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

    Författare :Michael Cimbritz; Avdelningen för kemiteknik; []
    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

  3. 2. Modern Artificial Recharge Plants : Combining chemical flocculation with aquifer recharge

    Författare :Kristofer Hägg; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Chemical flocculation; Ultrafiltration membrane; Disc filtration; Managed Aquifer Recharge;

    Sammanfattning : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. LÄS MER

  4. 3. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

    Författare :Janne Väänänen; Avdelningen för kemiteknik; []
    Nyckelord :coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

    Sammanfattning : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. LÄS MER

  5. 4. Application of ozone in wastewater treatment : For mitigation of filamentous bulking sludge & reduction of pharmaceutical discharge

    Författare :Filip Nilsson; Avdelningen för kemiteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

    Sammanfattning : Wastewater treatment with activated sludge is the most common way of treating wastewater. The process relies on bacteria converting nutrients, BOD and COD into biomass, CO2 and N2. Even though the configuration of activated sludge processes and wastewater treatment plants varies there are common problems which are shared. LÄS MER

  7. 5. Proteome studies, with emphasis on the kidney glomerulus

    Författare :Sam Tryggvason; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Proteomics aims to link genes to protein expression and function. Proteomics is a very versatile and technology-dependent discipline and the development of mass spectrometry-based proteomics has advanced the understanding of the complex and dynamic nature of proteomes. LÄS MER
