  • Ceramic Polishing

    A company was using several chemistries to remove the total suspended solids (TSS) from their wastewater. The facility manufactures stainless steel surgical instruments. The wastewater is generated from the polishing/deburring of these instruments using an aluminum/ceramic polishing media. The jar tests shown are from the addition of the Floccin-H to the wastewater and moderate mixing. The TSS ...

  • 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 ...

  • Media replacement restores plant capacity and improves flow

    Reduced air flow capacity, large temperature imbalances in chambers, long start-up times, energy inefficiencies, and visual cracks and voids in the media bed are all indicators of an unhealthy Regenerative Thermal Oxidizer (RTO) that should be evaluated for media replacement. A recycling facility that processes waste bakery products was experiencing significant reductions in air flow capacity, ...

  • 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 ...

  • Review of Biofiltration Review of Biofiltration of Odors and Volatile Organic Compounds (Volatile Organic Compounds (VOCs VOCs)

    - Biofiltration of odors and volatile organicshas been practiced successfully for overthree decades - Media used in biofiltration can be categorizedinto two main types: * Natural Media –Compost, soil, peat * Synthetic Media –plastic, ceramic. - Currently, there is no systematic way ofcomparing the cost-performance of ...

  • 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 ...

  • Chemical Phosphorus Removal from Onsite Generated Wastewater

    ABSTRACT Phosphorus originating from onsite generated wastewater is becoming recognized as a major cause of impairment to streams and lakes. Efficient, low maintenance technologies are needed to reduce discharge levels. Removing phosphorus using luxury uptake or precipitation followed by settling, as is common at municipal wastewater treatment plants, is not practical for onsite generated ...

  • Repositioning vinyl flooring #310 case study

    Vinyl flooring had always been the lifeblood of this building products client. However, vinyl essentially had become a “no growth” category, losing market share to ceramic tile, wood and laminate. G&S created a communications strategy to “reinvent vinyl,” moving it from a dated product to a chic, youthful alternative. The client was positioned to consumer and trade ...


  • Case study - Oxidizer rebuild

    Industry Service and Maintenance Problem Anguil was called in to provide an engineering evaluation of a competitor's RTO that was suffering from visible deterioration and 'hot spot' issues. Due to the customer's production schedule, an internal inspection was not possible prior to the plant shutdown for repairs. Action ...

  • Case Study: Vibra-Drum grinding mill liner life

    Challenge The wear on conventional rotary grinding drum liners and media is very high. This is wear is due to the large number of forceful impacts caused by dropping of the material and media inside the drum during the course of processing. Approach General Kinematics design team set out to create a better grinding solution that would increase the ...

  • Comparing environmental impacts of tertiary wastewater treatment technologies for advanced phosphorus removal and disinfection with life cycle assessment

    Different technologies for tertiary wastewater treatment are compared in their environmental impacts with life cycle assessment (LCA). Targeting very low phosphorus concentration (50–120 μg/L) and seasonal disinfection of wastewater treatment plant (WWTP) secondary effluent, this LCA compares high-rate sedimentation, microsieve, dual media filtration (all with UV disinfection), and ...
