The quantity and quality of waste generated and discharged into natural water bodies is a topic of serious concern. Consequently, there is a need for different strategies to address wastewater treatment and subsequent reuse, especially in arid and semi-arid areas where water shortages are the rule. Biological treatment processes constitute crucial tools in the biodegradation of organic matter, transformation of toxic compounds into harmless products, and nutrient removal in wastewater microbiology.

The activated sludge process is one of the most versatile and commonly used wastewater treatment systems in the world. In the past, when industrial wastewater treatment focused on removing biological oxygen demand and suspended solids, waste water plants needed different processes and technology. The shift to the activated sludge process means environmental engineers must build new treatment plants and retrofit old ones. In this compendium, the editor, an experienced and well-published scientist in the field, has brought...
