Replacement Centrifuges to support 126 MLD Potable Water Production.
MTL led the project team for Watercare’s Sludge Dewatering Centrifuge Upgrade at the Huia Water Treatment Plant. The upgrade saw the replacement of the existing Centrifuges with new higher capacity ‘fully automated’ Decanting Centrifuges and Thickened Sludge Feed system upgrades to support 126 MLD potable water production. A staged installation of the Centrifuges was required to ensure the Sludge Dewatering Plant remained operational throughout the upgrade. Detailed staging installation methodologies were prepared by MTL to manage the works within the constrained site and to minimise operational disruption to the Sludge Dewatering Plant.
The two new higher capacity Centrifuges were successfully installed with minimal disruption to the Sludge Dewatering Plant. Both centrifuges are currently in operation.
