Aeration Basin Control and Monitoring
Aeration control regulates oxygen delivery in wastewater treatment plants to support biological processes such as the activated sludge system. By managing dissolved oxygen levels, airflow rates and mixing intensity, operators promote effective breakdown of organic matter and nutrients. Real-time monitoring of DO, ammonia, nitrate and, in some cases, oxidation-reduction potential (ORP/redox) enables automated adjustments to blower speeds, valve positions and zone aeration, helping utilities maintain stable treatment performance, improve energy efficiency and meet effluent quality standards.
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.
Maintains proper DO and nutrient levels to ensure efficient biological processes like Biochemical Oxygen Demand (BOD) removal, nitrification and denitrification.
Aeration is the largest energy consumer in most plants; precise control reduces blower energy use and operational costs.
Continuous monitoring helps meet effluent quality standards for BOD, ammonia and nitrogen, avoiding fines and environmental impact.
Real-time data and trend analysis allow early detection of issues, reducing downtime and improving reliability.
