Hydroflux Epco Plays a Key Role in Subiaco Wastewater Treatment Plant Upgrade

June 8, 2018

Hydroflux’s subsidiary, Hydroflux Epco has played a vital part in the recent upgrade of the Subiaco wastewater treatment plant, the third largest of its kind in Western Australia.

HUBER RoSF4 grit washing

It is part of an upgrade project that will boost the plant’s capacity to up to 67 million litres a day.

The increase in capacity has been driven by the need for the plant to treat additional wastewater as the populations of Perth, Scarborough and Fremantle continue to grow.

The upgrade included the replacement of secondary treatment components and modifications to the plant’s power supply as well as the work done by Hydroflux Epco on the plant’s inlet works system.

Part of the upgrade of the inlet works included the installation of a new grit washing and dewatering facility – with Hydroflux Epco contracted to supply three HUBER RoSF4 grit washers.

The key to the HUBER RoSF4 grit washing technology is the final dryness that the unit delivers. The associated volume reduction and hence, transport costs, is significantly reduced. This technology has been operating in Australian sewage treatment plants since 2003 and in Western Australia since 2008.

This installation brings to more than 2,000 the total number of units that have been delivered to sewage treatment plants around the world.

HUBER invented the concept of the fluid bed grit washer in the early 1990s. All wetted parts are manufactured from 316L stainless steel and pickled in an acid bath for 14 hours. There are four sizes of HUBER RoSF4 grit washers to suit treatment plants of any capacity.

“Whilst many competitors have copied the design, none can match the performance and reliability due to HUBER’s extensive technical and design knowledge gained through co-operation with leading German universities and hundreds of site references,” says John Koumoukelis, Hydroflux’s Director of Global Business Development and a Director of Hydroflux Epco.
