  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Water purification: a sustainable technology for rural development

    This study deals with the preliminary investigation on combined treatment with the coagulative ability of Moringa oleifera seeds to reduce turbidity and to determine the effectiveness of solar disinfection for the inactivation of Escherichia coli (E. coli) and coliforms on various turbid waters. Turbid water samples showed drastic reduction in microbial load and turbidity at time interval of 60 ...

  • The effect of immobilized catalyst structure on the degradation of chemical and biological contaminants in simulated solar photocatalytic water purification

    The performance of different configurations of titanium dioxide-coated foam supports as photocatalysts in an enhanced solar disinfection system for drinking water treatment was evaluated, using the reduction of methylene blue, 1-4-dioxane, and Escherichia coli as performance indicators. Reactors with immobilized catalysts were able to match or surpass the performance of a suspension ...

  • Solar disinfection of natural waters with modified solar concentrators

    Solar water disinfection is a proven method for household purification of drinking water. Compound parabolic collectors (CPCs) have been used to enhance the inactivation rate of microorganisms. In the present study, a modified CPC with a higher concentration ratio of 1.1 was employed to further speed up the process. A large number of tests were conducted with water samples collected from ...

  • In the World: Small Mexican village produces clean water with solar-powered system

    MIT-developed system runs autonomously, producing 1,000 liters per day. In a small village deep in the jungles of the Yucatan Peninsula — a day’s drive from any source of clean, drinkable water — researchers from MIT are testing a system that purifies water with the help of the sun. The relatively inexpensive system consists of several modest photovoltaic panels, a large ...

  • Solare Klärschlammtrocknung in der Praxis - Erfahrungen auf der Kläranlage Glarnerland

    The water purification plant Glarnerland produces yearly roughly 4 000 tons of digested sludge (DM 25 %). Through drying, partially using in agriculture and the rest burning in the county's waste incineration plant the final disposal of the sludge is solved. The new solar sludge drying plant uses solar energy and waste heat taken from the electrothermal power station. In the new solar drying ...

  • The effect of pyrite on Escherichia coli in water: proof-of-concept for the elimination of waterborne bacteria by reactive minerals

    We present proof-of-concept results for the elimination of waterborne bacteria by reactive minerals. We exposed Escherichia coli MG1655 suspended in water to the reactive mineral pyrite (FeS2) at room temperature and ambient light. This slurry eliminates 99.9% of bacteria in fewer than 4 hours. We also exposed Escherichia coli to pyrite leachate ...

  • A short overview of the state of the art and perspectives on the main basic factors hindering the development of photocatalytic treatment of water

    This brief overview focuses on three of the main basic phenomena limiting the applications of photocatalysis using semiconductors for the treatment of water, so that this technology has really not gone beyond the demonstration stage aside from niche applications. These phenomena are: the recombination of photogenerated charges; the adsorption of trace organic pollutants; the spectral range of ...

  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

  • 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, ...

  • Green Urban Infrastructure: Assessing Potential Ecosystem Services in Urban Cities

    Cities all over the world are currently experiencing climate change caused by rapidly increasing atmospheric greenhouse gases (GHGs). Fortunately, cities may mitigate GHG concentrations by incorporating vegetation into green urban infrastructure (GUI) to develop parks, green roofs, waterways, and other structures. For example, plants sequester carbon (C) by removing atmospheric ...
