自主设计了弯曲板式膜系统，优化了膜壳和膜元件，使得系统能够获得稳定的通量和高质量滤液。该系统对赤霉素过滤的通量可以稳定在65 L•m-2•h-1；对于头孢C的过滤，通量可以稳定在15 L•m-2•h-1，系统对二者的蛋白截留率超过85％。

The bent flat membrane（BFM）system was designed by optimizing membrane tube and membrane element for achieving steady flux and high quality filtrate. The flux could be stable at 65 L•m-2•h-1, when this system was used for filtrating gibberellins, and 15 L•m-2•h-1 for filtrating cephalosporin C. Meanwhile, the protein retentate rate of gibberellins and cephalosporin C was higher than 85%.
