Project Information

The biosolids drying facility uses proven technology that is safe, reliable, efficient, and capable of delivering a consistent T1 grade of pelletised, dried biosolids;  the highest treatment grade of biosolids possible.

The Keppel Seghers HARD Pelletiser is an established and proven technology that relies on indirect heating to dry the biosolids and form stable pellets, maximising the beneficial reuse options. The dryers and main process equipment is fully enclosed to contain any odour.

The biosolids from the Black Rock Water Reclamation Plant are fed to the biosolids drying facility via a positive displacement pump and pipeline, bridging the distance between the existing belt press building and the facility, into enclosed buffer storage silos.

Deliveries from Barwon Water’s other water reclamation plants are received within the facility and blended with the material received from Black Rock Water Reclamation Plant and processed by the facility.

Following an EPA Works Approval Process and completion of design, construction commenced in Q3 2008 and the construction, commissioning and testing of the facility was completed in September 2012.

The 20-year contract to design, build and operate the biosolids drying facility has a net present value of $76 million at August 2007.
