Ammonia and nitrite in aquaculture recirculating seawater need to be strictly controlled to avoid deleterious effects on aquatic organisms. However, traditional biological approach can hardly meet the standard due to the short hydraulic retention time (HRT) and nitrite accumulation. A Membrane Electro-Bioreactor (MEBR) was developed for ammonia removal enhancement and in-situ electrochemical membrane fouling mitigation. The fouling mechanism was first found to proceed via the standard filtration model. The flux decrease was mainly caused by an internal pore clogging phenomenon. Membrane fouling resistance was enhanced by increasing anode potential from 0 to 1.4 V vs. SCE (Saturated Calomel Electrode). The ammonia removal rate in the MEBR was above 95% (HRT: 2 h, after day-13) and membrane fouling was mitigated that operation duration was extended by 71.4%. Higher total proportion of Proteobacteria, Bacteroidetes, Planctomycetes and Actinobacteria was obtained in the MEBR, suggesting higher nitrification and nitrogen removal potentials.

水产养殖循环海水中的氨和亚硝酸盐需要严格控制，以避免对水生生物造成有害影响。但是，传统的生物方法由于水力停留时间（HRT）和亚硝酸盐积累时间短而难以达到标准。膜电生物反应器（MEBR）被开发用于增强氨去除和原位电化学膜结垢缓解。首先发现结垢机理是通过标准过滤模型进行的。通量下降主要是由内部孔堵塞现象引起的。相对于SCE（饱和甘汞电极），将阳极电势从0 V增加到1.4 V，可以增强膜的抗污垢性。MEBR中的氨去除率高于95％（HRT：2 h，在第13天后），膜结垢得到缓解，手术时间延长了71.4％。占总比例较高在MEBR中获得了变形杆菌，拟杆菌，扁平菌和放线菌，这表明更高的硝化和脱氮潜能。
