The organisers of this year's Winter Olympic Games demanded as much from its water infrastructure as did its competitors. A reliable, environmentally friendly water solution was required, which would remain viable long after the games had ended. This goal was achieved with the installation of a range of energy and space saving solutions. 06 August 2010
After six years of well below average rainfall, South East Queensland was in the grip of the worst drought in the state’s recorded history. A rapidly expanding population placed an unprecedented demand on the dwindling water supplies. In response, the Western Corridor Recycled Water Project began diversifying the region’s water sources by providing a new source of pure water to power stations. 19 July 2010
An gold mining operation required a wastewater treatment system to enable water recycling on-site. The environmental initiative called for a solution which would achieve optimum performance while requiring little maintenance. The introduction of a Fixed Activated Sludge Treatment proved a successful addition. 20 May 2010
Population growth and improving standards of living, coupled with dramatically increased urbanization, are placing increased pressures on available water resources, necessitating new approaches to urban water management. 28 April 2010
A Netherlands-based chemicals manufacturer has installed a water treatment system combining ultrasonic microbiological control and corrosion inhibitors, and has reaped environmental and economic benefits. 11 February 2010
Three of Ireland’s largest stadiums have recently been overhauled and Tsurumi Pumps was chosen for pitch dewatering and sewage handling. The systems includes a sophisticated and environmental-friendly irrigation system. Further, a high-tech approach provides far more accurate control and more eÿcient use of the pumps. 05 February 2010
Wastewater reuse is becoming increasingly important in many parts of the world. Anthony Bennett describes the role of regulators in this area and highlights how advances in filtration technology are driving the market. 17 November 2009
Martin Hunt of Festo describes how companies can benefit from using the correct choice of valve technology. For one company, adopting the recommendation to change to pneumatic pinch valves instead of butterfly valves provided significant long-term cost savings and performance benefits. 09 October 2009
Energy costs are soaring and water supplies are depleting. Instead of paying for the disposal of process water, companies could be reusing it and reaping the benefits. By installing additional filter technology, companies have the potential to see a return on their money within six months. 09 October 2009
Improvements in RO membrane elements have provided a threefold increase in the amount of treated water per element while reducing energy costs in desalination and water purification projects around the world. Currently, desalination plants with Dow Water & Process Solutions technology enable more than 218 million gallons of freshwater to be produced every day. 08 October 2009
As we are all aware, water is becoming a scarce and expensive commodity. The beverage and food industries, looking to increase the recycling of their process water to keep costs low, are turning towards membrane bioreactors for water treatment. Alfa Laval's Detlef Ahrens explains how it works. 25 March 2009
Working with Water spoke with Ian Barbour, General Manager of Dow Water Solutions, about the important issues of water provision and quality in the world today – from the cost of providing clean water in India, to desalination in Australia. 25 March 2009
The challenges of changing regulations and standards can mean difficult situations for water companies. As new discharge limits and controls come into force, traditional treatments can become redundant. Severn Trent Services explain how they have been using filtration technology to meet the challenges. 25 March 2009
The Harnaschpolder wastewater treatment plant, based in the Netherlands and run by Veolia, is a great example of a modern filtration system with a look to the future. Filtration+Separation visited the plant to find out how it operates. 18 March 2009
Cost and consent levels have made it all the more important to control phosphate levels in wastewater. Partech describes an alternative to the traditional methods of iron salt dosing which can improve dosing accuracy and efficiency. 04 March 2009
In wastewater plants, the 8-inch diameter x 40-inch long RO element has been the standard in RO systems for many years, but is clearly not the optimum for today’s large systems. Peter Moss, Robert Skelton and Michael Tylla of Koch Membrane Systems examine the issues related to the use of large elements, and show how these challenges have been addressed. 04 March 2009
How does the hydrological cycle – in all its varying scales – work? What are the threats to water budgets and water quality? In this article, we take a look at the impact of human use and how we can interact with the water cycle in a long term and sustainable way. 04 March 2009
The Australian town of Goulburn’s timely water initiative presents a model for the future as cities learn to live with drought and other water challenges. Was an ultraviolet disinfection scheme for irrigation part of the answer? 04 March 2009
