This paper will follow on the previous presentations by these co-authors regarding design and startup of this unique biological treatment system and present an overview of the first four years of plant operations. The plant was placed into operation in late 1998 and treats a process wastewater flow of up to 280 gpm from the second largest coke plant in North America. The treatment system includes oil and tar removal, equalization, free ammonia distillation, and biological nitrification and denitrification. After a brief review of the system design and operating strategies, the following items will be addressed in the presentation:

Overall system performance, including feed and effluent quality;

Activated sludge operating parameters including temperature, pH levels, MLSS/MLVSS, nutrient phosphorus levels, alkalinity levels, F/M, and sludge age.

Control of sludge wastage rates and MLSS/MLVSS levels, sludge age, F/M levels, and clarifier sludge blanket heights;

Trends in effluent Benzo(a)Pyrene levels, and measures implemented to control this parameter safely under permit limits; and,

Chemical usage in the bio-plant including alkalinity, defoamer, phosphorus, polymer, and others.
