  • 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 ...

  • Ethylene removal through oxidation in EthylClean Machines versus forced air through ozone

    Fruit constantly emits ethylene inside the chambers. To efficiently reduce the concentration of ethylene in these spaces, it needs to be eliminated at a speed that is faster than the production ratio of the fruit. This is achieved when the airflow that passes through the machines in one hour is equal to the volume of the chamber. Depending on the chamber's volume, Bioconservacion recommends ...

  • 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 ...

  • 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 ...

  • Metallurgy - Case Study

    By "metallurgy" we understand on the one hand the manufacture of metals, i.e. the metallurgy industry, and on the other hand, metal processing, i.e. the manufacture of high-performance materials from metal powders. AVA supplies mixers, granulators and dryers for these industries. Special heavy-duty mixers and granulators are used in the metallurgy industry. AVA has developed particularly ...

  • 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 ...

  • Shock resistance characteristic of a spiral symmetry stream anaerobic bio-reactor

    The shock resistance characteristic (SRC) of an anaerobic bioreactor characterizes the ability of the anaerobic community in the reactor to withstand violent change in the living environment. In comparison with an upflow anaerobic sludge blanket reactor (UASBR), the SRC of a spiral symmetry stream anaerobic bio-reactor (SSSAB) was systematically investigated in terms of removal efficiency, ...

  • Impacts of variable pH on stability and nutrient removal efficiency of aerobic granular sludge

    The impact of pH variation on aerobic granular sludge stability and performance was investigated. A 9-day alkaline (pH = 9) and acidic (pH = 6) pH shocks were imposed on mature granules with simultaneous chemical oxygen demand (COD), nitrogen and phosphorus removal. The imposed alkaline pH shock (pH 9) reduced nitrogen and phosphorus removal efficiency from 88% and 98% to 66% and 50%, ...

  • Extremely fast increase in the organic loading rate during the co-digestion of rapeseed oil and sewage sludge in a CSTR – characterization of granules formed due to CaO addition to maintain process stability

    In a co-digestion system running with rapeseed oil and sewage sludge, an extremely fast increase in the organic loading rate was studied to develop a procedure to allow for flexible and demand-driven energy production. The over-acidification of the digestate was successfully prevented by calcium oxide dosage, which resulted in granule formation. Mineralogical analyses revealed that the ...
