Biological Wastewater Treatment Process - an overview ~ In biological wastewater treatment process, the part of chemical oxygen demands (CODs) removed is converted into biosolids, which makes up sewage sludge.Sewage sludge usually represents 1–2% of the treated wastewater volume (Fig. 1.1).As per UN-Habitat's statistics, the existing wastewater treatment plants (WWTPs) in the United States, for instance, generate over 6.5 million tons of dry .

Biological and Chemical Wastewater Treatment Processes ~ This chapter elucidates the technologies of biological and chemical wastewater treatment processes. The presented biological wastewater treatment processes include: (1) bioremediation of wastewater that includes aerobic treatment (oxidation ponds, aeration lagoons, aerobic bioreactors, activated sludge, percolating or trickling filters, biological filters, rotating biological contactors .

Biological Wastewater Treatment - an overview ~ Biological wastewater treatment is designed to degrade pollutants dissolved in effluents by the action of microorganisms. The microorganisms utilize these substances to live and reproduce. Pollutants are used as nutrients. A prerequisite for such degradation activity, however, is that the pollutants are soluble in water and nontoxic.
