How it works
The activated sludge plant provides secondary treatment of the wastewater and is designed to remove nutrients (nitrogen & phosphorus) and provide some disinfection.
The effluent receives screening, flow measurement and odour control at the inlet works followed by biological treatment in two extended aeration tanks. Treated effluent is drawn off to a catch pond before it is discharged.
Waste mixed liquor is thickened on a gravity drainage deck and dewatered through a filter belt press in the biosolids handling facility.
How is the treated effleunt used?
All treated effluent is discharged via the Lake Macquarie Crossing to the Belmont ocean outfall.
All biosolids produced at the plant are beneficially used for mine site rehabilitation.
