Aeration Basin Control and Monitoring

Dissolved Oxygen (DO) monitoring is critical in aeration basin control because it directly impacts the biological treatment process. Microorganisms in the aeration basin require oxygen to break down organic matter and perform nitrification (converting ammonia to nitrate). If DO levels are too low, microbes become stressed, leading to incomplete treatment and potential permit violations.

Ammonia and nitrate monitoring are used to indicate the effectiveness of biological nutrient removal processes. Monitoring these compounds enables operators to adjust aeration rates, maintain process stability and ensure compliance with stringent nutrient regulations, ultimately resulting in reduced energy costs.

Robust data integration capabilities allow for aeration basin monitoring data to be shared with a SCADA system or utility platform for improved situational awareness. Dashboard views and immediate alerts for abnormal conditions (e.g., low DO, high ammonia) allow quick corrective action, minimizing risk of permit violations.

Early detection of rising flows, blockages or unexpected influent composition changes enables operators to act quickly—reducing the risk of overflows, bypass events and environmental releases during dry- or wet-weather conditions.

Real-time flow and water quality insights help operators fine-tune chemical dosing based on actual loading conditions, improving process efficiency, protecting biological treatment and reducing overall chemical use.

Accurate, continuous influent data strengthens reporting, supports pretreatment program oversight and helps ensure treatment processes remain aligned with evolving regulatory requirements and effluent permit conditions.

Continuous monitoring of key parameters and trends provides early warning of abnormal conditions such as shock loads, industrial spills or toxicity events, enabling rapid intervention and preventing downstream process upsets.
