Abstract

This research investigated the growth and control of specific filamentous organisms at bench scale and developed a database of selector design and operating data from full-scale facilities. It examined the relationship between process parameters and settleability control and identified significant process variables affecting settleability control in three plant types—short-MCRT with anoxic or anaerobic selectors, short-MCRT with aerobic selectors, and long-MCRT—and provides design and operating ranges based on single-variable regression analysis of a large database of full-scale plant data. The computerized selector diagnostic tool can be used to retrieve recommended design and operating ranges based on user input. (MS Access is required to run the diagnostic tool).

As of February 2020, the web tool is no longer available.
