Energy efficiency in small to medium wastewater treatment facilities
- COURSE OUTLINE
- SPEAKER BIO(S)
As a result of this course, you will be able to:
- Explain a wastewater treatment facility’s electric energy bills.
- Discuss baselines and benchmarks for energy consumption.
- Describe the savings potential for the most common energy efficiency improvements.
- List projects for implementation based on priority.
Basic understanding of common wastewater treatment processes and equipment.
Who should attend?
Maintenance personnel, operators, regulators, contractors, energy efficiency specialists, plant managers, engineers and anyone with a basic understanding of common wastewater treatment processes and equipment, as well as an interest in learning more about energy management in wastewater treatment facilities.
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.
