  • Case study -New media makes RTO natural gas usage a rarity!

    Overview Tekra Corporation has always had an eye on their energy conservation. They are a custom coater of plastic films in Wisconsin where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early ...

  • When It Comes to Screening Media, Quality Matters

    In precise industrial processes, all equipment and constituent parts must work together to drive performance and efficiency. For screening and sifting materials in the pharmaceutical, chemical, aggregate and other industries, your choice of media goes a long way toward determining the effectiveness of your machines. Even the best vibratory sifters are only ...

  • Calculation of ceramic pot filter hydraulic conductivity using falling-head data

    Flowrate is used as a predictor of ceramic pot filter (CPF) disinfection effectiveness, and the relationship between flowrate and porosity has been examined in several studies. However, hydraulic conductivity, not porosity, is the constant of proportionality that describes flow through porous media. Equations have been developed to estimate the hydraulic conductivity of CPF side walls and bottom ...

  • Nitrification/denitrification in swine wastewater using porous ceramic sticks with plastic rings as supporting media in two-stage fixed-biofilm reactors

    This study evaluated the performance of oxic-anoxic fixed-biofilm reactors (FBRs) using porous ceramic sticks with plastic rings as supporting media for nitrogen and organic carbon (as COD) removal from swine wastewater. Experimental results indicate that the removal efficiency of NH4+-N increased to 86–92% from 52–98% as the volumetric ammonium-nitrogen loading rate increased to 0.25 kg ...

  • Basic Principles of Microfiltration

    Microfiltration can be defined as the separation of particles of one size from particles of another size in the range of approximately 0.01 µm through 20 µm. The fluid may be either a liquid or a gas. Microfiltration media are available in a wide variety of materials and methods of manufacture. They can be rated either 'absolute' or 'nominal' depending upon the percentage of capture of particles ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?

    Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...
