Unwoven cloth coated with 32 mg/g of a copolymer of N-benzyl-4-vinyl-pyridinium chloride and styrene was found to be effective in removing micro-organisms from water. In experiments demonstrating removal of Escherichia coli by filtration through ten sheets of the unwoven cloth, the rate of removal was 99.99% at a filtration rate of 2.6 cm/h, and remained at 99% even at a high filtration rate of 300 cm/h and a low influent concentration of the bacterial cells such as 10(3) cells/ml. The rate of removal tended to increase with a decrease in the influent bacterial concentration. Seven other bacteria and two yeasts were effectively removed by filtration through the unwoven cloth. Filtration through the unwoven cloth was also effective in removing spores of fungi from water but was not very effective in removing bacteriophage T4 from aqueous solution.
发现涂覆有32毫克/克N-苄基-4-乙烯基吡啶氯化物与苯乙烯共聚物的无纺布可有效去除水中的微生物。在通过十片无纺布过滤去除大肠杆菌的实验中，过滤速度为2.6厘米/小时时，去除率为99.99%，即使在300厘米/小时的高过滤速度和10(3)个细胞/毫升的低细菌细胞进水浓度下，去除率仍保持在99%。去除率往往随着进水细菌浓度的降低而增加。通过无纺布过滤可有效去除其他七种细菌和两种酵母。通过无纺布过滤也可有效去除水中的真菌孢子，但对从水溶液中去除噬菌体T4不是很有效。
