Construction completed on Australia's largest recycled water project
Wastewater reuse is a hot topic in Australia, with the "toilet-to-tap" label being trotted out on many occasions. In the state of Queensland, it has a lot more relevance because, as well as a brand new desalination plant at Gold Coast, the state now has a giant new municipal water reuse scheme. This article discusses completion of the Western Corridor Recycled Water Project, the southern hemisphere's largest recycled water project, and provides a technical overview of the international award-winning Bundamba Advanced Water Treatment Plant. Producing up to 232,000 m /d of water, the WCRWP is the largest in the southern hemisphere and the third largest in the world. It provides purified recycled water, a climate- and rainfall-resilient source of pure water, to three power stations located in South East Queensland. In the future, the project will supply water to industry and potentially agricultural users, and, should the region's drinking water supplies fall below 40%, the Wivenhoe Dam. The project includes a network of more than 200 km of large-diameter underground pipes, three advanced water treatment plants, nine storage tanks and 12 pumping stations. It also provides significant environmental benefits by removing up to 50% of nutrients that would previously have been released to waterways feeding environmentally sensitive Moreton Bay.

The coming of membrane distillation technology
Membrane distillation (MD) is a unit operation that uses hydrophobic membranes as a barrier for contaminated water from which mass transport of vapor is driven by differences in vapor pressure. MD does not require a mechanical pressure pump, and temperature levels are such that low-grade heat sources may be used to supply the required energy for the process. It is therefore ideal for treatment of industrial effluents and for desalination in co-generation with thermal solar power plants. This article assesses membrane distillation, a technology that the author believes is becoming increasingly relevant, particularly for use with renewable energies and in less developed countries. The recent promotion of the Desertec energy creation project in the Sahara is just one opportunity he sees for the technology.
UF Pretreatment For Cold Seawater RO
The main obstacle to the use of UF membranes for SWRO pretreatment has always been the high operating cost.

This article shows how the project results can be translated into a technical and commercial evaluation of the best pretreatment option for the desalination of water from low temperature water sources. The technical design details are described for the Evides demonstration plant in the Netherlands, fed from the river delta formed by the Meuse, the Scheldt and the Rhine rivers in southwest Netherlands. It also explains the decision-making process for selection from pretreatment options for the Thames Gateway SWRO project, a plant that is fed by water strongly influenced by tidal effects.
