• The activated sludge process is the most commonly used biological wastewater treatment process in the world. Activated sludge can biodegrade many organic pollutants, oxidize and remove reduced nitrogen compounds and promote the enhanced removal of phosphate from municipal and industrial wastewaters. Solid backgrounds in process engineering and microbiology are required for the diagnosis, control and resolution of common activated sludge process problems such as deterioration of settling properties, foam formation and loss of specialized organisms.

  • David Jenkins

    is Professor Emeritus of Civil and Environmental Engineering at the University of California at Berkeley where he taught and conducted research from 1960 to 1999. His interests are in wastewater treatment processes and water chemistry. He is an Honorary Life Member of IWA and WEF and member of the US national Academy of Environmental Engineering. Dr. Jenkins is the recipient of numerous awards that include the IWA Global Water Award and the Samuel Harry Jenkins Award. From WEF he has received the Fair, Camp, Eddy, Pohland and Gasgoine medals. Professor Jenkins continues to be professionally active in consulting, writing and teaching.

  • Steven Leach

    is a senior staff scientist with Novozymes Biologicals, Inc. He has more than 30 years of experience with wastewater biology, including fermentation, filament identification, treatment process evaluation, and onsite analysis during upsets, chlorination, and recovery. He has worked on the installation and start-up of over 20 fixed-film reactors units throughout the country. Steve is widely recognized for his expertise in identifying filaments and protists. He has completed onsite visits to wastewater treatment plants throughout North and South America, Europe, and Asia.
