The increase in human activities has exploited the environment way beyond the limits. Xenobiotics (pollutant) have been introduced into the environment due to such activities. Water pollution, due to discharge of untreated water from the industries into the water bodies has become a rising issue in today’s world. This has resulted in development and growth of harmful microbes that further causes emergence of diseases. The answer to this problem is Wastewater treatment process (WWTP) that converts the harmful waste effluent into less harmful effluent before discharging it into the environment. WWTP includes aerobic, anaerobic and anoxic processes which help in removal of nitrogen and phosphorus, as they act as major source for eutrophication in the water bodies. Further organic and inorganic particles are also removed. Even though, the technology has raised but still further research is required. Application of omic tools can provide a better understanding of the WWTP. The catabolic reaction of inorganic and organic compounds can be explained thoroughly by applying genomics, proteomics and transcriptomics. The current review gives a vision about the different -omic tools that provide information in the microbes involved in WWTP and their metabolic reactions.
