This is a technically skilled position responsible for the successful, continuous, real-time operation of solids dewatering processes and final deposition procedures in accordance with within the facility's Wisconsin Pollution Discharge Elimination System (WPDES) permit and local, state, and federal standards for municipal wastewater treatment residuals and agricultural land application practices. Systems include:
• Inventory Systems (include secondary digesters, digested sludge wells, filtrate delivery and storage system, water treatment residuals delivery and storage, and the biosolids conveyance system) • Dewatering Equipment (belt filter presses, chemical feed and mix systems, biosolids storage and out loading (containment and out loading systems that utilize forklift and payloader operations to maintain physical inventory).
Operations work involves monitoring, analytical testing, and control of all phases of solids dewatering processes. Work includes maintaining process inventories, establishing chemical and sidestream volumes and flow rates. The operator collects and analyzes samples to evaluate belt filter press performance and control process variables to ensure efficient operations. The operator is responsible for the collection of regulatory compliance samples according to state and federal laboratory procedures and protocols. This position reports to the Wastewater Operations Supervisor.
