  • 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 ...

  • 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 ...

  • Recycled material as “raw material” for modern insulation material - case study

    AVA supplies horizontal batch mixing reactors as core production plant components for the manufacture of insulation boards and insulating materials made from rubber and cork granules. In addition to the excellent moistening of the rubber and cork granules with the binding agent, a particular feature is the complete emptying and good cleaning characteristics of the machine. For this purpose, AVA ...

  • 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 ...

  • Valorization of granulated slag of Arcelor-Mittal (Algeria) in cationic dye adsorption from aqueous solution: column studies

    A continuous adsorption study in a fixed-bed column was carried out using granulated slag (GS) as an adsorbent for the removal of methylene blue (MB) from aqueous solution. The effects of various parameters, such as initial dye concentration, flow rate, bed depth, and pH were investigated. Obtained results confirmed that the breakthrough time and exhaustion time were dependent on these ...

  • Hail damage assessment case study

    Service performed: Hail damage assessment Summary: Following a series of hailstorms that occurred in the Midwest U.S., EFI Global engineers quickly responded to conduct hail damage assessments for numerous commercial and residential buildings. Inspections of composition shingle roof coverings to determine the extent of hail damage included the use of random ...

  • Granulation of biological flocs under elevated pressure: characteristics of granules

    Aerobic granules (AG) have good settling ability and are relatively insensitive to the variation of organic loading rate. When sizes of granules become bigger, substrate and oxygen become limited in the granule core, leading to cell lysis and disintegration of granules. The higher the dissolved oxygen, the deeper the oxygen penetration inside AG. AG operated under elevated pressure might be a ...

  • Ask Yourself These Questions Before You Buy a Granulator

    Ask Yourself These Questions Before You Buy a Granulator 1 WHAT DO YOU WANT TO GRIND? * Consider: Type of part or sprue/runner system, type of material (hard/soft, brittle/tough, filled/unfilled), and temperature of parts being granulated. * Determines: Rotor design, horsepower, sound attenuation, ...

  • Mechanical Dryer for surface drying of plastic flakes & plastic granulates

    Neue Herbold - mechanical Dryer TM Series are used as a downstream component after a washing process. It is used for surface drying of the material fraction primarily for film flakes, granulate from PET bottles and other rigid types of plastics. The wet material ...

  • Intensive-washer for surface washing of the granulates an films

    The Intensive Washer IW Series from Neue Herbold is a centrifugal downstream unit for intensive cleaning of hard plastic granulates and films flakes. The pre-washed material is intensively washed; while passing the machine, it is thrown against the screen by centrifugal forces. Various screens determine the cleaning efficiency. The rotor of the intensive cleaner may be equipped with ...

  • Porous structure and spatial characteristics of aerobic granules

    Cryosectioned granules were observed in microstructure, Extracellur Polymeric Substances (EPS) and metal distribution. Aerobic granules composed of pores and channels that were not plugged by EPS, with rather open structure. Microorganisms proliferated mainly on the surface of granule and on the wall of channels, carbohydrate EPS mainly distributed on the surface of granules, and protein EPS ...

  • Effect of substrate feeding on viscosity evolution of anaerobic granular sludges

    This work aims to describe the effect of the feeding regime of anaerobic activity tests on the limit viscosity (μlim) evolution of the granules. Batch experiments were performed with 3 different sources of substrate: acetate, peptone, and glucose. Despite, the substrate origin was shown to affect the μlim evolution of granules, no clear relationship was found between the ...

  • Adsorption dynamics of cobalt [Co(ii)] on rubber granules

    The removal kinetics of Co(II) by waste tyre rubber granules was deliberated. Rubber granules (150300 µm) were used as sorbent. At the 4 mg/l and 15 g/l concentrations of Co(II) and adsorbent respectively, 83.2% removal was found in 180 min. Reaction kinetic followed a second order equation that was applied for the analysis of rate constant. At 30°C, rate constant was calculated to be ...

  • The headpiece domain of dematin regulates cell shape, motility, and wound healing by modulating rhoa activation

    RhoA is known to participate in cytoskeletal remodeling events through several signaling pathways, yet the precise mechanism of its activation remains unknown. Here, we provide the first evidence that dematin functions upstream of RhoA and regulates its activation. Primary mouse embryonic fibroblasts were generated from a dematin headpiece ...

  • Ecology and molecular adaptations of the halophilic black yeast Hortaea werneckii

    Molecular studies on halophilic adaptations have focused on prokaryotic microorganisms due to a lack of known  appropriate eukaryotic halophilic microorganisms. However, the black yeast Hortaea werneckii has been identifiedas the dominant fungal species in hypersaline waters on three continents. It represents a new model organism for studying the mechanisms of salt tolerance in eukaryotes. ...

  • Sorption of anionic surfactants on a fixed bed of rubber granules

    The performance of a fixed-bed adsorber (FBR) column for the removal of anionic surfactants from aquatic environments has been studied. Waste tyre rubber granules were used as the adsorbent material, and sodium dodecyl sulfate, an anionic surfactant, as the adsorbate. The FBR column design parameters were evaluated using the column breakthrough data at different bed depths. The Bohert and Adams ...
