Abstract
Aerobic granular sludge involves microbial community, which allows simultaneous removal of carbon, nitrogen, phosphorus, and other pollutants in a single reactor. The feasibility of aerobic granular sludge has been extensively studied for implementation in wastewater treatment for municipal, domestic and industrial wastewater including palm oil mill effluent, livestock, leachate, dairy, textile and other complex effluents. This article reviews the application of aerobic granular sludge for nutrient, phenolic compound and heavy metals removal from municipal, domestic and industrial wastewater. It discusses the integration of aerobic granular bioflocs with membrane technology, microbial fuel cells and microalgae to enhance the efficiency of wastewater treatment. • Latest research on 2019 for aerobic granulation technology were reviewed. • Biological nutrient removal using aerobic granular bioflocs were covered. • Biosorption of heavy metals by aerobic granular sludge was extensively discussed. • Integration of aerobic granular sludge with membrane technology, microbial fuel cells and microalgae was detailed.
