Energy Efficiency Comparison: AGS–SBR vs Activated Sludge SBR
Energy consumption dominates lifecycle costs in sewage treatment. While both systems rely on aeration, how efficiently oxygen is used defines performance.
Aeration as Compensation vs Necessity
Activated Sludge SBRs use aeration to maintain suspension, nitrification, and process stability. AGS–SBRs use aeration only when biologically required.
Lower Oxygen Demand
Simultaneous nitrification and denitrification in AGS reduces oxygen demand compared to sequential treatment in Activated Sludge SBRs.
Reduced Mixing and Pumping
AGS–SBRs eliminate return sludge pumping and reduce mixing energy due to rapid settling and batch operation.
Lifecycle Energy Advantage
AGS–SBRs typically demonstrate 20–40% lower energy consumption compared to Activated Sludge SBRs achieving the same or sometimes higher compliance objectives.
Energy efficiency is not achieved by equipment alone—it is achieved by aligning biology with process design. AGS–SBRs do this inherently.
