Removals of MS2 bacteriophage virus using different membrane materials under different operating pressures were investigated. The results obtained in this study suggested that a better log removal in terms of MS2 bacteriophage virus could be achieved using Polyamide RO membrane under the optimum operating pressure of 100 psi. It is further noted that variable MS2 influent concentration levels resulted in corresponding variable log removals of the bacteriophages by the Polyamide RO membrane. The presence of MS2 bacteriophage virus in the effluent could possibly be due to leakage of bacteriophages through the membranes structure. Investigations using SEM and AFM showed that there were gaps or pores present in the membrane structure which were sufficiently large for the MS2 viruses to pass through.
研究了在不同操作压力下使用不同膜材料去除MS2噬菌体病毒的情况。本研究获得的结果表明，在100 psi的最佳操作压力下使用聚酰胺反渗透膜可以实现对MS2噬菌体病毒更好的对数去除率。进一步指出，MS2进水浓度水平的变化导致聚酰胺反渗透膜对噬菌体的对数去除率相应变化。出水口中存在MS2噬菌体病毒可能是由于噬菌体通过膜结构泄漏所致。使用扫描电子显微镜（SEM）和原子力显微镜（AFM）进行的研究表明，膜结构中存在足够大的间隙或孔隙，足以让MS2病毒通过。
