Troubleshooting Noncompliance at the Smallest Wastewater Treatment Plants – Part 2 (Solids Separation and Disinfection)
Learn about Ohio's Package Plant Initiative in which the state proactively addressed common compliance problems at the smallest mechanical activated sludge wastewater treatment plants (package plants). Part 1 covers how these small plants can overcome nutrient (ammonia) conversion problems. Part 2 covers how these small plants can overcome solids separation and disinfection problems.

He has worked in the CAU for a total of 19 years troubleshooting noncompliance at wastewater treatment plants ranging from 1500 gallon per day package plants up to 15 million gallon per day municipal systems. In addition, Jon has trained operators of WWTPs in process control of activated sludge, microbiology, biological nutrient removal, among other topics related to wastewater treatment. He has also presented at WEFTEC (3 times), at many OTCO and OWEA workshops, as well as for other regional, state, and local organizations. He has published articles pertaining to topics of interest to operators in the Buckeye Bulletin, a publication of the Ohio Water Environment Association. Jon graduated from Ohio State University with a Bachelor of Science in Civil Engineering and is a register Professional Engineer in the State of Ohio. His wife tells people that no one should have as much fun at their job as Jon does.
