Advanced biological treatment of wastewater: A concise review

Abstract:

Wastewater  is  a  by-product  of  industrialization  and  urbanization  processes.

Developed  countries   generate   more   wastewater  than   developing  and   less

developed countries. Even developed countries can't treat 100% of wastewater

produced. This study was aimed to investigate advanced biological methods for

wastewater treatment. It reveals that biological treatment is cost effective and eco-

friendly. Microbes are the best arms to combat pollutants. Metabolic engineering

of  microbes is  the  advanced strategy to  optimize  wastewater treatment. New

microbes  and  their  potentiality  must  be  investigated  in  future.  Metabolic

engineering in light of biofuel production utilizing wastewater as a resource must

be explored massively in future.
