Test your knowledge of wastewater energy efficiency

Have you questioned your wastewater treatment facility’s energy bill lately? Join us to find ways to control this business expense and improve treatment while not sacrificing water quality. A brief overview of the nature of electric energy use and cost at a typical wastewater treatment facility will set the stage. Next, we’ll make the case for why the comprehension and analysis of electric bills is so important, along with the need to establish baselines and benchmarks.

The most common and cost effective energy efficiency improvements in wastewater treatment facilities will be examined, as well as the relationship between process and energy performance. We’ll explore diffused and mechanical aeration, dissolved oxygen control and aeration automation, blower technologies, pumping and pumping systems, combined heat and power, co-digestion, HVAC and lighting energy efficiency opportunities. Techniques for calculating savings and cost effectiveness for each energy efficiency improvement will be explained and demonstrated.

An optional tour of the Eau Claire Wastewater Treatment Plant located at 1000 Ferry St, Eau Claire, WI 54703 will follow this course.
