  • Case study - Organic particulate filtration

    Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog ...

  • The economic benefits of HEPA-grade filtration for gas turbine operation in the power generation industry

    Everywhere we look these days, one message stands above all the rest: energy must be used with greater efficiency Global energy demand is estimated to rise between 25 and 30 percent between now and 2040, fueled by growth in economic output and by a growing population in which billions of people —despite working hard to advance their standards of living — subsequently and inevitably ...

  • Hydraulics stability of compost-based filtration media

    The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or ...

  • Downflow filtration technology keeps contaminants at bay

    Just south of present day Lumpkin, GA, you can visit a reconstructed community from the 1850s and experience a taste of everyday life from that time period. In dramatic contrast, you will also find one of the water and wastewater industry’s most advanced filtration technologies in this same area. This technology was installed specifically to protect the Lumpkin area from the damaging effects of ...


  • BHP Billiton - cooling water treatment & solids filtration

    Client: BHP Billiton Douglas CETCO Oilfield Services was requested to supply a water treatment package to treat heavily contaminated water in-line. Consequently CETCO’s equipment had to operate at pressures of up to 15.5 bar and temperatures of 120°C. Following lab bench studies and a technical onsite evaluation, CETCO modified an existing RFV 3000 adsorption skid to carry out this unique closed ...
