Another great event with Marquette University in the books!

Their Anaerobic Treatment Short Course covered real-world challenges in anaerobic systems, and we were proud to be part of the lineup, sharing insights on reactor stability, monitoring strategies, and real-world troubleshooting from the field.

Beyond the sessions, it was a great chance to reconnect with familiar faces and meet new ones across the industry. Thanks to Marquette University for putting together such a strong program, we're already looking forward to next year.
