  • Advanced technology for water purification by heterogeneous photocatalysis

    The TiO2 photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) was examined using a prototype photoreactor fabricated by Nulite. The degradation of both pollutants proved very efficient as in 12 min it was possible to bring the concentration of 2,4-DCP from 10 to 0.5 p.p.m. and in a separate experiment the concentration of PCP from 100 to 0.5 p.p.b. The effect of ...

  • 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 ...

  • R&D areas for next-generation desalination and water purification technologies

    By 2020, desalination and water purification technologies are expected to contribute significantly to ensure a safe, sustainable, affordable and adequate water supply in India. The cost of producing water from the current-generation desalination technologies has declined over time at a rate of only approximately 4% per year. Hence the need to accelerate our Research and Development (R&D) ...

  • Affinity adsorption for the removal of organic micropollutants in drinking water sources; proof of principle

    Sources for drinking water (DW) production contain increasing concentrations of organic micropollutants, such as pesticides and pharmaceuticals. Traditional purification processes are not suitable for their removal or conversion, but even sophisticated technologies, like advanced oxidation processes and membrane filtration, are not able to efficiently remove all compounds from DW. For ...

  • Purification Of Industrial Gases: Chemical scrubber vs Physical Adsorption

    Gas purification using a chemical scrubber is a technology that has been applied successfully for decades for the purposes of eliminating contaminants in a gas flow. However, although it is a technique that is easy to design and quite flexible, it entails certain disadvantages and/or risks. In recent years there has been considerable interest in developing alternative ...

  • 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 ...
