A New Era In Blower Control Efficiency

Source: Aerzen

A common misconception among wastewater plant managers is that pressure-based blower controls remain an industry “best practice” for aeration. The problem is this approach was developed during an age when most blowers were constant speed machines with outputs that could only be governed by the manipulation of inlet valve position or header pressure. Newer self-tuning, airflow-based control systems save energy, improve effluent, and reduce greenhouse gas emissions.
