    Sammanfattning : To develop anaerobic digestion (AD), innovative solutions to increase methane yields in existing AD processes are needed. In particular, the adoption of low energy pre-treatments to enhance biomass biodegradability is needed to provide efficient digestion processes increasing profitability. LÄS MER

  2. 7. Material Flow Analysis of Phosphorous and Organic Matter in Domestic Wastewater and Food Waste in Sông Công Town, Vietnam

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik; Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Olli Sammalisto; Zanna Sefane; [2015]
    Nyckelord :;

    Sammanfattning : Vietnam’s fast economic growth has to a large extent been achieved on the expense of a rapid deterioration of the natural environment, including eutrophication of local water sources. Proper planning is needed to move towards a sustainable wastewater management and one recognized tool for such planning is material flow analysis (MFA). LÄS MER

  3. 8. An investigation for a method for measuring microbial degradation for oxochlorates in waste water sludge

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Hoger Najem; [2015]
    Nyckelord :sludge;

    Sammanfattning : The oxochlorates, such as ClO4-, ClO3- and ClO2- are toxic compounds and therefore they must be removed from effluents. In general they are synthetic compounds from industries and naturally also presents in Chilean caliche. LÄS MER

  4. 9. Modelling the COD Reducing Treatment Processes at Sjölunda WWTP

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Tanya Klingstedt; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The main focus of this thesis was to evaluate the possibility of establishing a wastewater treatment model for the main COD removal parts in the water line of Sjölunda Wastewater Treatment Plant (WWTP) located in Malmö, in southern Sweden. The finalised model was used to simulate an increased load of on average 5,000 population equivalents (P.E. LÄS MER

  5. 10. Evaluation of Biological Hydrolysis Pre-treatment and the Biogas Potential of Sludge from Compact Waste Water Treatment

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Falk; [2015]
    Nyckelord :biological sludge hydrolysis; biogas; biochemical methane potential tests; compact waste water treatment; drum filter; anaerobic digestion; microfiltration; environmental engineering; water engineering; avloppsteknik; vattenförsörjningsteknik; Chemistry;

    Sammanfattning : Med anledning av de ökande utsläppskraven för avloppsreningsverk kommer ökade resurser i form av elektricitet och kemikalier att krävas om dagens teknologi ska användas även i fortsättningen. Följaktligen undersöks för tillfället mer effektiva metoder, vilka tillåter inte bara rening av avloppsvattnet utan även erbjuder en möjlighet att ta tillvara på de resurser som finns i avloppsvattnet.
