How do you aerate efficiently when DO differs from zone to zone?

To achieve energy efficient—and therefore cost-efficient—aeration, your system must distribute process air from blowers at a minimum air pressure in the manifold, and with minimum pressure loss across each air valve.

Hach’s RTC-MOV Software can independently adjust air valve positions to achieve DO setpoints in up to 16 different zones while sending a total airflow setpoint to the existing blower control panel. Each valve’s position is determined by comparing a calculated airflow setpoint to the measured airflow for the zone. Airflow setpoints are calculated using the difference between measured DO and the DO setpoint (cascade controls), which can be input manually or automatically from an ammonia-based aeration controller. To ensure the most efficient distribution of air, the system’s controller evaluates the position of each air valve and provides that one valve is as open as possible in order to minimize system friction losses. The result is reduced costs and maximum available process air where it is needed most.

Claros Process Management solutions for nitrification/denitrification like RTC-MOV are designed to make the most of your plant’s real-world conditions by transforming every uncertainty into an opportunity for measurement, responsive action, and savings.
