Unrestricted entrance of waste water in the ecosystem & the transfer of microbial pollutants into persons & creatures necessitates the deployment of adequate purification equipment for microbial contaminants having higher degradation effectiveness. Inside the current study, a brief discussion about the major sources of water pollution, its stepwise major treatment methods. The treatment of wastewater in three distinct degrees: basic, secondary, and tertiary. The biodegradation of organic carbon, or BOD, is the most important aspect of wastewater treatment. The heterotrophic or carbonaceous bacteria in the water aeration tank are responsible for this. These bacteria absorb organic carbon molecules from the mixed liquid and utilise them for respiration or biomass growth. This will delves deeper into the various wastewater treatment systems, including tables that evaluate their uses, benefits, and drawbacks. It also tells you when to use which sort of treatment on certain waste streams. This data can assist close the gap between where the plant should be in terms of effluent quality and where it is now in terms of wastewater characteristics. Wet air oxidation, supercritical oxidation, activated sludge, incineration, aerated lagoons, trickling filters, stabilisation ponds, fixed-film reactors, & anaerobic degradation are some of the technologies used.
