    Sammanfattning : BACKGROUND: The high prevalence of obesity in children and adolescents emphasizes the necessity to develop evidence-based treatment programs that are useful in a clinical setting. AIMS: The overall aim of the thesis was to develop and evaluate multidisciplinary approaches for management of children and adolescents with obesity. LÄS MER

  5. 5. Dissolved Air Flotation and Microscreening for Particle Separation in Wastewater Treatment

    Detta är en avhandling från Water and Environmental Engineering Department of Chemical Engineering

    Författare :Michael Cimbritz; Lund University.; Lunds universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; disc filtration; microscreening; DAF; wastewater treatment; particle separation; Chemical technology and engineering; particle size analysis; drum filtration;

    Sammanfattning : Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separation methods are of interest. LÄS MER
