Protecting Ballarat South’s Sludge Processing Plant and Pre-fermenter
The Ballarat South WWTP is an advanced treatment system that discharges high quality effluent to the Yarrowee River.
A recent upgrade to the plant included the installation of a new HUBER Strainpress® Sludge Screen to process primary sludge from the settled in the primary clarifiers.
The process includes a pre-fermenter to produce volatile fatty acids (VFAs) that feeds the main treatment process. The HUBER Strainpress® removes fine material and screenings prior to the pre-fermenter in order to ensure the pre-fermenter is free of such material that would otherwise cause it to be off line for cleaning. Cleaning of the pre-fermenter increases the use of associated carbon dosing and cost.
Key Benefits:
- Removal of fine material, screenings and plastics from the primary sludge screen
- Protection of the downstream sludge process with reduce maintenance costs, in particular to digesters and pre-fermenters
- Pressurised screen can be operated inline
- Proven in numerous sites across Australia
HUBER’s Strainpress® is used to screen both primary and waste activated sludge streams. Its main application is to be installed upstream of an anaerobic digester to remove debris prior to the digester.
