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

    Author : Cecilia Burzio; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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). READ MORE
