Abstract
The objective of this chapter is to put forward an overview of biodegradation characteristics of wastewaters by emphasizing the significance of COD fractionation. Recalcitrant COD fractions of effluents can be used as a tool to evaluate whether discharge standards can be met with a prescribed biological treatment. Moreover, the appropriate type of biological treatment applicable to the wastewater under investigation can be addressed and the performance of an existing biological treatment system can be appraised with reference to inert COD fractions. Besides recalcitrant COD fractions of segregated industrial effluent streams can be regarded as an essential input of a sound industrial wastewater management strategy adopting minimization at source philosophy. Last but not least, data on COD fractions can be used as a solid source of information for modelling studies that define the design and performance of biological treatment systems. In this context, COD fractionation data on a wide spectrum of activities ranging from various industrial sectors to hotels is presented. Segregated industrial wastewater streams together with domestic sewage and end-of-pipe industrial effluents are evaluated in terms of their biodegradation characteristics.
