  1. 1. 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

  2. 2. Composition and dynamics of the bacterial community in aerobic granular sludge reactors

    Författare :Enikö Barbara Szabo; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; qPCR; sequencing batch reactors; microbial community composition; T-RFLP; functional groups; Illumina MiSeq; wastewater; aerobic granular sludge; nitrogen removal; population dynamics;

    Sammanfattning : The aerobic granular sludge (AGS) technology is probably the future standard for wastewater treatment, due to its low footprint and low energy consumption. Although achieving granulation is usually not a challenge anymore, our understanding of the community assembly during start-up, and of the microbial ecology of these reactors in general, is incomplete.

  3. 3. 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

  4. 4. Removal of Organic Micropollutants from Wastewater in Biofilm Systems

    Författare :Cecilia Burzio; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Micropollutants; Aerobic Granular Sludge; Sorption; Biological Treatment; Pharmaceuticals;

    Sammanfattning : The presence of organic hazardous substances in the aquatic environment, such as pharmaceutically active compounds and personal care products, has become a worldwide issue of increasing environmental concern. Present at concentration of nano- to milligram per liter, they are defined as organic micropollutants (OMPs). LÄS MER
