Dr. James Englehardt, P.E., is Professor of Environmental Engineering, appointed 1992. Before receiving his Ph.D. from the University of California, Davis, Dr. Englehardt led filtration research projects for Johns Manville Corporation (1983-1987), and supervised water treatment laboratory development and field service for the Western Filter Company (now GE Water) (1978-1980). He currently directs the Water Quality Engineering Laboratory, focusing in part on reversing climate change. In particular, the group recently developed the first energy-positive system to manage municipal water and wastewater, supported by the National Science Foundation (NSF), the U.S. Environmental Protection Agency (EPA), and industry partners. This net-zero water system recycles 100% of municipal wastewater, while mineralizing organic and microbial contaminants to carbon dioxide, and saving more energy (for heating hot water) than it uses in treatment and conveyance of water and wastewater combined, at a cost equivalent to conventional technology. Further, the group is now developing a new net-zero water process to cut energy demand in half. Implemented nationally, these processes can save percent levels of total US primary energy demand.

Dr. Englehardt serves on the EPA Science Advisory Board, and as Associate Editor for the journals PLoS ONE and ASCE-ASME Risk and Uncertainty in Engineering Systems. Awards include the WaterReuse Association 2018 Award for Excellence in Transformation Innovation, two Johnson A. Edosomwan Outstanding Publication Awards, University of Miami; the Science Advisor’s Award, EPA National Center for Environmental Assessment; the Robert C. Barnard Environmental Science & Engineering Award for Advances in Risk Assessment, American Association for the Advancement of Science and EPA; and two University of Miami Eliahu I. Jury Awards for excellence in research.
