A lab-scale Self-Forming Dynamic Membrane BioReactor (SFD MBR) equipped with a nylon mesh was operated for the treatment of real municipal wastewater under a volumetric loading rate of 0.9–1.1 gCOD L⁻¹ d⁻¹ and a flux of 61–68 L m⁻² h⁻¹. During an experimental period of more than 600 d, three runs were performed with different solids retention times (SRT of 15, 30, and 50 d). At the steady state, the system had always good biological and filtration performances, but the mesh clogging tendency and the solid removal observed varied with the SRT. Lower filtration performance, both in terms of permeate quality and productivity, was observed under unstable conditions for the biological processes, such as start-up and variations of the food-to-microorganism ratio. Higher SRT resulted in more stable biological process at the steady state, which positively affected the filtration performance even in front of organic load variations.

实验室规模的配备尼龙网的自成型动态膜生物反应器（SFD MBR）用于处理实际市政废水，其容积率为0.9–1.1 gCOD L ^-1 d ^-1和通量为61– 68毫米m ^-2小时^-1。在超过600 d的实验期间，以不同的固体保留时间（SRT为15、30和50 d）进行了3次运行。在稳定状态下，该系统始终具有良好的生物学和过滤性能，但观察到的网眼堵塞趋势和固体去除随SRT的不同而不同。在生物过程的不稳定条件下（例如启动和食品与微生物比例的变化），观察到了较低的过滤性能，无论是渗透质量还是生产率。较高的SRT可使稳态下的生物过程更稳定，即使在有机负荷变化之前，也对过滤性能产生积极影响。
