  • 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 ...

  • Introducing ozone to water purification – Case Study

    Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along ...

  • 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 ...

  • Everything You Need to Know About UV Water Purification

    If you draw water from a well or lake and are concerned about its quality, a UV Water purification system might give you the peace of mind your water is safe to use. Households on municipal water systems are not completely safe either, as water main breaks and broken pipes which can lead to water contamination occur frequently. The ultraviolet water purification process uses ultraviolet light or ...

  • 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 ...

  • Power Plant in Thailand Uses Liqui-Cel® Membrane Contactors to Remove CO2 From Water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which canreduce the performance of the system. ...

  • Ecological and economic aspects of carbon sorbents application in the TPP water flows treatment process

    Substantial economic and ecological effects for thermal power projects (TPPs), can be achieved by improvement of the carbon sorbents (CS) application process providing fine pre-treatment of feed water, return condensates and purification of sewage. CS with inside surface of 106 m²/kg are able to extract contaminants from liquid mediums to any desired degree of water purification both ...
