  • Zuser - Polaris 2800 - With Lindner, you know what you’re getting - Case Study

    Zuser Ressourcenmanagement GmbH is not keen on experiments: for the past 24 years the RDF producer in Peggau, Austria has bought shredders made by Lindner Recyclingtech. The new addition to the family is a Polaris 2800. For one-step shredding every other machine was simply out of the question. The cooperation with Lindner dates back to a time before Mag. Georg Zuser became CEO of the Zuser ...

  • Application of image processing on struvite recovery from swine wastewater by using the fluidized bed

    Fluidized granulation is one of the common methods used in wastewater treatment and resource recovery with harvesting millimeter-scale large particles. Presently, effective methods are lacking to measure the fluidized granules ranging from micro- to millimeter scales, with the consequence of ineffectively controlling and optimizing the granulation process. In this work, recovering struvite ...

  • High-rate nitrification of electronic industry wastewater by using nitrifying granules

    Nitrifying granules have a high sedimentation property and an ability to maintain a large amount of nitrifying bacteria in a reaction tank. Our group has examined the formation process of nitrifying granules and achieved high-rate nitrification for an inorganic synthetic wastewater using these granules. In this research, a pilot-scale test plant with an 850-liter reaction tank was assembled in ...

  • Case study - Aluminium Scrap Decoating US Granules (USA) 2001

    HCl emissions reduced from 1000mg/Nm3 to 5mg/Nm3.  Process: To recover aluminium scrap from plastic foil. A Glosfume high temperature ceramic filter system replaced an existing bag filter that had suffered severe corrosion. This was due to being operated at low temperatures, combined with extremely high HCl levels, during aluminium scrap decoating. Lime injection ...

  • Promotion of partial nitritation-anammox process by improving granule proportion

    For enhancing the partial nitritation-anammox (PN/A) process, the effects of granule fraction on system performance were investigated in this study. Two sequencing batch reactors (SBRs) were inoculated with PN/A biomass with a floc mass fraction of 53%. In SBR1, when the nitrogen removal rate (NRR) was stable, flocculent sludge was gradually discharged from the reactor using a screen, and the ...

  • Tire Shredders: An Introduction

    How Does a Tire Shredding Machine Work? Tire shredding is a very common way of preparing scrap tires for disposal or recycle. In order to dispose of tires in a landfill, they must be shredded to various sized chips. The size required depends on the state or area you live in. Tire shredding is also used for recycling tires; crumb tire or tire mulch can be reused to create surfaces on ...

  • Short-term temperature impact on simultaneous biological nitrogen-sulphur treatment in EGSB reactor

    Sulphides are present in many wastewater streams; their removal is important due to corrosiveness, toxicity and unpleasant odour, and can be carried out by anaerobic biological treatment. This study focuses on the temperature effect (25–10 °C) on an expanded granular sludge bed (EGSB) reactor for sulphide removal using nitrate as electron acceptor. The reactor was run at a ...

  • Filtration media: Shapes and manufacturing processes

    The shape of the filtration media and the production process directly affect the absorption capacity of the granulate and consequently the efficiency of filtration. Granules in the shape of a pellet (cylinder) do not facilitate such a high degree of compaction as spherical granules, so that the passage of the air flow becomes easier, ...

  • Impact of aluminum chloride on process performance and microbial community structure of granular sludge in an upflow anaerobic sludge blanket reactor for natural rubber processing wastewater treatment

    In this study, granular sludge formation was carried out using an aluminum chloride supplement in an upflow anaerobic sludge blanket (UASB) reactor treating natural rubber processing wastewater. Results show that during the first 75 days after the start-up of the UASB reactor with an organic loading rate (OLR) of 2.65 kg-COD·m−3·day−1, it performed stably with a removal of 90% of the ...

  • Transprotekt Ethylene Filters

    Bioconservacion's ethylene filters have a new look! Recently Bioconservacion changed the appearance of its Transprotekt filters for ethylene absorption in order to make identifying them easier at all times, from the point of origin to the destination. The new filters have colour coding so that the type of filtration granule being used can be readily ...

  • Optimization of total trihalomethanes' (TTHMs) and their precursors' removal by granulated activated carbon (GAC) and sand dual media by response surface methodology (RSM)

    A response surface methodology (RSM) applying central composite design with rotatable full factorial (14 non-center and six center points) was used to discern the effect of granular activated carbon (GAC), sand and pH on total trihalomethanes (TTHMs) and humic acid (HA) removal from drinking water. Results showed efficient TTHMs and HA removal by GAC while a sand column showed little effect ...

  • Coating of Plastic Granules - case study

    In order to increase the production output of extruders and injection moulding machines, the flow and processing characteristics of plastic granules have to be modified. Especially for polyamides (PA) and polystyrene (PS) this occurs by means of powdering (coating) with powder additives. In doing so, two different methods are common. The pure dry mixing of plastic granules with the powder ...
