  • Technico-economic assessment of groundwater treatment by palladium-on-zeolite-catalyst in comparison to GAC fixed bed adsorbers

    A technico-economic comparison between palladium-on-zeolite (Pd/Y), and granular activated carbon (GAC) based methods of groundwater clean-up is presented. The treatment concepts are assessed by means of process-based cost functions that can be applied to a broad range of case-specific conditions. The analysis accounts for variability in cost and performance parameters and reduces the interplay ...

  • Market transformation: can washing machines really help clean up surfing?

    The culture of surfing is awash in environmentalism. It has soul, it's connected to the natural rhythms of the earth, it has icons like Jack Johnson singing about reducing and reusing. Beneath the mythical veneer, however, the business of surfing (worth $7 billion annually) is big business. So it has all the usual problems - and then some - as it looks to live up to its eco-friendly image. Most ...

  • Clean Air Act`s New Source Review Provisions Give Greater Flexibility

    Thousands of U.S. companies who produce emissions could be affected starting this month by new rules under the Clean Air Act's New Source Review (NSR) provisions, published in the Federal Register by the U.S. EPA on Dec. 31, 2002. The article will discuss details of the new NSR rule, and then outline how to take advantage of the new rules. The new provisions particularly concern electric ...

  • Investigation of surface and filtration properties of TiO2 coated ultrafiltration polyacrylonitrile membranes

    In the present work, the surface and filtration properties of TiO2 coated polyacrylonitrile ultrafiltration membranes were investigated. The membranes were coated using the physical deposition method. The appropriate TiO2 coverage proved to be 0.3 mg/cm2, which formed a hydrophilic cake layer on the membrane surface. The cleanability without chemicals and the retention of the ...

  • Catalysis of atomic hydrogen to new hydrides as a new power source

    Having the potential for a clean new energy source, rt-plasmas of certain catalysts (Sr+, Ar+, K) with H formed at extraordinary low field strengths of about 1?2 V/cm. Time-dependent, extraordinarily fast H (25 eV), an excess power of 20 mW ? cm−3, and characteristic K3+ emission confirmed the resonant nonradiative energy transfer of 3 ? 27.2 eV from atomic hydrogen to K as the rt-plasma ...

  • Let’s talk plasma

    Usually when I attend a conference on behalf of Tetronics I am about the average age of the other delegates. Not this time. Suddenly, I am old enough to be the father of most of the other people here, because this is a university-based conference hosted by the University of Liverpool. Yes, this is the snappily-titled International Workshop on Plasmas for Energy and Environmental Applications, or ...
