Pilot scale study on characterization and performance of aerobic granular sludge to treat domestic wastewater
Aerobic granular sludge (AGS) is a wastewater treatment technology that is known for having unique advantages such as great settling ability, high biomass level, good shock resistance, and able to withstand high organic loading rate (OLR) and toxic pollutants. Since studies on AGS development are mo...
