Automation of Biological Nutrient Removal at the Mukilteo WWTF

The project addressed a need to reduce nitrogen in the final discharge stream at the Mukilteo Wastewater Treatment Plant by aiming to develop an automated controls strategy for secondary treatment. Using current and historical biological treatment data, the work was intended to develop a calibrated process model and evaluate control approaches that could fit within the plant’s existing infrastructure. The project aimed to produce a technical memo, preliminary process and instrumentation drawings, and a cost analysis to help assess potential operational improvements and savings.
