  • Artificial water systems create unintended consequences

    Amidst the semi-arid stretches of Phoenix, a visitor might blink twice at the sight of a sailboat cutting across the horizon. Tempe Town Lake, on the northern edge of Arizona State University, is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water delivery, recreational opportunities and aesthetics, and altering perception of water availability and ...

  • Top Cooling Tower Filtration Systems Reduce Water Consumption and Maintenance

    Cooling tower efficiency can be easily maintained by installing the right filtration system. Keeping process-water clean is essential to maximising the efficiency and performance of an industrial cooling system.  Dirty process water clogs cooling tower and other heat exchange ...

  • Water footprint of energy

    As Japan’s nuclear power plant emergency has highlighted, water is needed in copious quantities to generate energy. To mark World Water Day, Sandra Postel (National Geographic) considers the huge water footprint of energy generation. According to USGS, thermal power plants (fuelled by coal, oil, natural gas or uranium) account for 49% of water withdrawn. We don’t think much about ...

  • Leak detection of oil in cooling water

    Gas compressor plants for one of the USA’s largest suppliers of industrial, medical and specialty gases, use oil / water heat exchangers to cool compressor lubricating oil.  Oil is on one side of a heat exchanger and cooling water on the other side.  Some of the plants have open loop once through cooling systems, with discharge back to a river or lake.  If a heat exchanger leaks ...

  • Ocean salinities show an intensified water cycle

    The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

  • Keeping an eye on water use… from space!

    As food shortage weighs heavily on the minds of many, several countries recognise the key role irrigation can play in this issue. A team of EU-funded researchers teamed up to assess how the latest satellite imagery can be applied not only to make water use more efficient, but also to boost farming output in the process. Researchers from Europe, North Africa and North America are using the ...

  • Treatment of Different Wastes by Supercritical Water Oxidation

    Abstract If left to conventional treatment processes, the destruction of toxic organic wastewaters and associated sludge volume reduction clearly becomes an overwhelming problem. Two options, incineration and supercritical water oxidation (SCWO), exist for the complete destruction of toxic wastewaters and organic sludges. Incineration has associated problems such as very high cost and ...

  • Fracking Boom Threatens US Water Supplies

    Since the onset of the fracking boom almost a decade ago, every state in the US has been examining its geological resources in the hope of finding oil or gas it can access through this extraction method. Almost half the states are now producing at least some shale gas, with a few – Texas, Pennsylvania, California, Colorado, North Dakota – sitting on massive ...

  • On-site water treatment service from Tangent Environmental Technologies cuts costs

    After more than two decades in the global oil patch, Stuart Snydmiller thinks the future for his start-up firm is in water, not petroleum. Or at least waste water.Tangent Environmental Technologies, owned with brother Jason and others, has taken existing technologies and put them together into a package that offers huge savings for drilling firms and any industrial operation that needs to ...

  • Report examines impact of climate change on drinking water supplies

    Warming of the earth's atmosphere will continue to put mounting pressure on America's drinking water sources, leading to diminishing supplies in some regions and flooding in others, according to an analysis released today by the Association of Metropolitan Water Agencies (AMWA), a nonprofit organization of the largest publicly owned drinking water systems in the United States. AMWA's report, ...

  • H2O GmbH is a new partner of the Blue Competence sustainability initiative

    Sustainability is the hot topic of our time. In a world of dwindling natural resources, taking environmental responsibility is absolutely essential. That’s why the German Engineering Association (VDMA) launched the Blue Competence sustainability initiative. Since its launch in early 2011, around 400 partners from the European mechanical engineering industry have ...

  • Innovative solutions to managing wastewater in the Netherlands

    More people will soon live in cities than in rural areas, and 18 of the 23 mega cities worldwide will be in a river delta or on the coast, according to the World Business Council for Sustainable Development. As a result, water safety risks will increase, pressure on water systems will grow, and the amount of sewage water will swell. Dow Chemical’s Terneuzen manufacturing site in the ...

  • Dirty air brings rain -- then again, maybe not

    An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true, depending on local environmental conditions. The determination of this issue is one with significant ...

  • ERG completes acid fume treatment project in Central Asia

    Horsham, UK based ERG (Air Pollution Control) Ltd has completed a £300k project to supply an acid fume scrubber to Kazakhstan. The client is the petrochemical giant, Tengizchevroil, which is a joint venture between Chrevron, Exxon Mobil, and local Kazakh operators KazMunaiGas and LukArco. The client needed the scrubber to treat hydrochloric acid (HCl) fumes which are given off from a 50m3 ...

  • Reducing Environmental Effects of Cooling Towers

    The implementation of strict environmental regulations worldwide calls for mine operators and managers to take immediate action to reduce the environmental effects of their operations. Cooling towers, a crucial component of the mining process, have naturally come under scrutiny in recent years and it is therefore vital that ...

  • Greening the Ice - FortisBC to reduce CO2 emissions from ice rinks

    FortisBC commits to reduce up to 500t of CO2 emissions from ice rinks through new pilot program. With a recently announced FortisBC pilot program partnered with REALice technology, 10 BC participating ice rinks will receive a rebate that will completely cover the installed cost of a REALice system up to $29,000. This means that each ice arena could reduce carbon emissions by 50 tons per ...
