An anaerobic membrane bioreactor using a hollow fiber membrane and biogas agitation

Year: 2020

Type: article

Abstract: Many biomass disposal demonstration projects are based on anaerobic digestion. However, the excessively slow anaerobic microorganism growth rate is a drawback because a decreased anaerobic microorganism population limits methane fermentation's efficiency. To ensure operation at higher loads, this study used an anaerobic membrane bioreactor (AnMBR) for maintaining anaerobic microorganisms' growth, and this article introduces a series of improvements to address the reactor's shortcomings. Finally, we chose to mix-the internal biogas and conducted the experiment using a hollow fiber AnMBR.•Introducing the design of a highly efficient and compact anaerobic membrane bioreactor (AnMBR).•Introducing the initial OLR and the changes of HRT, SRT, TS, and flux of the permeate in the AnMBR after gradually increasing the load.•Monitoring decomposition characteristics in the gas meter connection.
