  • 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 ...

  • Immersed Membrane Technology for Advanced Wastewater Treatment & Water Reuse

    A significant segment of the North American population is unserviced by municipal wastewater systems and, with the seemingly, unending growth of residential communities, commercial complexes, industrial parks and support infrastructure, this situation is unlikely to change in the foreseeable future. Traditionally serviced by on-site wastewater treatment units, and often relying on groundwater ...


  • Converting rain into drinking water: quality issues and technological advances

    With growing pressures on water supplies worldwide, rainwater harvesting is increasingly seen as a viable option to provide drinking water to an ever expanding population, particularly in developing countries. However, rooftop runoff is not without quality issues. Microbiological and chemical contamination have been detected in several studies, well above local and international guidelines, ...

  • 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 ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review

    Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...

  • Hydrogen sulfide removal from industrial gases using advanced, modified claus technology

    A number of commercial processes are available for removing hydrogen sulfide (H2S) from natural gas, tail gas from the Claus Process (containing un-reactive sulfur compounds, particularly CS2 and COS), coke-oven gas, pyrolysis gas and solution tail gas from heavy oil production. These processes are often limited by economics and technology. In the economic range from about 0.1 to 15 tons sulfur ...

  • 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 ...
