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 ...
Activated sludge is a process for treating sewage and industrial wastewater using air and a biological floc composed of bacteria and protozoa. The process involves introduction of air or oxygen into a mixture of primarily treated sewage or industrial wastewater combined with organisms to develop a biological floc which reduces the organic content of the sewage.

If the effluent, the treated wastewater produced by a treatment plant, has a high content of organic pollutants or ammonia, it will demand more oxygen from the water and leave the water with less oxygen to support fish and other aquatic life. Organic matter and ammonia are "oxygendemanding" substances.
An oxidation ditch is a large holding tank in a continuous ditch with oval shape similar to that of a racetrack. The ditch is built on the surface of the ground and is lined with an impermeable lining. This allows the waste water to have plenty of exposure to the open air for the diffusion of oxygen.
