Bill Marten is a presenter at Indiana Water Environment Association’s (WEA’s) Core Conference hosted by the IWEA Laboratory, Operations & Maintenance, and Residuals & Resource Recovery Committees.
Nitrification is an advanced nutrient removal process that has been around a long time in wastewater treatment, and is well understood and easily designed and operated to achieve desired levels of ammonia removal, right? Well…that’s the common belief, and a belief Bill held for many years until several recent experiences at operating plants showed him “You Really Don’t Know All You Think You Do!”
His presentation reviews the basics of common understandings of nitrification in activated sludge. He discusses several recent case histories where nitrification operations showed unexpected results, and how plant staff responded to overcome and/or optimize their nitrifying activated sludge performance.
A senior Donohue wastewater engineer with four decades of hands-on wastewater treatment engineering and operations experience, Bill is Donohue’s Practice Leader for Wastewater Biological Processes and Nutrient Removal. He holds graduate and undergraduate degrees in civil/environmental engineering from the University of Wisconsin–Madison.
