After implementing an optimization strategy, actual conditions closely correlate with <br />the optimal set -points for wastewater treatment. <br />Since implementing the BLU-X solution, the Cuxhaven treatment plant has shown a 26% <br />reduction in aeration energy usage, corresponding to 1.1 million kWh annually — enough <br />energy to power 64 homes for one year. In addition, all plant effluent concentrations <br />continue to be tightly maintained within regulatory compliance limits. <br />Statement of Work and Deliverables: <br />The purpose of a Discovery Project is to identify and quantify opportunities for treatment <br />optimization via the implementation of a BLU-X RT-DSS. In Phase 1: Discovery <br />Project, EmNet will complete the following scope of work: <br />1. Review Existing Data. Request and review information relevant to South Bend's <br />WWTP. As examples, some information requested may include: <br />• reports/studies <br />• plant size and basic specs <br />• influent/effluent data <br />• sludge treatment process <br />• nitrification/aeration process <br />• phosphate precipitation <br />• energy usage <br />• analytical data <br />• other constituents (fats, oils and grease (FOG), temperature, pH, etc.) <br />• biological parameters <br />• compliance constraints <br />• sensor and existing control system information <br />• current standard operational procedures <br />Page 4 of 6 <br />
