Dr. Stover served as the Project Director and Principal Author for the development of the Environmental Protection Agency’s Design Manual For Municipal Wastewater Disinfection (EPA/625/1-86/021).

Biological Wastewater Treatment Experience

Dr. Stover has over 39 years’ experience with biological nutrient removal and aerobic/anaerobic treatment technologies including research and development, process development, treatability and pilot studies, concept and process engineering designs, and operations of full-scale treatment facilities. This experience includes suspended growth, fixed-film, and modified hybrid types of systems.

Dr. Stover’s Ph.D. research and dissertation were on biological nitrification with both suspended growth and fixed-film treatment technologies. His interest in nutrient removal and control continued into the consulting field where he has been involved in numerous projects (both industrial and municipal) for both nitrogen and phosphorus removal and control. Projects have included biological nitrification, denitrification, and luxury phosphorus uptake and removal. While a professor at Oklahoma State University, Dr. Stover conducted an extensive amount of research and development with biological nutrient removal processes for both nitrogen and phosphorus removal. He has also performed an extensive amount of work with physical/chemical nitrogen and phosphorus removal processes including air and steam stripping and nitrogen and phosphorus precipitation. Projects have included full-scale applications for both industrial and municipal wastewaters.

Specific projects for nutrient removal in industrial wastewater have included soy bean processing, various types of food processing wastewaters, fertilizer, chemical, petrochemical, and refinery wastewaters. These nutrient removal projects have included treatability and pilot-scale studies, concept and process engineering, detail design and construction engineering and operations services. A list of relevant technical publications on nitrogen and phosphorus control follows.

Dr. Stover’s experience with anaerobic treatment has included many types of industrial wastewaters, as well as anaerobic sludge digestion, with various anaerobic treatment technologies. Examples of industrial wastewater projects have included palm oil wastes, fuel alcohol production, brewery, confectionary, dairy, rice processing, soy bean processing, corn processing, fish processing, potato processing, slaughterhouse, and fermentation wastewaters. Dr. Stover has extensive experience with various anaerobic treatment technologies including lagoons, suspended growth systems, fixed-film systems, upflow anaerobic sludge blanket reactors, and hybrid reactor designs. Dr. Stover has also conducted extensive research and development and process development activities with anaerobic systems.

Dr. Stover has extensive experience with biological aerobic thermophilic treatment processes including both industrial wastewater treatment and sludge digestion. Aerobic thermophilic projects have included treatability and pilot plant studies, concept and process engineering, detail design, construction engineering, startup and operator training, operations manuals, and operational troubleshooting services. A list of relevant technical publications on aerobic thermophilic treatment follows.

Dr. Stover’s graduate work at Oklahoma State University was concentrated in the areas of microbiology and biochemistry. His research and consulting experience has continued to center around the microbiological and biochemical aspects of wastewater treatment. Of particular interest has been his continued work in the area of identification and control of nuisance microorganisms, especially filamentous bacteria, during biological treatment. Every operational troubleshooting, problem solving, and operational process control project with biological treatment involves microbiological testing and identification. A list of relevant wastewater microbiology publications follows. Dr. Stover routinely performs microscopic analyses and identification of the microbiology associated with biological wastewater treatment plants.
