  1. 1. 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.

  3. 2. Effects of Organic Matter on Virus Removal with New and Used Sand in Tunåsen Infiltration Basin, Uppsala, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Stacy Sutliff-Johansson; [2015]
    Nyckelord :MS2; time-dependent removal; adsorption; organic matter effects; virus contamination; Uppsala; MS2; adsorption; organiskt material effekt; virus kontaminering; dricksvatten; Uppsala;

    Sammanfattning : Artificial infiltration has been increasing in popularity in Sweden as a way to combat over-abstraction of groundwater aquifers from growing municipalities. However, enteric virus contamination of drinking water sources is a concern as infiltrating surficial waters are easily contaminated from human activities. LÄS MER

  4. 3. Pathogen and indicator organisms removal in artificial greywater subjected to aerobic treatment : comparison of four filter media

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

    Författare :Ramiyeh Molaei; [2014]
    Nyckelord :Activated carbon; pine bark; biochar; BOD5 reduction; Enterococcous faecalis; greywater reuse; bacteriophage MS2; bacteriophage фX174; Salmonella spp;

    Sammanfattning : Treated greywater has a good potential to be used as a source of water. This study analyzes the removal of Salmonella spp., Enterococcous faecalis, bacteriophage ɸX174 and bacteriophage MS2 from greywater by filtration through biochar, bark, activated carbon and mixture of bark and activated carbon.
