Edit Profile

Dr Detlef Knappe


Dr Knappe is interested in drinking water quality and treatment, water reuse, organic micropollutants, development of water treatment processes for persistent organic pollutants, fate of organic pollutants in solid waste landfills

  • Ph.D., Environmental Engineering, University of Illinois, Urbana-Champaign
  • M.S., Environmental Engineering, University of Illinois, Urbana-Champaign
  • B.S., Civil Engineering, University of Illinois, Urbana-Champaign

Detlef Knappe is a Professor of Civil, Construction, and Environmental Engineering at NC State University. He received his BS, MS, and PhD degrees from the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign, and he joined the NC State faculty in 1996. He has conducted research on water treatment processes for over 20 years, and current research efforts focus on (1) developing and evaluating physical-chemical treatment processes for the control of disinfection byproduct precursors and trace organic compounds (taste and odor causing substances, carcinogenic volatile organic contaminants, 1,4-dioxane, perfluorinated compounds, endocrine disrupting chemicals, antibiotics, and other pharmaceutically active compounds), and (2) overcoming gaps between the Clean Water Act and the Safe Drinking Water Act by developing information about the effects of reactive and unregulated wastewater contaminants on drinking water quality and treatment.

Funding agencies that have supported or are currently supporting his research include the U.S. Environmental Protection Agency, the National Science Foundation, the Water Research Foundation, the North Carolina Water Resources Research Institute, and the North Carolina Urban Water Consortium. He served as Associate Editor for the journal Water Science and Technology, is a Topical Editor for the Open Access Journal Drinking Water Engineering and Science, and is a member of the American Water Works Association Standards Committee for Activated Carbon.

Detlef Knappe and his students have been the recipients of numerous best paper, best poster, and best thesis awards. He is a recipient of the NCSU Outstanding Teacher Award, the Bill Horn Kimley-Horn Faculty Award for excellence in graduate and undergraduate teaching and other accomplishments at NC State University, and the Young Civil Engineer Achievement Award from the University of Illinois.
