Emergency Treatment of PFAS Contaminated Flood Water
City Water Technology was engaged by Veolia Environmental Services to provide specialist process, project management and operations support for an emergency PFAS water treatment plant in Sydney.
CWT assisted Central Highlands Regional Council with the Blackwater WTP Upgrades project undertaken to address ongoing dirty water issues and customer complaints in the drinking water system.
Blackwater WTP had a history of manganese and organics in its raw water supply that was not adequately addressed by the treatment processes at the WTP. This had led to an ongoing stream of customer complaints and a local political issue regarding the quality of the treated water.
Based on typical source water quality in the area, options were evaluated for treating manganese and organics in order to provide the best balance of cost, treated water quality and operability. Upon completion of the assessment, the WTP was upgraded to include further treatment processes for manganese removal, including:
CWT also assisted in directing network flushing to remove manganese particles accumulated in the reticulation.
CWT’s optimisation and WTP upgrade solutions provided the client with improved water quality outcomes, leading to increased customer satisfaction in line with their agreed levels of service.
