The study analyses the performance of a pilot plant using a rotating hollow fibre (HF) membrane bioreactor system. The experiments evaluated the effect of operational parameters such as rotational speed, aeration strategies, and maintenance cleaning (MC) procedures on the efficiency of the system, in particular transmembrane pressure (TMP) and filtrate quality. The results indicate that the rotating membrane module reduces TMP increase and can operate for 48 days with satisfactory performance, even without aeration. This has the potential to significantly improve efficiency, resulting in significant energy savings. In addition, two MC methods, clean in air and clean in place, were tested and found to be efficient for weekly MC. It was observed that operating without aeration during colder seasons may not be effective. Therefore, adaptive strategies are needed to address seasonal temperature variations.
该研究分析了使用旋转中空纤维（HF）膜生物反应器系统的中试工厂的性能。实验评估了操作参数（如转速、曝气策略和维护清洁（MC）程序）对系统效率的影响，特别是对跨膜压力（TMP）和滤液质量的影响。结果表明，旋转膜组件可减少 TMP 的增加，即使在不曝气的情况下，也可以运行 48 天，性能仍令人满意。这有可能显著提高效率，从而节省大量能源。此外，还测试了两种 MC 方法，空气清洁和原位清洁，发现它们每周进行 MC 都非常有效。研究发现，在较冷的季节不曝气可能效果不佳。因此，需要采取适应策略来应对季节性温度变化。
