Abstract The adoption of process intensification to anaerobic digestion can present significant complications for digester mixing and process performance. This work investigated how increasing the solids concentration of the digester sludge influenced the process at various mixing energy inputs. Based on the results, adequate mixing is defined qualitatively as the input of sufficient energy to mobilize the reactor contents without producing significant regions of inhibitory shear force. However, the quantitative definition is dependent on the solids concentration of the sludge. But, the existing design criterion of specific mixing power input based on fluid volume (W/m(3)) does not represent it well. Therefore, a new design criterion of specific mixing power input based on total solids in the sludge (W/kgTS) is proposed to achieve maximum biogas production using optimum power input. The relationship has its limitations, but it represents a significant step forward in the design and operation of improved digester mixing systems.
