Sustainable Approaches for Pollution Control: Bioelectrochemical Systems, Microbial Fuel Cell, and Microalgae-Based Wastewater Treatment Strategy

Sustainable approaches of wastewater treatment emphasize on clean technologies for large scale industrial effluents treatment. Feasible demonstration and commercialization of biomass-based treatment systems for waste treatment and value addition have been targeted by sustainable development. Value addition in terms of renewable electricity generation system, biomass recovery, biofuel production, and efficient sludge usage has been recommended in any new pollution compaction technique. Bioelectrochemical systems, microbial fuel cell, and microalgae-based wastewater treatment techniques have been the focus on the book chapter as its development focuses on synergistic waste treatment and resource recovery. This chapter summarizes the principle, mechanism, merits, and demerits of the chosen system in general. The specific industrial application in tannery, leather, and pesticide wash off water treatment has been discussed. Challenges of sustainable approaches toward commercialization have been discussed.
