  2. 1. Wastewater discharges and microbial variability in a surface water source

    Author : Johan Åström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; faecal indicators; pathogens; drinking-water; microbial risk assessment; variability; rainfall; catchment; wastewater; surface water; Hazardous events;

    Abstract : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. READ MORE

  4. 2. Benchmark Simulation Model for Integrated Urban Wastewater Systems : Model Development and Control Strategy Evaluation

    Author : Ramesh Saagi; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Benchmark Simulation Model; Integrated control strategies; Integrated modelling; River water quality;

    Abstract : The integrated urban wastewater system (UWS) consists of different sections that are interconnected. These include: i) catchment; ii) sewer network; iii) wastewater treatment plant (WWTP); and finally, iv) receiving water system. Traditionally, these sections are operated and evaluated individually.

  5. 3. 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

  6. 4. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

    Author : Estevao Pondja; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coal mining; acid mine drainage; mine water treatment; climate change; low-cost adsorbent;

    Abstract : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. READ MORE

  7. 5. Microbial Risks in Surface Water Sources

    Author : Johan Åström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface water; Bifidobacteria; Microbial source tracking; Cryptosporidium.; QMRA; Flow-weighted sampling; Pathogens; Bacteroidales; Stochastic modelling; qPCR;

    Abstract : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. READ MORE
