Performance of AnMBRs treating low strength wastewater with different carbon sources at decreasing HRTs and its linkage to Methanosaeta with high specific affinity

Abstract

Minimum hydraulic retention time needs to be considered to avoid methanogenesis inhibition for complex substrates in anaerobic membrane bioreactor for low-strength wastewater treatment.

A critical review on advanced anaerobic membrane bioreactors (AnMBRs) for wastewater treatment: advanced membrane materials and energy demand

“…87 Furthermore, several techniques including preconcentration of wastewater, culturing psychrophilic-adapted methanogens and enhancing the OLR are suggested for operating AnMBRs under psychrophilic conditions. 85,88,89 In order to further understand the microbial behaviour, many scientists analysed the effect of HRT. They showed that an increased amount of hydrogenotrophic methanogens was witnessed with the decrease in HRT.…”
