A few weeks ago, while reviewing data from one of our primary sludge fermentation runs, I noticed how a small operational change, such as a tweak in alkalinity dosage or a slight increase in Fe addition, can shift P-release in fermentation substantially. It reminded me that in process engineering, as in career development, small, intentional changes can create lasting impacts.
This summer, I joined DC Water’s R&D team at the Blue Plains Advanced Wastewater Treatment Plant. Our focus was operating a pilot-scale primary sludge fermentation system to explore ways of reducing methanol use at the plant and supporting full-scale PdNA implementation.
The work was hands-on, unpredictable, and sometimes messy. From sludge conveyance to reactor troubleshooting and process optimization, our team gained a deeper understanding of the factors that drive fermentation performance. It was also deeply rewarding. Every discussion with my teammates taught me something new about applied research, teamwork, and persistence.
My takeaway? The path to better technologies is built on curiosity, persistence, and learning from every trial, whether successful or not. To my teammates Mekhi Boulware, EIT, and Sophia Davis, thank you for making this experience so much fun. To my mentors Isaac Avila, Haydee De Clippeleir, and Ngo, Khoa Nam, I truly appreciate all the opportunities I had to learn from you.
Here’s to the next experiment, the next dataset, and the next step forward!
