A meat processing plant and a tannery discharge to the plant along with residential and commercial wastewater. Automatic control has been provided for DO control, primary clarifier sludge withdrawal, return activated sludge, waste activated sludge, thickened activated sludge and this summer for anaerobic digester transfer, heating and mixing. Live data is stored and used to monitor and modify plant-operating parameters. This paper will present real-time experiences starting with the development of the control system and the strategies used to control critical process operations, and ending with the on-site start-up and tuning of the controls.
