| Abstract: | Membrane fouling is a major obstacle that hinders faster commercialization of membrane bioreactor (MBR). A comprehensive study into the effect of NaClO on the biofouling of MBR will benefit us to develop more effective on-line chemical cleaning technologies, which will also improve the application to the actual engineering optimal design. The article summarized studies on the effect of the biofouling and bioflocculation during the in-situ cleaning with NaClO in MBR with respect to the distribution of extracellular substances, and the mechanism of NaClO-triggered activated sludge reconstruction as well as enhance bioflocculation methods were also discussed. Lastly, the future trends in the in-situ cleaning of MBR in the coming years were addressed. |
