Looking back on two years of change in desalination
At the start of Lisa Henthorne’s presidency, at the Maspolomas Congress in 2007, the board of the International Desalination Association initiated a five-year Strategic Plan. Already parts of the plan, such as better public relations, membership growth, including a Young Leaders program, and the new IDA Journal are all up and running. D&WR asks Henthorne…

Ozone improves ceramic membrane use for wastewater reclamation
Ceramic membranes have been used in the industrial production of beer, wine and cheese. One of the reasons for this use is the narrow pore size distribution, where careful separation of different size compounds can be achieved. Outside of Japan, the use of ceramic membranes has been almost non-existent for municipal drinking-water systems. The slow…

Combining Forward Osmosis with Reverse Osmosis
A combination of forward osmosis with reverse osmosis could facilitate the treatment of some high fouling wastewaters. The system uses brine to draw water from the wastewater without high pressure or turbulence. Key element is the membrane’s ability to allow rapid passage of water without much internal concentration polarization. The diluted draw solution can then…

Large Diameter RO Desalination Elements
In recent years, increasing the diameter of spiral elements has been studied as a method of lowering the cost of membrane treatment. It has been shown that the installed cost of a reverse osmosis (RO) plant can be reduced by up to 27% using larger diameter elements.Large diameter elements provide savings in footprint and building…

Industry Interview – Dan McCarthy – From research to commissioning: how B&V has it all covered
With another prestigious water project opened in May in the shape of the 228,000 m /d Sembcorp NEWater Plant in Singapore, the list of references for major desalination and water reuse projects involving global engineers Black & Veatch in various capacities grows ever more quickly. John Gould, chairman of Faversham House Group and the publisher…

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…

Resort uses desalination in innovative reuse project
The Cache Creek state-of-the-art water reuse project in the USA is very interesting for its use of the Vibratory Shear Enhanced Process (VSEP) for brine volume reduction. However the use of Electrodialysis Reversal (EDR) desalination prior to this process is also of interest, and the project s award from the WateReuse Association (2009 Project of…

Reclaiming the grass at Pebble Beach golf course
Tertiary treatment of wastewater has had a technology upgrade to improve play at Pebble Beach golf course, which recently hosted the US Open Championship. The problem was high sodium and total dissolved solids concentrations, and difficulties with reusing wastewater during low flows. Microfiltration followed by RO was selected to meet the water quality criteria. The…

Welcome to Water Planet
It’s 9am in California and Eric Hoek is speaking from his car. Fresh from dropping his two pre-schoolers off for the day, the former UCLA engineering professor turned CEO is ready to concentrate on his other ‘babies’ – the two divisions of Water Planet, the water tech company he started with private investment following his…

Boost for San Angelo water reuse plan
Plans for a water reuse project in San Angelo, Texas, received a boost this week, with local council staff given the green light to take the next step in seeking funding for the project.
