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.
