Cliff Quay Sludge Pasteurisation Plant Control & Automation System

Project Description & Scope of Work


Control system and software design and development for a continuous batch process control of Sludge Pasteurisation Plant. System controlled by an Allen Bradley PLC interfaced to a PanelView. The control philosophy involved the sludge heating using heating and recovery coil heat exchangers to 72°C and holding the sludge for 30 minutes to kill pathogens for sludge disposal to land fill. Residual heat recovery was use to heat incoming ambient sludge with heat exchangers. Sludge flow and heat to digesters was also improved and managed.
