Lastly, challenges and future views related to the co-digestion functions by AnMBR had been totally discussed. Although it provides varied benefits to achieve energy-efficient WWTPs, membrane fouling stays one of many major challenges for co-digestion purposes by AnMBRs. Zhen et al. (2023) built-in electrochemical regulation into the AnMBR for co-digestion to attenuate membrane fouling. It was indicated that electrochemical regulation accelerated the mineralization of high molecular weight organics and lowered the propensity of the membrane for fouling. Though utilized voltage causes additional operational value, increased methane restoration could compensate for it and increase the applicability of such a course of (Wang et al. 2022). Though the elevated voltage above sure limits cause harm and stop the proliferation of useful microorganism, the optimum applied voltage provided appreciable enhancement relative abundance in all bacteria. Changes within the relative abundance of Proteobacteria, Bacteroidetes, Chloroflexi, and Spirochaetes had been exceptional with the utilized electrochemical stimulation. Serna-Garcia et al. (2020b) investigated the impact of OLR on microbial communities in thermophilic AnMBR where PS and microalgae co-digested. Since the membrane module can retain the microorganisms, the AnMBR system allowed a diversified microbial community in comparison with the CAD system. Even although the range of the microorganisms was comparable, it was seen that the relative abundance of the microorganisms was differentiated in different OLRs.
