Optimizing Nutrient Removal in Oxidation Ditches
Training Video
The speaker shares case studies regarding oxidation ditch wastewater treatment plants (WWTPs) that are operated differently than designed to achieve notable reductions in effluent nitrogen and phosphorus, and explain how listeners might modify day-to-day operations at their oxidation ditch WWTPs to realize similar improvements. Among the case studies will be oxidation ditch facilities in Chinook, Montana; Great Bend, Kansas; and Cookeville, Tennessee. The case studies are preceded by a brief overview of biological nitrogen removal and biological phosphorus removal science and technology.

He was born in Kansas and educated at state schools before sneaking into MIT for a post-Graduate education in Environmental Toxicology. Grant’s MS is in Bio-Environmental Engineering (Oklahoma State University)and his BS is in Biology (Kansas State University).
He has spoken to wastewater operators across the county in countless classroom and webinar presentations. Grant is a contrarian who gets pleasure from empowering wastewater operators to make treatment plants work better than those who design and regulate them believe they can.
In this regard, he has visited and worked with the staffs of over 150 North American municipal wastewater treatment plants to realize significant improvements in nitrogen and phosphorus removal.
