Possibilities for energy optimisation in design and operation of SWRO plants

Seawater desalination with reverse osmosis (SWRO) has taken a noteworthy upturn during recent years. One of the reasons for the success of the membrane process is its lower energy consumption in comparison with thermal desalination processes. The high-pressure RO desalination stage is undoubtedly the dominating energy consumer of an SWRO plant. Energy consumption of SWRO, despite its energy-recovery aspects, is also influenced by a huge number of additional factors. These are both of an external nature (eg, environmental conditions and stipulations), but are also determined by design and configuration of the plant. On the basis of an SWRO plant model, which covers the different pre-treatment and RO configurations and also the design with energy consumption of potabilisation and additional wastewater treatment and sludge dewatering facilities, the specific energy consumption of an SWRO and its subsystems has been determined in this article. Considering the various aspects to be taken into account for optimization of energy consumption in seawater reverse osmosis plants and the fact that in most cases these measures are offset by increases in capital costs for equipment or possibly also in chemical consumption, optimisation of the energy consumption of SWRO plants during planning and operation is a quite extensive and complicated matter and a demanding engineering task. This article is an expanded and updated version of the article published in the August/September issue of D&WR magazine.

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.
