Operating to Achieve TIN <0.5 mg/L

Abstract

The LOTT Clean Water Alliance completed the first phase (two of five trains) of an upgrade to the secondary process at its Budd Inlet Treatment Plant in 2022 to improve the efficiency of nitrogen removal. The entire project was completed in early 2023. The upgrade included improvements to nitrified recycle pumping, added two swing zones to each train, added large bubble mixing in the dedicated anoxic zones as well as the swing zones, replaced two single stage centrifugal blowers with turbo blowers (to compliment the one turbo blower in use for over 10 years), and added ammonia-based aeration control (ABAC). After one year of operation, the effluent TIN of < 0.5 mg/L was substantially lower than the 3 mg/L seasonal TIN limit while also decreasing energy and methanol usage
