Abstract

Design considerations and operating procedures were investigated for nitrogen removal in an extended aeration-denitrification facility. Both past and present removal efficiencies were evaluated for the facility, along with capital and operating cost data. The findings of this research indicate that at very long detention times, significant nitrification and denitrification occurred in the plant without the use of chemicals. Overall nitrogen, BOD5, and suspended solids removals were extremely high. The significance of this research is that future plants may achieve high rates of nitrogen removal through innovative design and operating procedures without the use of costly chemicals. However, capital costs needed to achieve longer detention items will have to be evaluated for the individual plant.
