Free Webinars: Optimizing Performance of Wastewater Lagoon Systems

The U.S. Environmental Protection Agency (EPA) is presenting a series of technical assistance webinars to highlight best practices for optimizing performance at small wastewater treatment lagoons.

These webinars will cover methods, techniques, and strategies that operators can use to get better BOD₅ (5-day biochemical oxygen demand) reduction, TSS (total suspended solids) removal, odor control, sludge reduction, and nutrient removal, and to ultimately extend the dependable service years of the lagoon system.

Attendees will learn how to fine-tune their systems using relatively simple process control tools to optimize performance and return their system to compliance. While all plant operators may benefit from this information, these webinars are geared toward operators of smaller systems with a flow of less than 1 million gallons per day. Attendees will be able to ask questions via a chat box.

To register to attend the webinars, please visit the EPA’s GoTo Webinar registration pages for Optimizing Performance of Facultative Wastewater Lagoon Systems (Part 1 of 2) and Optimizing Performance of Aerated Wastewater Lagoon Systems (Part 2 of 2) .

These webinars will be fast-paced and will cover a lot of topics. To get the most benefit from them, attendees are encouraged to review these background materials prior to the webinars:
