Doosan Hydro Technology works on the largest recycled water scheme to be constructed in Australia
The Luggage Point Alliance has awarded Doosan Hydro Technology a contract to supply reverse osmosis (RO) skids and membranes to the Luggage Point advanced water treatment plant (AWTP). The AWTP will supply 66 million litters per day of purified recycled water to the Western Corridor Recycled Water (WCRW) project. The Luggage Point AWTP is a major component of the WCRW project—the largest recycled water scheme to be constructed in Australia and currently the largest project of its kind in the southern hemisphere.
The WCRW project will involve building a pipeline from six wastewater treatment plants in Brisbane and Ipswich to three advanced water treatment plants for treatment before being transferred to end users. Stage one consists of sourcing wastewater from the Oxley, Goodna, Bundamba and Wacol treatment plants; in Stage two the Luggage Point and Gibson Island treatment plants will be linked to the pipeline.
The Luggage Point AWTP is a vital part of the WCRW Project. Doosan Hydro Technology’s design and construction will assist the overall WCRWP objectives to significantly reduce pressure on dams and waterways in the region by providing an alternative water supply to industry, power generators and other water users. The AWTP will provide purified recycled water utilizing pretreatment, microfiltration, RO membrane treatment and UV post treatment.
The plant will consist of four trains equipped to operate at an overall recovery of 85% with an energy recovery turbine third stage boost. The system will include four feed water booster pumps and cartridge filters, four RO skids with HP pumps and one CIP system. The facility is planned to operate at a maximum feed water flow of 1,144 cu meters per hour and a permeate flow of 972 cu meters per hour per RO skid.
Dick Dei, Doosan Hydro Technology’s Project Manager, said, “Doosan Hydro Technology is working collaboratively with CH2M HILL to provide an engineered AWTP that meets the client’s specific needs. CH2M HILL was offered pre-engineered packaged systems by our competitors, but chose Doosan Hydro Technology because we were willing to work with them to design a plant specifically for their needs and our modular design allows off site fabrication which minimizes work on site.”
Doosan Hydro Technology will play a key role in helping the Luggage Point Alliance and the Western Corridor Recycled Water Project actively secure a quality water supply that is essential for achieving sustained growth in South East Queensland and will successfully meet the water.
