Precision Aeration System

Wastewater biological treatment is a dynamic process, where factors such as time delay, nonlinearity, and changing conditions make precise dissolved oxygen (DO) control challenging for conventional systems. With over 10 years of expertise, the IACS team has developed advanced models and optimized algorithms to achieve dynamic compensation and adaptive control for stable and efficient operation.


The IACS system continuously monitors DO levels in real time and automatically adjusts airflow when deviations occur, ensuring accurate and stable control. By optimizing valve operation and blower pressure settings, the system improves aeration efficiency and significantly reduces energy consumption.

Through the effective application of the IACS intelligent control system, wastewater treatment plants can achieve the following benefits:

  • Stable and demand‑based dissolved oxygen (DO) control, enhancing process robustness and improving resistance to shock load variations;
  • Rapid response to dynamic DO setpoint adjustments, ensuring more stable effluent quality and reducing the risk of non‑compliance;
  • Significant reduction in aeration energy consumption, with typical energy savings ranging from 10% to 30%;
  • Enhanced plant automation and digitalization, supporting smart wastewater management and aligning with carbon reduction and sustainability goals.
