  1. 1. Assessing and optimizing biofilter performance in drinking water treatment

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

    Sammanfattning : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. LÄS MER

  3. 2. Acute limb ischaemia : Treatment, outcome and time trends

    Författare :Olivia Grip; Martin Bjöck; Clark Zeebregts; Uppsala universitet; []
    Nyckelord :Acute limb ischaemi; Treatment; Open revascularisation; Endovascular revascularisation; Outcome; Surgery; Kirurgi;

    Sammanfattning : Acute limb ischaemia (ALI) is a frequent emergency associated with high rates of amputation and death. Traditionally, patients with ALI were treated with open surgical removal of the occlusion or bypass surgery. During the past few decades, new endovascular techniques developed. LÄS MER

  4. 3. Efficient treatment of forest industrial wastewaters : Energy efficiency and resilience during disturbances

    Författare :Maria Sandberg; Karin Granström; Jonas Berghel; Alan Werker; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest industry; wastewater; oxygen transfer rate; black liquor; surface active; extractives; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : This work concerns the efficient treatment of wastewaters from pulp and paper mills by means of aerobic biological processes. For treatment processes there are many aspects of efficiency and the present study investigates both energy efficiency and purification efficiency during disturbances. LÄS MER

  5. 4. Partial renewal of granular activated carbon filters for improved drinking water treatment

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofiltration; Drinking water treatment; Spectroscopic properties; Granular activated carbon filter; Natural organic matter; Online monitoring; Fluorescence;

    Sammanfattning : Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. LÄS MER

  7. 5. Simulation and Optimization of Recirculating Aquaculture Systems

    Författare :Simon Pedersen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic modelling; optimization; biofilter; wastewater treatment; Recirculating aquaculture;

    Sammanfattning : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.
