  1. 1. Improved life cycle assessment of wastewater and sludge management with resource recovery

    University dissertation from Chalmers University of Technology

    Author : Sara Heimersson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; wastewater treatment; sludge treatment; sludge handling; biosolids; resource utilisation; allocation; pathogen risks;

    Abstract : Around the world every day, large amounts of wastewater are treated before release, to avoid impacts on humans and the environment. The treatment requires resources in the form of energy and chemicals, and it generates large amounts of sewage sludge, however, it can also serve as a source of energy, nutrients and carbon.

  2. 2. Fresh Perspectives on the Assessment of Sewage Sludge Management

    University dissertation from Chalmers University of Technology

    Author : Robin Harder; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; life cycle assessment; risk assessment; life cycle impact assessment; wastewater; sewage sludge; biosolids; pathogen risk; human toxicity; chemical risks; land application;

    Abstract : Sewage sludge management and its role in closing nutrient cycles have received considerable attention in recent years. This thesis quantified phosphorus flows in Gothenburg, Sweden, under current and possible future waste management practices, and aimed to improve the assessment of wastewater and sludge management from an environmental and human health perspective through blending risk assessment (RA) and life cycle assessment (LCA).

    University dissertation from Chalmers University of Technology

    Author : Johan Åström; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vattenteknik; Water engineering; Matematisk statistik; Mathematical statistics; Mikrobiologi; Microbiology; Mikrobiologi; Microbiology; Miljöteknik; Environmental engineering; Pathogens; QMRA; Surface water; Flow-weighted sampling; qPCR; Bacteroidales; Bifidobacteria; Microbial source tracking; Stochastic modelling; Cryptosporidium.;

    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

  4. 4. Microbial risk assessment and its implications for risk management in urban water systems

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Therese Westrell; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; INTERDISCIPLINARY RESEARCH AREAS Water in nature and society; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vatten i natur och samhälle;

    Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE

  5. 5. Physiological integration and morphological plasticity in extensive clonal plants

    University dissertation from Plant Ecology, Ecology Building, SE-223 62 Lund

    Author : Tina D'Hertefeldt; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Maianthemum; Carex; Clonal plants; tracers; Växtekologi;

    Abstract : Popular Abstract in Swedish Fysiologisk integrering och morfologisk plasiticitet i stora klonala växter Många av våra vanligaste växter är klonala, dvs de kan producera avkommor utan sexuell befruktning. Hit räknas blåbär och lingon, många av våra vårväxter som tex. vitsippa och flera av våra värsta ogräs, som kvickrot och kirskål. READ MORE
