Mid North Coast, NSW
Digestor Desludging


The digester tank at this food processing facility was nearing capacity and required urgent maintenance dewatering. Dredging Solutions was engaged to remove the in-situ materials with small-footprint equipment suitable for the scope of the project.

Our Approach:

Sludge was mixed and pumped into the Feed Averaging Tank (FAT) before being dewatered using our containerised Vitone V9 centrifuge. The resulting dewatered sludge cake was loaded onto trucks for beneficial reuse at a local site.


Concerns around the digester overflowing were resolved through the effective pumping and removal of sludge from the digester tank well within the desired time frame. The dewatered solids were then loaded directly onto trucks for transportation to a nearby farm for land application in line with the NSW Biosolids Guidelines.
