Joint venture iN2ovate, with partners Aquatec Maxcon, John Holland and GHD, has been selected by Melbourne Water to participate in the trial phase of upgrading the Western Treatment Plant and study the potential of the Nereda waste water treatment technology of Royal HaskoningDHV.
The objective of this project is to select preferred treatment technologies for a new secondary treatment plant with a nominal treatment capacity of 160 million litres a day.

Trial phase to optimise designs
Melbourne Water set up a three-stage program for the upgrade of its wwtp to provide innovative, cost-effective and integrated solutions to managing environmental compliance (biodiversity and marine discharge) and increased sewage loads and recycled water demand into the future.
The three Australian-based partners in iN2ovate will have opportunity to optimise designs for a Nereda plant, and for Melbourne Water to refine its requirements and gain a better understanding of viable solutions. This includes pilot plant trials and onsite testing.
Melbourne Water selected three joint ventures for its trial phase. The other two are Organic Water and Thiess-UGL-Jacobs.
Selection of best technology
Project manager Guy Fazzino said Melbourne Water was excited by the potential for the project to further demonstrate the organisation’s commitment to innovation and sustainability in the water industry.
"We have structured this project so that we can confidently invest in the best technology and knowledge to build a cost efficient asset which will ensure we continue to deliver great value service to our customers", Said Mr Fazzino
The next phase of the project, will involve the design and construction of a full scale secondary sewage treatment plant which was developed from the preferred treatment concept identified from the last phase.

Nereda is a cost-effective biological wastewater treatment technology based on a unique aerobic granular biomass, which are purifying bacteria that create compact granules with superb settling properties.
It stands out for its high treatment capability in combination with significantly lower investment and operational costs, a very small footprint (up to a factor 4 smaller) and high energy savings, up to 50%.
There are plants in operation and under construction in the Netherlands, Portugal, Poland, South Africa, Brazil, the UK, Ireland, Switzerland and the recently awarded at Kingaroy WWTP, in Australia.
The Nereda technology is developed by Royal HaskoningDHV in cooperation with Delft University of Technology, the Foundation for Applied Water Research STOWA and Dutch water boards.
