96 AUGUST 2011 water water business water business NANOH2O AWARDED NSF STANDARD 61 CERTIFICATION NanoH2O Inc, manufacturer of the next generation of reverse osmosis (RO) membrane technology, is proud to announce that its flagship product has received NSF Standard 61 Certification. This Certification attests to the safety and viability of QuantumFlux membrane modules when used in the production of drinking water. NanoH2O utilises advanced nanotechnology to increase membrane permeability by 50--100% over conventional membranes, while matching best-in-class salt rejection. Greater permeability translates to increased membrane productivity, thus decreasing energy consumption which is the major cost of desalination. QuantumFlux membrane modules are produced at NanoH2O's Los Angeles- based manufacturing facility and are available in an 8-inch (20.32cm) diameter spiral-wound configuration that fits into industry-standard pressure vessels. NSF International is a leading global organisation that provides standards development, product certification, auditing, education and risk management for public health and safety. NSF Standard 61 sets criteria for the testing and evaluation of products that come into contact with drinking water to ensure they do not leach contaminants into the water. These contaminants include those regulated by the United States Environmental Protection Agency (USEPA) and Health Canada, as well as any other non-regulated compounds that may be of concern. "This is a mark of distinction within our industry that validates the safety and viability of our nanocomposite membrane technology in the production of drinking water," said Jeff Green, CEO of NanoH2O. "I am very proud of our world-class product development and manufacturing operations team who worked diligently to ensure our product's compliance to NSF 61 Standards. With our recently announced commercial launch, this achievement is another testament to the global commercial applicability of our technology." Designed to fit into new and existing desalination plants worldwide, NanoH2O's membranes are at the forefront of combating critical water scarcity issues. NanoH2O is the 2010 Wall Street Journal Innovation Award winner in the environment category.

Right now, distribution systems around the world are losing an average of 26% of treated water, which amounts to almost $14 billion in lost revenues. But reducing water loss is not just about increasing revenue. It is also about conserving water and energy, reducing carbon footprints, and supplying clean water to the global population. To successfully address water loss problems, water utilities are challenged to be cost-effective and efficient in implementing long-term programs that consistently reduce both commercial losses (from, for example, theft) and physical losses from leakages. Well- developed information management, water system simulation and optimisation modelling technology, as well as increasingly improved monitoring of systems, are valuable tools that can help engineers effectively execute water loss reduction programs. For example, Bentley's award-winning modelling technology leverages the usage of asset information and enables engineers to quickly construct hydraulic models, simulate leakage with pressure- dependent demand analysis, and identify the likely leakage hotspots during the model calibration process. In addition, Bentley Institute Press, publisher of cutting-edge university textbooks and professional reference works for the architectural, engineering, construction (AEC), geospatial, owner- operator, and educational communities, has announced the release of its newest title, Water Loss Reduction. Written by a prestigious group of water loss experts from around the world, the book addresses the needs of water utility managers, a wide range of engineers (including water resources, hydraulic, and environmental), as well as teachers and students of the water engineering disciplines. It joins the many other widely acclaimed water books in the Bentley Institute Press catalogue, including the Water Resources Modeling collection. What makes Water Loss Reduction stand above other books on the subject is its comprehensive scope, covering in detail everything from the basics of water loss to almost every method of reducing it, including conventional device- based approaches, data management, simulation and optimisation analysis, online monitoring, pressure management, and pipeline condition assessment and renewal planning. In reviewing the book, Kobus van Zyl, professor, University of Cape Town, South Africa, said, "Water Loss Reduction provides an excellent exposition of water loss modelling and management from an engineering perspective. It neatly fills the gap that existed in the literature between the fields of water losses and network WaterGEMS® and SewerGEMS HYDRAULIC ANALYSIS SOFTWARE TO HELP MAKE WATER SYSTEMS MORE EFFICIENT WaterGEMS and SewerGEMS come equipped with everything engineers need in a fexible multi-platform environment, from automated fre fow and water quality simulations, to criticality and energy cost analysis, to automated design, bottleneck detection, and water loss analysis. These applications are part of Bentley’s integrated water solution which addresses the needs of owner-operators and engineers who contribute to the infrastructure lifecycle.
