High Temperature Effects on Activated Sludge Treatment Performance and Sludge Quality in a Recycle Mill, 2000 Environmental Conference Proceedings

- P. Norris, R. Marshall, M. Richard -- Mill wastewater temperature has been increasing due to newer mill processes. This has resulted in biological upset and poor performance of mill activated sludge systems at treatment temperatures above 35 degrees C. McKinley Paper Co., a 100% recycle mill, operates a sequencing batch reactor activated sludge system for treatment of its wastewater. This mill has had frequent and severe biological upsets in wastewater treatment. One possible cause of these upsets is a hot mill wastewater above 35-40 degrees C. A bench scale study was conducted by the papermill personnel to evaluate the effect of high treatment temperature in the range 35-56 degrees C on activated sludge performance and sludge quality.
