Despite municipal chlorination and secondary disinfection, opportunistic waterborne pathogens (e.g., Legionella spp.) persist in public and private water distribution systems. As a potential source of healthcare-acquired infections, this warrants development of novel pathogen removal and inactivation systems. In this study, electrically heatable carbon nanotube (CNT) point-of-use (POU) filters have been designed to remove and inactivate Legionella pneumophila in water. The CNT/polymer composite membranes effectively removed Legionella (> 99.99%) (i.e., below detection limit) and were able to inactive them on the membrane surface at 100% efficiency within 60 s using ohmic heating at 20 V. The novel POU filters could be used as a final barrier to provide efficient rejection of pathogens and thereby simultaneously eliminate microorganisms in public and private water supplies.

可电加热的碳纳米管使用点过滤器，用于有效分离和原地灭活嗜肺军团菌。

尽管市政进行了加氯和二次消毒，但机会性的水传播病原体（例如军团菌）仍存在于公共和私人的供水系统中。作为卫生保健获得性感染的潜在来源，这有必要开发新型的病原体去除和灭活系统。在这项研究中，已设计了可电加热的碳纳米管（CNT）使用点（POU）过滤器，用于去除水中的嗜肺军团菌并使之灭活。CNT /聚合物复合膜有效去除军团菌（> 99.99％）（即低于检测极限），并且能够使用20 V的欧姆加热在60 s内以100％的效率使它们在膜表面失活。
