Phosphorus (TP) removal is achieved with chemical precipitation and performance has been consistently good with effluent TP averaging less than 0.02 mg/I during the 4th quarter 2023.Therefore, no further review of TP operation is included. Optimization Report Recommendations The optimization report was prepared in 2020 based on data from January to September of 2020. Operating parameters at the time are shown in Table 1 below.

Optimization Implementation During the 4th quarter of 2023 the overall performance of the Siler City WWTP has been very good with average effluent BOD of 0.22 mg/I, and Ammonia of 0.23 mg/I.The influent BOD has remained relatively f Town of Siler City-Siler City WWTP EMC SOC WQ S22-033 Quarterly SOC Progress Report 4th Quarter 2023 Please accept this submittal as a quarterly progress report for the work and activities for the Town of Siler City under the Special Order By Consent.
