Using Food-To-Microorganism Ratio (F/M) and Solids Retention Time (Srt) to Control Nitrification at a Coke Plant
Abstract
This paper presents a case history of a North American coke plant to show how food-to-microorganism ratio (F:M) and solids retention time (SRT) can be used to control nitrification in an activated sludge system. The case history reviews a nitrification upset that occurred in 2014 and the analysis used to determine the cause and correct the problem. The paper also presents a troubleshooting process to help operators find early warning signs of potential upset conditions, as well as how to deal with upsets when they occur.
