Abstract

© 2012 by World Scientific Publishing Co. Pte. Ltd. All rights reserved. The basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treatment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed fromwastewater. The secondary stage uses biological processes to further purify wastewater. Sometimes, these stages are combined into one operation. This chapter introduces the biological treatment processes for the wastewater treatment. The technological topics covered are: role of microorganisms in treatment, aerobic suspended growth, aerobic attached growth, anaerobic attached growth, and treatment kinetics.
