Real Time Aeration Efficiency for Wastewater Plants

Wastewater aeration requires 50% of the energy use in wastewater treatment plants. A real-time analyzer that measures aeration efficiency was developed with CEC funding and has been demonstrated with SCE funding at several wastewater treatment plants over a one-year period. To achieve the full benefit from this technology it is necessary to integrate the analyzer signal with the dissolved oxygen probe signal that currently controls the wastewater aeration blowers in all wastewater treatment plants.
