Sydney Water chooses Veolia Hydrotech™ Drumfilter technology

Hydrotech™ Drum Filter

Veolia Water Technologies Australia is pleased to announce the award of a contract for the design, supply, and commissioning of 20 Hydrotech™ Drum Filters for mechanical primary treatment at two of Sydney Water’s treatment plants — St Mary’s Water Recycling Plant and Quakers Hill Water Recycling Plant — in New South Wales. The upgrade is part of Sydney Water’s Lower South Creek Treatment Program. 

20 Hydrotech™ Drum Filters are installed at Stavanger, Norway, for primary treatment

With a move towards energy recovery and energy efficiency in wastewater plant design around the world, the first step of primary separation has become very important for two reasons — a higher TSS removal in the primary step reduces the load on the secondary treatment process (reducing power requirements and operating costs) and increased amounts of primary sludge entering the downstream sludge treatment or biogas recovery stages (such as digestion and/or thermal hydrolysis) will increase energy recovery.

Before and after treatment with a Hydrotech™ Drum Filter

This project continues the excellent experience Veolia has gained over the last 10 years in utilising Hydrotech™ Drum Filters for primary separation.  The small footprint technology allows excellent TSS removal (up to 80% for this project depending on influent wastewater quality) combined with the ability to cope with highly fluctuating flows in terms of both quality and capacity. The high-quality stainless steel Hydrotech™ Filters combined with innovative robust PE filter panels guarantees an efficient, low maintenance, robust, and flexible primary separation step.
