Abstract

While high solid anaerobic digestion has the potential to produce more biogas with the same anaerobic reactor, its rheological behavior can lead to short-circuiting and dead zones, significantly limiting the anaerobic fermentation efficiency. This study numerically investigates the sludge movement in an industrial-scale continuously stirred tank reactor and explores the dynamic characteristics of the anaerobic digestion process under varied agitation conditions and sludge properties. A novel approach was developed, estimating the biogas production rate based on local fluid behavior. The numerical results revealed that over-agitation can restrict anaerobic digestion efficiency, with the critical value increasing as total solid content rises. For 16.4 % total solids (TS) active sludge, the highest biogas production rate was achieved at 30 RPM in this study. In contrast, the biogas production rate of 18.7 % TS active sludge continuously increased with agitation rate, with over-agitation speeds considered to be over 80 RPM.
