Operators across the APAC region have long struggled with the limitations of conventional aeration control systems. Mass-flow-based aeration control represents a paradigm shift.
From Manual Control to Intelligent Aeration:
Many rely on manual valve adjustments, outdated dissolved-oxygen control strategies, or blower systems that cannot respond dynamically to process changes. The result is inefficiency: basins fighting each other, over-aeration, high blower pressure, and elevated energy consumption. But then there is Mass-flow-based aeration control.
The VACOMASS® system uses an integrated set of airflow meters, control valves, and intelligent software to deliver precise oxygenation at the lowest possible energy input. Instead of manipulating pressure, the dynamic control algorithm calculates the exact mass of air required for each aeration zone in real time —then automatically adjusts the valve position.
Pump and Valve are the distributors of Binder Group products for ANZ region.
For operators, the practical benefits are immediate:
- • No more manual tuning or constant intervention
- • Stable DO-control even during major load variations
- • Improved nitrification/denitrification performance
- • Reduced blower pressure and lower specific energy demand (kWh/kg N removed)
- • Greater resilience to seasonal transitions
One of the system’s hidden advantages is visibility. VACOMASS® provides operators with live, high-accuracy airflow data, something many plants have never had before. That visibility enables smarter operational decisions, proactive maintenance, and energy benchmarking.
As utilities increasingly invest in digital optimisation, mass-flow-based control has become a foundation technology: easy to integrate, cost-effective, and proven across thousands of operational hours globally.
For plants aiming to reduce energy usage and stabilise biological performance in 2026, aeration control is the highest-impact improvement available.
