  1. 1. Granulation and recycling of polymers

    Författare :Toni Reftman; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; akustik; vibrationer; vakuumteknik; granulation; granulators; recycling; size reduction; cutting resistance; hydraulics; Mechanical engineering; vacuum technology; vibration and acoustic engineering; hydraulik; Maskinteknik; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : The use of polymers and composite materials based on polymer matrix systems increases. With this raise the demands on recycling of both post-consumer and in house based material increase. The demands on the recycling process also increase. The reason is that the process more often has to be a part of the conventional production line. LÄS MER

  2. 2. Microbial Community Assembly during Aerobic Granulation

    Författare :Raquel Liebana; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

    Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER

  3. 3. Microbial Ecology of Granular Sludge

    Författare :Raquel Liebana; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

    Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER

  4. 4. Rheological modeling of particle flows in high shear granulation

    Författare :Mohammad Khalilitehrani; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; continuum modeling; rheology; disc impeller; high shear granulation;

    Sammanfattning : High shear granulation is an important process in a wide variety of applications, more specifically in pharmaceutical industries as a basic step in the tableting process. The process includes two major steps: dry high shear granulation and wet high shear granulation. It aims at producing granules with a specific size and material composition. LÄS MER

  5. 5. Continuum modeling of particle flows in high shear granulation

    Författare :Per Abrahamsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High shear granulation; parameter study; resolution dependence; continuum modeling; kinetic theory of granular flow; granular flow;

    Sammanfattning : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer.
