纳滤（NF）膜系统通常在相对较低的压力范围内运行。 其中一个主要原因是NF膜对水污染物的截留 相对较高的压力受浓度极化的影响。然而，实验性的 这项研究的结果显示，即使MS2噬菌体最初被排斥 当跨膜压力升高时，浓度降低 极化效应下，随着极化强度的进一步增加，排斥反应有增加的趋势 超过一定压力/水流量值的压力。这一现象是通过实验观察到的 pH值为6-7.6和11-25ºC的ESNA1®（加利福尼亚州Oceanside Hydranautics）纳滤膜。包括9个参考文献、图。

Nanofiltration (NF) membrane systems are typically operated in relatively low-pressure range. One of the main reasons is that the rejection of water contaminants by NF membranes at relatively high pressure is affected by concentration polarization. However, experimental results from this study revealed that even though the rejection of MS2 phage initially decreased when trans-membrane pressure went up, as a result of the concentration polarization effect, an increasing trend of rejection was observed with further increases in pressure in excess of a certain pressure/water flux value. This phenomenon was observed with ESNA1® (Hydranautics, Oceanside, CA) NF membranes at pH 6-7.6 and 11-25ºC. Includes 9 references, figures.
