Drinking Water for Sydney
Sep 16 2008
Sydney`s desalination plant is being designed and built by a joint
venture of John Holland Group, one of Australia`s largest multidiscipline design and construction contractors, and Veolia Water, a
world leader in desalination plant construction and operation.
Following its completion, the desalination plant will supply up to
250,000 cubic metres of fresh drinking water per day. The plant works
according to the physical principle of reverse osmosis (RO). The just
under 70 bar pressure required to separate salt and water is provided,
among others, by 13 high-pressure HGM-RO 8/3 pumps, each with a pump input power of approximately 2 000 kW. The outstanding feature of the radially split units offering a capacity of more than 1 000mÂ³/h per hour is their high efficiency. They therefore consume considerably less energy than the conventional axially split pump designs. This type series is also particularly easy to service and has proved successful in numerous pumping plants all over the world.
The order also includes the supply of 33 other high-pressure pumps
and jockey pumps from various pump ranges. Delivery of the highgrade
stainless steel pumps is scheduled to start in September of this
year and will be complete in March 2009. One of the reasons the
German pump manufacturer was awarded the contract was their
extensive service network in Australia.
The new seawater desalination plant in Kurnell, a suburb of Sydney, is
intended to secure the water supply of the city`s rapidly growing
population in the years to come. If necessary, the installation`s capacity can be increased to 500,000 cubic metres per day.
