  2. 1. Hydrodynamic modelling of microbial water quality in drinking water sources

    Author : Ekaterina Sokolova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; faecal contamination; QMRA; faecal indicators; pathogens; risk assessment; microbial source tracking; Bacteroidales; E. coli;

    Abstract : The faecal contamination of water sources can cause waterborne disease outbreaks among drinking water consumers. To design drinking water treatment and minimise consumer health risks, knowledge on source water quality is needed. READ MORE

  4. 2. Hygiene Aspects of Greywater and Greywater Reuse

    Author : Jakob Ottosson; KTH; []
    Keywords : greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

    Abstract : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. READ MORE

  5. 3. Hydrodynamic and Microbiological Modelling of Water Quality in Drinking Water Sources

    Author : Ekaterina Sokolova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECO Lab; Bacteroidales; inactivation; microcosm experiment; fate and transport modelling; pathogens; microbial source tracking; MIKE 3; faecal indicators;

    Abstract : Faecal contamination of drinking water sources poses risks for waterborne disease outbreaks. To manage these risks the fate and transport of faecal contamination in a drinking water source need to be understood and quantitatively described. READ MORE

  6. 4. Increasing the impact and sustainability of safe drinking water supply systems in rural Bangladesh : Randomized experiments with interventions in project life cycle

    Author : Md. Ahasan Habib; Prosun Bhattacharya; Anna Tompsett; Mushfiq Mobarak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Randomized Experiment; Safe Drinking Water; Participation; Decision-Making; Contribution Requirements; Cost-effectiveness; Faecal Coliform; Arsenic; Tubewell; Cleaning; Maintenance; Impact; Sustainability; Bangladesh; Randomiserat Experiment; Säkert Dricksvatten; Deltagande; Beslutsfattande; Bidragskrav; Kostnadseffektivitet; Fekal Koliform; Arsenik; Tubewell; Rengöring; Underhåll; Påverkan; Hållbarhet; Bangladesh; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Tillgång till rent dricksvatten är en global utmaning, vilket återspeglas i hållbar utvecklingsmål 6. I Bangladesh är det en brådskande fråga att överbrygga klyftan mellan de som har säkert hanterat dricksvatten och de med förbättrade källor. READ MORE

  7. 5. Evaluation of microbial health risks associated with the reuse of source-separated humna urine

    Author : Caroline Höglund; KTH; []
    Keywords : urine-separation; urine; wastewater systems; wastewater reuse; recycling; enteric pathogens; faecal sterols; indicator bacteria; hygiene risks; microbial persistence; microbial risk assessment; QMRA; fertiliser; crop;

    Abstract : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.
