Biological Treatment of Waste
Waste treatment, additionally referred to as sewage treatment, is the removal of polluting impacts from sewage, before they enter regular waterways, for example, streams, lakes, estuaries, and seas (Mintenig et al. 2017). Institutions, offices, industries, and residences are the main sources of waste and it can be mixed with ground water and surface water. If the waste is not treated before releasing into water bodies, it would impact natural and human well-being, for example, liberation of odors, the consumption of dissolved oxygen, and therefore the unleash of nutrients, harmful contaminants, and pathogens (Droste and Gehr 2018).
