个工厂的数据检查表明，它能够清除超过 99.9995% 的任何流入病毒。
The effect of a pilot water treatment plant upon naturally occurring and artificially high levels of bacteriophages [T4] and enteroviruses [poliovirus] was investigated. The individual stages studied were flocculation and sedimentation, rapid sand filtration, an activated C column and a final chlorination stage. The flocculation and sedimentation unit was consistently effective with an average removal of 99.7 .+-. 0.3%. The efficiency of the rapid sand filter and the activated C column was dependent upon the frequency of back-washing. Both units were less effective when recently back-washed and in such cases their percentage removal was negligible when compared with the flocculation and sedimentation unit. The final chlorination unit was very effective and viruses could not be isolated after this stage if a residual free Cl concentration of 0.4 mgl-1 was maintained. Examination of the data for the plant as a whole revealed that it was capable of removing greater than 99.9995% of any influent viruses.
