  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Electrochlorination system: a unique method of prevention of biofouling in seawater desalination

    Desalination plants require huge volumes of seawater for the generation of fresh water. Seawater contains large amounts of microbiological fluids which, when passed through the piping system, form biofouling in the inner surface of the pipeline, which results in the reduction of the flow rate of water without proper chemical treatment. Chlorine is the most commonly used disinfectant for water ...

  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • The Alamitos Barrier Recycled Water Project

    Groundwater pumping in the Los Alamitos, California area over the last century has caused groundwater levels to drop, allowing seawater to intrude into the local groundwater aquifer. To prevent additional infiltration by seawater, a coastline barrier of wells injecting fresh water has been in place since 1965. Until recently, imported potable drinking water was injected into the aquifer. However, ...

  • Case study - Interest grows in OPEX saving UV water treatment technology used for enhanced oil recovery

  • Jersey specifies Trojan - again

    Jersey Island, British Isles, is a popular tourist destination for Europeans. It’s the largest of a series of small, independent islands in the English Channel near the coast of Normandy. In 1992, Trojan’s U.K.subsidiary, Sunwater Limited, provided a state-of-the-art water disinfection system to upgrade Jersey’s then thirty-three year old main sewage treatment plant at Bellozanne, near St ...

  • Recycled Water saves California Farms

    After studies show no viable microorganisms in tertiary treated wastewater, growers in Salinas Valley now get two-thirds of their agricultural water needs from recycled sources. RECYCLED water is saving the farm for approximately 75 growers in the Salinas Valley along California’s Central Coast. Because their wells were becoming contaminated with seawater, these growers began irrigating their ...

  • Advanced Water Treatment Technologies May Bring Purified Water to San Diego

    'In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets,' reported the San Diego Union-Tribune recently. A plan to mix 'repurified water' with the City's raw drinking water reservoir could become a reality, thanks to the wonders of water treatment technology. Such a possibility elicits various reactions including disgust, marvel and fear. ...

  • Can saltwater quench our growing thirst?

    An increasingly water-stressed world takes a new look at desalination. It seems simple enough: Take the salt out of water so it’s drinkable. But it’s far more complex than it appears at first glance. It’s also increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
