Sludge Pond Reclamation and Dewatering

Water Treatment Dewatering Sludge Dewatering Hazardous Waste Recycling Remediation Environmental Civil

Recovery and removal of sludge from two settlement ponds. The less viscous liquid component of the sludge was removed via a hydraulic slurry pump and transported via pipeline for processing in Synergy’s on-site two-stage sludge dewatering system, enabling the separation of the sludge into two products; solids and water.

The second method involved stabilisation and reclamation of the more viscous component of the sludge, using two 20-tonne excavators and transporting the sludge to stockpiles for dewatering using two Marooka 10-tonne tracked dump trucks and a Sludge Conditioning System (SCS). The SCS removed particles greater than 100 microns in a process consisting of two desander hydro-cyclones and a twin deck lineal motion accelerator screen, with ten de-silting hydro-cyclones and a second twin deck lineal motion accelerator screen.

Following removal of water, the stabilised sludge was transported offsite for beneficial reuse as agricultural fertiliser in the region.
