  1. 11. Phosphorus removal in reactive filter materials : factors affecting the sorption capacity

    Författare :Charlotte Nilsson; Gunno Renman; Lena Johansson Westholm; Aleksandra Drizo; Annelie Hedström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Phosphorus is an essential component in all living organisms; it is one of the components of the DNA and the key element in the energy supplying molecule adenosine triphosphate (ATP). Throughout the history, humans have been recycling phosphorus to agriculture; thereby increasing the yield, examples of this includes the burning of plants and the use of manure. LÄS MER

  3. 12. Uptake and fate of pathogenic microbes in the blue mussel, Mytilus edulis

    Författare :Bodil Hernroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mytilus edulis; bivalve; immune response; lipopolysaccharide; LPS; antimicrobial peptide; gamma camera; radiolabelling; Salmonella typhimurium; sanitary safety; public health;

    Sammanfattning : Bivalves, like the blue mussel Mytilus edulis, are filter-feeders and can therefore accumulate high numbers of microbes from the surrounding water. These shellfish are considered the main risk for bringing pathogens from domestic outlets in the sea, back to the community. LÄS MER

  4. 13. Quantitative monitoring of microorganisms in environmental samples using biomarkers

    Författare :Annelie Elväng; James Prosser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : The use of microorganisms in environmental biotechnology is an area of growing interest. Microorganisms have been used for diverse applications, such as biological fertilizers, biological pesticides and bioremediation of toxic chemicals. In many cases, the bacteria of interest have been genetically alterred to improve certain traits. LÄS MER

  5. 14. 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

  7. 15. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

    Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Arve Heistad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small-scale; sand filter; phosphorus filter; package plant; blackwater; greywater; urine diversion; multi-criteria; composite sample; VA-teknik; Urban Water Engineering;

    Sammanfattning : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems. LÄS MER
