Full-scale anaerobic digesters (AD`s) in three different wastewater treatment plants (WWTPs) were compared to study the effects of feeding and mixing on biogas production, total solids (TS) and temperature variation inside the digesters. In the three studies, mixing frequency was significantly reduced in both egg-shaped and cylindrical digesters. Total solids and temperature monitoring along the depth of the digesters illustrated that reducing mixing frequency by up to 75% did not significantly impact digester performance. This study demonstrates that significant energy savings can be accomplished by optimizing digester mixing without compromising performance. Reduced mixing has resulted in significant energy savings to the utilities that participated in the study.
