1. 1. Resource recovery from wastewater treatment: challenges, opportunities and guidance for planning and implementation

   Författare :Mariana Cardoso Chrispim; Miklas Scholz; Marcelo Antunes Nolasco; Jennifer R. McConville; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; Resource recovery; Sewage; Planning; Water; Nutrient; Biogas; Developing countries; Urban areas;

   Sammanfattning : Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. LÄS MER

3. 2. Microbial Risks in Surface Water Sources

   Författare :Johan Åström; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

   Författare :Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

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

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

   Sammanfattning : 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.
