The optimal operational parameters of a second generation magnetically induced membrane vibration (MMV) system were determined using the response surface methodology (RSM) combined with single-factor experiments. The membrane surfaces were characterized by scanning electron microscopy (SEM) and algae cell states by inverted microscopy. The effect of an intermittent vibration strategy on filtration performance and energy consumption was studied. The results showed that the responses could be fitted by RSM models. High membrane flux, low energy consumption, efficient fouling control and no damage to the microalgae could thus be realized. The filtration strategy tests suggested that an intermittent cycle time of 4 min with 50% vibration rate could be the best vibration strategy for harvesting the microalgae under investigation.
采用响应面法（RSM）结合单因素实验，确定了第二代磁致膜振动（MMV）系统的最佳运行参数。通过扫描电子显微镜（SEM）对膜表面进行了表征，通过倒置显微镜对藻类细胞状态进行了表征。研究了间歇振动策略对过滤性能和能耗的影响。结果表明，响应可以用 RSM 模型来拟合。因此，可以实现高通量、低能耗、有效控制污染和对微藻无损伤。过滤策略测试表明，间歇循环时间为 4 分钟，振动率为 50%，可能是研究中收获微藻的最佳振动策略。
