Energy Conservation in Wastewater Treatment Plants
Thursday, April 5, 2018 - 8:00am to 5:00pm
23 slots available
Training Overview:

Water and wastewater treatment represent approximately 4% of the total electricity used in the US. Because of stringent regulations, complex biological treatment processes, and sophisticated process equipment, operators have been slow in adopting ECMs.
This course will identify operator concerns, explain treatment process constraints, and identify ECM opportunities that will actually enhance process performance AND energy efficiency.

Event Benefits:

Learning Objectives:
As a result of this training, participants will be able to:
1. Discuss operator concerns and opportunities without getting lost in industry specific jargon
2. Understand process and equipment basics
3. Determine the cost effectiveness of various ECM opportunities
4. Recommend opportunities for further analysis by engineering consultants
5. Review applications for incentive programs from wastewater treatment facilities

Who Should Attend:

Plant Managers
Municipal Wastewater personnel
NGRID personnel
EVERSOURCE personnel
Wastewater Techs
