本研究项目的目的是研究微生物污染物（主要是病毒）通过膜进入产品水中的机理。选择两种反渗透膜和两种纳滤膜作为代表性膜，在平叶系统中进行评估。除了病毒和溶质测试外，还尝试开发一种替代指标，以评估膜系统中的病毒排斥能力。所研究的替代指示剂为荧光染色聚苯乙烯微球。包括4个参考文献、图表。

The objective of this research project was to investigate the mechanism responsible for the transport of microbial contaminants, focusing on viruses, across the membrane and into the product water. Two reverse osmosis membranes and two nanofiltration membranes were chosen as representative membranes to be evaluated in a flat-leaf system. In addition to virus and solute testing, an attempt was made to develop a surrogate indicator to assess the capability for virus rejection in membrane systems. The surrogate indicator investigated was fluorescent dyed polystyrene microspheres. Includes 4 references, figures.
