  • 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 ...

  • Energy recovery from biogas purification

    Energy recovery from biogas is becoming more common, but the processes are hampered with the presence of hydrogen sulfide (H2S). Biogas is a mixture of methane and carbon dioxide (CO2) and is often contaminated with toxic quantities of H2S. Sources of biogas are: municipal landfills that produce landfill gas (LFG), wastewater treatment plants, industrial plants, and large scale livestock farms. ...

  • 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 ...

  • Impact of the climate conditions on the purification power of Beni Messous natural lagoon

    In this study, we will establish the correlations between the climate variables and the outputs of the pollution elimination in the natural lagoon of Beni Messous, using multiple regression method. We have chosen the ascending method 'FORWARD' for the selection of these variables in each regression. After the analysis, it has been noticed that the elimination output of the biochemical oxygen ...

  • 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 ...

  • Case study - Purification of biogas in EDAR Mapocho

    BIOCONSERVACION: Integral solution for biogas purification in WWTPs Biogas is mainly composed by methane and carbon dioxide as a result of organic matter fermentation in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of biogas depends entirely on the nature of the waste processed and the conditions under which takes place the anaerobic digestion. ...

  • Challenges of Fuel Gas Purification for Cogeneration Under Stringent Regulatory Requirements

    ABSRTRACTInland Empire Utilities Agency (IEUA), a municipal water district based in Chino, CA is currently executing a cogeneration power project, titled Renewable Energy Efficiency Project (REEP) at the Regional Plant No.5 (RP-5), which showcases a variety of innovative technologies for the power production. The project involved many innovative technologies, most of which are still in the ...

  • Evaluation of the quality and self purification potential of tajan river using qual2e model

    Industrial development accompanied by population and consumption growth has imposed heavy pollution loads to natural resources. Regarding finite origin of such resources, maintenance and monitoring of current ones must be thoroughly considered. Water is among the most significant resources that must be preserved. This fact is more highlighted when we consider that Iran with current population ...

  • 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 ...

  • Evaluation of a silver-ion based purification system for rainwater harvesting at a small-scale community level

    Silver has been known for centuries to be a powerful disinfectant, with no known harmful effects to humans if applied in adequate doses. Although its use was partially discontinued with the advent of chlorination and modern antibiotics, the discovery of bacterial resistance and disinfection by-products has enabled its re-emergence as a viable water purification option. On the other hand, ...

  • 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 ...
