Implementing Food Waste Co‐digestion at Wastewater Treatment Plants: Planning and Operations - Part 2 - Live Webinar

Recorded On: 05/04/2021

  • Registration Closed

Member fee: $38.00
Non-Member fee: $53.00

1.8 contact hours towards CWEA's  Electrical / Instrumentation Technician, Environmental Compliance Inspector, and Mechanical Technologist certifications

In this webinar, you’ll learn:

• Review of factors influencing feasibility of co digestion with organic co substrates and long term planning considerations to balance sustainability and performance goals at resource recovery facilities.
• Learn about treatment technologies that may be implemented to improve handling of high strength waste (HSW).
• Recognize challenges associated with feedstock and how to address these challenges.
• Understand how microbial communities involved in the co digestion of wastewater residuals respond to different co substrates and operational conditions.
• Become familiar with operational factors that influence successful integration and optimization of co digestion practices.
