Abstract
Activated sludge is the most popular biological method for treatment of wastewater. This process has successfully eliminated detrimental environmental impacts, such as toxicity, persistent organic materials, depletion of oxygen, and formation of algal blooms. However, it is often considered as economically and environmentally unsustainable wastewater treatment technology. The advent of latest technologies and improvements in metagenomics and metaproteomics study has provided a detailed insight into the microbiome of activated sludge treatment system. The present chapter mainly deals with the microbial community present in activated sludges and its composition. The seasonal modulation of the microbial communities in activated sludge is also discussed in detail along with the abundance of different microbial groups and their role and physiological activities in activated sewage sludge are reviewed. Antibiotic resistance genes present in activated sludge have also been discussed in detail.
