Abstract
Population growth in urban areas is leading to an expansion in industrial development, which in turn creates increased volumes of wastewater with ever more complex compositions. The wastewater that is generated is discharged into water sources that supply drinking water to other urban areas, causing higher levels of pollution. One option for the treatment of water and wastewater is the use of biological processes, which offer certain advantages over other common treatment technologies. The organic contaminants to be destroyed are used and transformed by bacteria or other organisms as a source of food. Thus the water/wastewater treatment process is used to dispose of waste in a non-toxic and sanitary manner. This chapter discusses the major biological options for water and wastewater treatment.
