This is a technically skilled, professional, state certified position responsible for successful continuous, real-time operations of a 15.5 MGD advanced secondary wastewater treatment plant. The Liquids Operator is responsible for operational control and maintaining plant processes within the facility's Wisconsin Pollution Discharge Elimination System (WPDES) permit. Systems include:
• Sanitary Collection Systems (monitoring and troubleshooting the operation of 15 lift stations) • Preliminary Treatment Systems (fine screen and wash, vortex grit removal and classification). • Primary Treatment • Secondary Treatment Systems (conventional activated sludge, with single stage nitrification and secondary clarification). • Disinfection Systems (pathogen destruction with chlorination and dechlorination) • Solids Thickening (dissolved air flotation, primary and receiving station processing). • Digestion (anaerobic digestion, methane production, gas compression, storage/use). • Chemical phosphorous precipitation.
Liquids Operator responsibilities involves the comprehensive monitoring, testing, and control of the chemical, physical and biological processes at the wastewater treatment plant. The operator completes analytical testing to maintain plant processes and for regulatory reporting requirements. Operators control equipment, pumps, valves, chemicals, etc. in order to affect efficient, compliant discharge effluent and digestion product. Work is performed under general supervision of the Operations Manager.
ESSENTIAL JOB FUNCTIONS
