  1. 1. Microbial Ecology of Granular Sludge

    Författare :Raquel Liebana; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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

  3. 2. Removal of Micropollutants from Wastewater in Aerobic Granular Sludge and Activated Sludge Systems

    Författare :Cecilia Burzio; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Pharmaceuticals; Aerobic Granular Sludge; Microbial Community; Organic Micropollutants; Biofilm; Transformation; Sorption;

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

  4. 3. Application of aerobic granular sludge for municipal wastewater treatment - Process performance and microbial community dynamics under fluctuating conditions

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy usage; aerobic granular sludge; sequencing batch reactors; granulation; municipal wastewater treatment; nutrient removal; start-up; microbial community dynamics; full-scale operation; low temperature; activated sludge;

    Sammanfattning : Pressures of growing cities, competition for use of urban areas and higher influent loads, are pushing for innovative technologies for wastewater treatment with low demands for land footprint and costs. Furthermore, wastewater treatment is needed to move towards a circular economy by harvest of valuable resources such as nutrients and energy. LÄS MER

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

    Författare :Enikö Barbara Szabo; Chalmers tekniska högskola; []
    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.

  7. 5. Microbial Community Assembly during Aerobic Granulation

    Författare :Raquel Liebana; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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
