In view of the differences that have been found between the most-probable-number and membrane filtration methods for the recovery of coliforms from chlorinated samples, the survival of total and fecal coliforms in UV-irradiated effluent samples, as tested by the most-probable-number and standard single-step membrane filtration methods, was compared. There were no significant differences in the survival of total and fecal coliforms, as tested by the two methods. In a separate set of experiments comparing total and fecal coliform survival, as tested by the most-probable-number method, only a very small but statistically significant difference of 0.1 log survival units was found. For UV-disinfected wastewater effluents, standard one-step membrane filtration procedures are comparable to standard most-probable-number procedures.
鉴于已发现从氯化样品中回收大肠菌群的最大可能数法和膜过滤法之间存在差异，比较了通过最大可能数法和标准单步膜过滤法测试的紫外线辐照废水样品中总大肠菌群和粪大肠菌群的存活情况。两种方法测试的总大肠菌群和粪大肠菌群的存活情况没有显著差异。在另一组通过最大可能数法比较总大肠菌群和粪大肠菌群存活情况的实验中，仅发现了0.1个对数存活单位的非常小但具有统计学意义的差异。对于紫外线消毒的废水，标准单步膜过滤程序与标准最大可能数程序相当。
