  • What is the best way to do trace metal sampling?

    All samplers contaminate or distort in some way. • Plastics may leach metals from ultraviolet inhibitors, metal-organic plasticizers, (rarely) metal catalysts. • Teflon has a rough porous surface into which ions, fine charged particles, and very fine particles may become attached. Errors may occur in your first sample due to these trapped trace elements. • ...

  • The Right Mix for Clean Air

    Reducing air pollution is an increasingly important topic all around the world. Many governments—also in developing countries—set new limits for emissions such as nitrogen oxides in flue gas. Sulzer offers advanced mixing technology for flue gas cleaning. The installation in a large power plant shows that these high-performance mixers can cope with the most difficult requirements. ...

  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. ...

  • Synthesis and performance of antifouling and self-cleaning polyethersulfone/graphene oxide composite membrane functionalized with photoactive semiconductor catalyst

    This study was performed to synthesize membranes of polyethersulfone (PES) blended with graphene oxide (GO) and PES blended with GO functionalized with photoactive semiconductor catalyst (TiO2 and ZnO). The antifouling and self-cleaning properties of composite membranes were also investigated. The GO was prepared from natural graphite powder by oxidation method at low temperature. TiO2 ...

  • 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 ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • Case study - Bakery ethanol

    Overview A bread and bun bakery was faced with installing air pollution control equipment to control the volatile organic compounds (VOCs) emitted during their baking process. The local regulatory agency requires bakeries that generate over 25 tons of ethanol per year to reduce emissions by 95% by installing control devices on their ovens. The airstream that needed to be treated included ...

  • Case study - ETO sterilizer abatement
