Case Study of Energy Efficient, Sustainable Improvements and Technologies Implemented at Wastewater Treatment Plants

The goal to operate economically sustainable wastewater treatment facilities has pushed entities throughout New York State to identify and implement energy efficient facility and technology improvements. This paper will paper will provide a case study of results from projects and programs at nine wastewater treatment systems. The paper will provide energy savings, construction costs and return on investment information on technologies including aeration diffuser upgrades, blower upgrades, dissolved oxygen and pumping control systems, digester mixing systems, anaerobic digester gas collection, belt press upgrades and replacement, lighting upgrades, HVAC upgrades and energy management systems.
