1 Nutrient Concentrations in Wastewater Treatment Plant Effluents in Alabama AWPCA CONFERENCE. HUNTSVILLE, ALABAMA. AUGUST 4, 2015. Presentation Outline Explanatory Background Compelling Data and Necessary Assumptions Riveting Data Analyses Intriguing Case Studies Shocking Conclusion Welcome to the TK Inn! ECHO Facilities Search Returns Search Criteria Data for 114. Facilities About the Data 111 POTW Facilities Period of Record: January 2012 March 2015. Monthly Averages for Flow, TP, NO2+NO3-N, and TKN. TN = NO2+NO3-N + TKN. TP and TN Loads are reported values in ECHO. Below Detection Limits = of lowest reported value About the Facilities Average Monthly Average Flow = MGD. Monthly Average Flow Range: MGD. Median Average Monthly Flow = MGD. 10 Stabilization Lagoons 3 Hydrograph Controlled Release Systems Total Phosphorus - TP. effluent Concentration Range: mg/L. Average Monthly Average Concentration: mg/L.
