Microbiology of Wastewater Treatment
This webinar introduces the audience to the microorganisms that thrive in activated sludge. Changes in the environment of the aeration tank will cause different bacteria to grow. In particular, the filamentous bacteria will especially dominate when specific activated sludge environment supports their growth. Therefore, if you don’t like what has grown, change the aeration tank environment and something different will grow – hopefully settling better in the clarifier.

- Jon van Dommelen has worked for Ohio EPA for 25 years. He spent the first 6 years reviewing detailed plans and issuing permits to install for new wastewater treatment, plants and collections systems in the Division of Environmental and Financial Assistance. He eventually transferred to the Division of Surface Water, joining the Compliance Assistance Unit. Four years ago, he returned to DEFA along with the CAU. 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.
