Is your organization contemplating nutrient treatment upgrades? Do you want to learn more about what it would take to upgrade your plant?

In 2020, the Oro Loma and Castro Valley Sanitary Districts converted its existing activated sludge process to nitrify and denitrify average flows of 16 million gallons per day. The $24.7M project took two years to build and is achieving less than 10 mg/L of Total Nitrogen in the effluent. Come hear the story of the project, photos from construction, what went right, and lessons learned that you and your organization can benefit from.
