Nutrient regulations in the United States are becoming more prevalent and more stringent. The Sheboygan Regional Wastewater Treatment Plant (RWWTP) is currently assessing nutrient removal improvements to their biological nutrient removal facility to achieve future, more stringent discharge permit requirements. The historic operational data contained limited influent nitrogen values, making a true variability evaluation with a process like a Monte Carlo simulation difficult. An evaluation was completed using the distribution of influent biochemical oxygen demand (BOD) and total phosphorus (TP) at three different influent total kjeldahl nitrogen (TKN) values (average plus and minus one standard deviation). By running over 100 simulations, a distribution of ferric chloride required to meet a phosphorus discharge limit of 0.6 mg/L was developed that closely matched the measured yearly ferric chloride requirements. Different nutrient removal improvement scenarios were then assessed, and process and operational changes recommended based on the results.
