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

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

    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.

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

    Author : Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; 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

  6. 4. Phosphorus release and recovery from treated sewage sludge

    Author : Kristina Stark; Elzbieta Plaza; Bengt Hultman; Jes la Cour Jansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; Phosphorus release; Phosphorus recovery; Sludge fractionation; Supercritical water oxidation; Sustainable sludge handling.; Water engineering; Vattenteknik;

    Abstract : In working towards a sustainable society, recycling and recovery of products together with handling of scarce resources must be considered. The growing quantities of sludge from wastewater treatment plants and the increasingly stringent restrictions on landfilling and on agricultural use of sludge are promoting other disposal alternatives.

  7. 5. Forest industry sludge as a resource for energy recovery

    Author : Alina Hagelqvist; Ola Holby; Karin Granström; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Forest industries produce large amounts of carbon rich sludges as by-products in their processes. Presently sludge is treated as a poor quality biofuel for co-incineration, some mills treat it solely as a disposal problem. This thesis provides an introduction to production, composition and disposal issues of sludge. READ MORE
