A profound understanding of environmental processes and biotechnological solutions of environmental problems are siginificant contributions to a sustainable development.

This volume is the first of three volumes on environmental biotechnology and summarizes biological and engineering aspects of wastewater treatment processes for municipalities and industry. It includes the fundamental processes for aerobic and anaerobic carbon degradation, nitrogen and phosphorus elimination, mathematic modeling of processes, followed by detailed descriptions of commonly accepted technical solutions for wastewater purification.
