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. This article appeared in the May/June issue of D&WR magazine.

Experience helps boost production and stability at Ras Abu Jarjur
Improving production with reduced expenditure could be the main targets of any desalination facility around the world. Such feats are being methodically achieved at Ras Abu Jarjur reverse-osmosis (RO) plant in Bahrain as a result of a series of improvements. Of the many available desalination techniques, RO was seen from the earliest days as a reliable and cost-effective technology and was therefore employed at Ras Abu Jarjur. From the huge quantity of groundwater (40 million m /year) extracted from borewells, potable water totalling 29 million m /year is produced. The other 30% of water is being rejected to the Arabian Gulf, which has a similar salinity level and higher temperatures. Trials are being carried out to extend the brine staging by one more stage from two to three for the ninth and tenth trains and from three to four for the first to eighth trains, as the reject water from the trains is already filtered, acidified, dosed with antiscalant and most importantly possessing the required pressure energy (minimum of 38 bar) to be used. This strategy would increase the overall water recovery by another 4.5%. By closely following the guidelines of the scaling indices, solubility product limits of potential scale-forming constituents in the water and various performance-monitoring tools, it would be possible to recover another 2% of the water. The full article first appeared in the November/December 2008 issue of D&WR magazine. The paper on which it was based was awarded the prize for Best Oral Presentation at the International Desalination Association World Congress in Maspalomas in 2007.
