Abstract:

Startup and ongoing operations of a new BNR plant has proven to be a tremendous learning experience for plant staff. Biological phosphorus removal, volatile fatty acids (VFA's), sludge fermentation, anaerobic zone P release and molasses feed were some of the new concepts that the staff had to become familiar with. This paper will discuss the design and operating experience gained in the 2.5 years since the new plant was commissioned. Some unique data will be presented to document process performance, including VFA's and phosphorus at key points, seasonal variations, and the effect of process upsets on BNR performance.
