• New device could help stop one of the world's deadliest killers

    A new portable and low cost water sanitation device could help save millions of lives each year; water borne diseases contracted from contaminated water are one of the world’s leading causes of death; each year nearly two million people die, primarily young children, from preventable diseases like diarrhea, cholera, and typhoid from drinking unsafe water; it is estimated that roughly 1.1 billion people lack access to clean water, but all that could potentially change thanks to Torben Frandsen’s LifeStraw; LifeStraw is a 10 inch long straw that is capable of generating 185 gallons of clean water, requires no electricity, and can be cheaply manufactured

  • Keeping water clean

    Cardiff University researchers create a real-time broadband monitor to detect and warn of impurities in water supplies; the new monitor works by using bioluminescence to detect the presence of potentially toxic substances of chemical or biological origin and immediately warn of suspicious change

  • University of Oklahoma student offers solutions Ethiopia's water problems

    In Ethiopia’s Rift Valley, the high levels of fluoride in the drinking water result in dental and skeletal disease; left untreated, fluorosis causes darkening of the teeth and bone deformities; a University of Oklahoma student has been investigating inexpensive, sustainable and locally available solutions, such as adsorption — a useful technology for fluoride removal from drinking water because it does not require energy input outside of gravity and, depending on the material used, can be very effective at removing fluoride to meet the World Health Organization standard

  • Engineering students win wastewater treatment competition

    In a surprise win, Humboldt State University (HSU) students recently bested engineering students at top ranked California universities to gain first place at the annual American Society of Civil Engineers Mid-Pacific Water Treatment Competition; this year teams were asked to build a system that would treat contaminated water that was heading toward a sensitive wetland ecosystem after an earthen levy around a biosolids compost facility had been breached; the teams were challenged to either design a containment system for the water or a treatment system; the HSU team won the competition beating U.C. Berkeley by more than thirty points

  • New technology quickly detects bioattacks on water supply systems

    If pathogens enter into a city water supply network, many people may fall ill quickly; to protect against this biological threat, researchers have developed a detection system, partly based on nanotechnology, that can warn authorities in time

  • Portable technology provides drinking water, power to villages, military

    Researchers have developed an aluminum alloy that could be used in a new type of mobile technology to convert non-potable water into drinking water while also extracting hydrogen to generate electricity; such a technology might be used to provide power and drinking water to villages and also for military operations

  • West Texas towns face impending water shortage

    West Texas is facing a dire drought that has local officials scrambling to find additional sources of water for thirsty residents; since last October, West Texas has only seen about one-tenth of an inch of rain, and now two of the three reservoirs that cities in the Permian Basin depend upon are nearly empty; the third reservoir is 30 percent below capacity; without significant rain soon, all three reservoirs will be dry by January 2013; residents have been restricted to only three days of outdoor watering; the region faces limited options for additional sources of water and plans will be expensive to implement

  • U.K. struggles to reduce water usage as supplies dwindle

    An uncharacteristically warm and dry spring in the United Kingdom has forced water companies to begin conserving water, but a recent survey indicates that the method currently employed is widely unpopular and grossly affects low income families; some reservoirs are 20 percent below normal levels and eleven rivers are at their lowest in twenty years; in 1989 the British government mandated that all new homes have water meters installed and introduced a usage plan which charges households based on the amount of water they consume; the plan has proven effective in reducing water usage, but costs have increased by more than 50 percent

  • Beverage industry seeks to curb water usage

    The beverage industry is actively working with researchers to conserve water as it requires vast amounts of water in its production processes; as much as 98 percent of the industry’s water usage comes from growing the ingredients used to make drinks; it is projected that by 2030 water demand will exceed supplies by 40 percent; analysts predict that water shortages will disrupt production and in times of scarcity can damage a company’s reputation; Coke has come under fire in India where residents blame the company for severe water shortages and improperly disposing of contaminated sludge; some companies are leading the charge and working with local farmers to help reduce water consumption and bolster local water supplies

  • Computerized irrigation system saves money

    The University of Michigan is using a computerized irrigation system for its campus landscaping; the system uses information from a campus weather station that monitors wind speed, rain, temperature, and humidity to adjust irrigation schedules; the system allowed the school to reduce the amount of water used on irrigation by 22 million gallons of water on landscape irrigation each year — or 68 percent relative to the amount of water used before the system was installed — saving an estimated $141,000 a year

  • Algae could replace 17% of U.S. oil imports

    Environmental and economic security concerns have triggered interest in using algae-derived oils as an alternative to fossil fuels; growing algae, however — or any other biofuel source — can require a lot of water; researchers at the Pacific Northwest National Laboratory the far less water is required if the algae is grown in those regions in the United States that have the sunniest and most humid climates: the Gulf Coast, the Southeastern Seaboard, and the Great Lakes; water-wise algae farming could help meet congressionally mandated renewable fuel targets by replacing 17 percent of the U.S. imported oil for transportation

  • Interest in water technology and business grows

    Some 3,000 foreign visitors and more than 25,000 local participants are expected to attend the November 2011 WATEC, one of the world’s premier water technology events; the emphasis of this year’s conference and exhibition, the be held in Israel 15-17 November, will be on showing how water technology translates into successful projects and enterprises — both for the developed world and those at risk of severe water insecurity; there are about 400 water technology companies in Israel; 200 of them are already exporting their technologies to other countries — exports estimated to be between $2.5 billion and $3.5 billion in 2010

  • New material cleans water of radioactive contamination

    NC State researchers develops material to remove radioactive contaminants from drinking water; the material is a combination of forest byproducts and crustacean shells; the new material not only absorbs water, but can actually extract contaminates, such as radioactive iodide, from the water itself; this material, which forms a solid foam, has applications beyond radioactive materials

  • Keeping water pure with detection nanosensors

    Seven European countries, containing 35 percent of the European population, face a risk of water shortfall; University College Cork will coordinate a 3 million Euro EU project for the development of novel smart sensing materials for applications in water purification technology and clinical diagnostics

  • Wastewater-treatment system to produce electricity

    Scientists will bio-engineer bacteria to break down large amounts of solid waste using anaerobic digestion (without oxygen) in a reactor based on existing technology used by distilleries and pharmaceutical companies; they hope to be able to capture the gas from the process to generate electricity. Because the system would not produce other waste products, they also hope it could improve wastewater treatment in the developed world
