PULLMAN, Wash. — A leading researcher in one of the largest environmental consulting and engineering firms in the United States will speak on “Modeling Biological Processes — Evolving Applications’’ as part of the 2001 Kappe Lecture series.

The lecture will be at 3:10 p.m. Monday, Feb. 4, in Todd 216 on the Washington State University campus. A reception will follow.

Glen T. Daigger, senior vice president of CH2M Hill, has successfully combined academics and practical careers in environmental engineering in his quest to improve the processes used for wastewater treatment. He has been involved with leading researchers in the development and full-scale application of many principal biological treatment innovations during the 1980s and 1990s. These included biological selector technologies to control settling of sludge, biological nutrient removal technology, and advanced, fixed-film processes such as combined trickling filter/activated sludge processes.

Daigger has taken what he has learned from serving in a variety of positions at CH2M Hill to educate future environmental engineers as professor and chair of the environmental systems engineering department at Clemson University. While at Clemson, he helped organize the interdisciplinary School of the Environment, which combined the departments of environmental systems engineering, environmental toxicology, and geosciences.

Daigger’s lecture will focus on biological process modeling. Biological processes to treat wastewater are complex, and their behavior is often counter intuitive. Biological process models provide tools to methodically consider the interactions between various system components and the resulting overall behavior of the system.

The Kappe Lecture Series, through the American Academy of Environmental Engineers, brings leading researchers in the environmental engineering field to college campuses.
