Hydroflux Awarded Thermal Dryer Package for North West Treatment Hub Program

Sydney Water continues to support the rapid growth of new and existing communities in Sydney’s North West by delivering the North West Treatment Hub program. The program includes upgrades at Castle Hill, Rouse Hill and Riverstone Water Resource Recovery Facilities (WRRFs).

As part of its circular economy initiatives and to diversify reuse products generated from the wastewater, Sydney Water’s Riverstone WRRF will be provided with a carbonisation process to produce biochar from the digested sludge stream produced from the treatment process.

Hydroflux has been awarded the design, engineering and delivery of a thermal dryer package which will dry waste activated sludge prior to the carbonisation process.

“We are excited to be part of such an innovative project that will result in the circular use of biosolids in the form of biochar. This carbon rich material is valuable as it can be beneficially reused in agricultural and manufacturing processes,” John Koumoukelis, CEO of Hydroflux said.

“We will be providing a HUBER BT16 Belt Dryer capable of processing up to 18,700 t/a of dewatered sludge, to produce a final dried product of approximately 90% that will be further treated in the downstream carbonisation process,” he said.

“This is our second thermal dryer being delivered, the other being for the Wellington Sludge Minimisation Project in New Zealand. Globally, HUBER has delivered over 80 thermal dryer projects for municipal applications. As the Australian and New Zealand agent for HUBER Technology, we have access to HUBER’s global expertise in the field of biosolids treatment and on how to integrate a thermal drying into an advanced biosolids treatment facility or wastewater treatment process.”

Hydroflux offers a range of sludge drying solutions that can be used to further reduce the volume of sludge being transported offsite, reducing disposal costs. The drying technologies SOLSTICE® Solar Dryers, BT Belt Dryers and RotaDry® DISC Dryers.
