    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  3. 2. Design and Analysis of Continuous Virus Inactivation Reactors in Biopharmaceutical Production

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Hanna Danielsen; [2020]
    Nyckelord :Chemical engineering; Kemiteknik; Virus inactivation; Chromatography; Technology and Engineering;

    Sammanfattning : The biopharmaceutical industry is replacing the current batch process with a continuous one and an essential step in the downstream process is the virus inactivation (VI). The challenge with a continuous VI reactor is to generate a narrow residence time distribution (RTD), while ensuring a precise incubation time. LÄS MER

  4. 3. Inactivation of viruses in water by chlorination using bacteriophages as model organisms

    Master-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Charan Raju Kanna; [2016]
    Nyckelord :desinfection; chlorination; bacteriophages; viruses; free chlorine;

    Sammanfattning : Climate change will lead to more extreme rain events in parts of Sweden resulting in sewage overflows and thus more contamination of surface water, leading to an increased risk of waterborne infections. Swedish and Norwegian surface waters are rich in humic substances with high organic carbon content that interferes with disinfection, the most important barrier to viruses in the water treatment plant.

  5. 4. Potential to inactivate microorganisms in sewage sludge by ammonia treatment : different temperatures and urea additions

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Fredrik Wirell; [2015]
    Nyckelord :Ammonia; Urea; Sewage sludge; inactivation; reduction; Thermo tolerant coliform bacteria; Salmonella; E. coli; Enterococci; Somatic coliphage;

    Sammanfattning : Sewage sludge is rich in nutrients and organic matter, both of which can be useful in the agricultural system. By recycling the nutrients from our excreta, a more sustainable use of nutrients in agriculture can be achieved and the use of mineral fertilizer can thereby be decreased. LÄS MER

  7. 5. Virus removal during artificial groundwater recharge and the effects of organic matter : Tunåsen infiltration basins, Uppsala, Sweden

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Lisanne Hölting; [2015]
    Nyckelord :drinking water; artificial groundwater recharge; bacteriophages; organic matter; adsorption;

    Sammanfattning : Die Verunreinigung von Trinkwasser mit pathogenen Mikroorganismen kann zu epidemischen Krankheitsausbrüchen führen und stellt daher weltweit ein Risiko für die menschliche Gesundheit dar. Oberflächengewässer sind im Gegensatz zu Grundwasser anfälliger für Verunreinigungen. LÄS MER
