The objective of this paper was to evaluate and provide recommendations for improvement, if required, to a membrane bioreactor wastewater treatment system after 10 years of operation. When this treatment plant was designed, it was to the current industry standards for membrane design. Of particular interest was the condition of the screening system and the membrane system. This paper highlights the findings and lessons learned from the evaluation.
