Abstract

Viruses in wastewater effluent pose significant public health risks, and achieving high log reduction values is critical for wastewater reuse applications. The influence of ionic surfactants sodium dodecyl sulfate (SDS) and benzyldimethyldodecylammonium chloride (BAC) in wastewater on virus removal and infectivity after microfiltration (200 nm cutoff) was investigated. Microfiltration log rejection values (LRVs) for infective human adenovirus (ADV, nonenveloped, 90-nm diameter) and mouse hepatitis virus (MHV, enveloped, 80- to 120-nm diameter) increased when surfactants were present in wastewater from 4.3 to 6.8-7.1 and from 4.8 to 4.9-5.1 LRV for ADV and MHV, respectively. Lower LRVs were found when using quantitative polymerase chain reaction (qPCR) than by TCID₅₀/mL infectives for both viruses, specifically from 1.4 to 3.4 for ADV and MHV, respectively. SEM-EDS confirmed aggregated virus and surfactant sorption on the membrane. This work advanced understanding of microfiltration virus log reduction influenced by surfactants and is applicable to wastewater reuse.

离子表面活性剂对包膜和非包膜病毒微滤的影响。

废水中的病毒构成重大的公共卫生风险，实现高对数降低值对于废水回用应用至关重要。研究了离子表面活性剂十二烷基硫酸钠（SDS）和苄基二甲基十二烷基氯化铵（BAC）对微滤（200 nm截止）废水中病毒去除率和感染性的影响。当废水中存在表面活性剂时，传染性人腺病毒（ADV，无包膜，直径90 nm）和小鼠肝炎病毒（MHV，包膜，直径80 ~ 120 nm）的微滤对数排斥值（LRV）分别从4.3增加到6.8 ~ 7.1和4.8增加到4.9 ~ 5.1 LRV。与TCID50/mL感染相比，采用定量聚合酶链反应（qPCR）检测两种病毒的lrv均较低，ADV和MHV分别为1.4 ~ 3.4。扫描电镜能谱仪证实病毒聚集，表面活性剂在膜上吸附。本研究提高了对表面活性剂影响下微滤病毒对数降低的认识，并适用于废水回用。

期刊介绍： Published since 1928, Water Environment Research (WER) is an international multidisciplinary water resource management journal for the dissemination of fundamental and applied research in all scientific and technical areas related to water quality and resource recovery. WER''s goal is to foster communication and interdisciplinary research between water sciences and related fields such as environmental toxicology, agriculture, public and occupational health, microbiology, and ecology. In addition to original research articles, short communications, case studies, reviews, and perspectives are encouraged.
