Interests
Dr. Speitel's teaching interests include biological treatment processes, disinfection by-product formation and control, adsorption, microbiology, and treatment plant design. His research focuses on hazardous chemicals, especially biodegradation and adsorption as applied to the treatment of drinking water, ground water, contaminated soil, and contaminated gas streams. Related areas of interest are formation and control of halogenated disinfection by-products, computer modeling of treatment processes, optimal design of treatment processes, and microbial processes in the subsurface. Recently funded research addresses formation of disinfection by-products in drinking water treatment during chloramination, cometabolism of trihalomethanes in drinking water biofilters and distribution systems, adsorption of arsenic on granular metal oxides, in situ biodegradation of perchlorate, biodegradation and adsorption in activated carbon columns, and, aerobic biodegradation of chlorinated solvents in hollow fiber membrane reactors for ground water and air treatment. For additional information, see Dr. Speitel's home page.
