MICHAEL H. GERARDI holds an MS in biology from James Madison University and chaired the Water Environment Federation task force responsible for the development of its specialty publication, Wastewater Biology. He has authored more than ninety technical publications and has provided wastewater microscopy and consulting services for numerous municipal and industrial wastewater treatment plants. He is currently responsible for the development and presentation of the wastewater biology courses at Penn State.
For operators and technicians responsible for the daily operation of anaerobic wastewater digesters, Gerardi reviews in detail the bacteria used in such systems, their activity, the operational conditions that affect anaerobic digester performance, operational problems, troubleshooting, and corrective measures for process control. He specializes in wastewater biology. Annotation ©2003 Book News, Inc., Portland, OR
