  1. 1. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study

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

    Författare :Santiago Elejalde Bolaños; [2022]
    Nyckelord :thermophilic anaerobic digestion; volatile fatty acids; mixed sludge; organic loading rate; alkalinity; wastewater treatment plant; termofil rötning; flyktiga fettsyror; blandslam; organisk belastning; alkalinitet; avloppsreningsverk;

    Sammanfattning : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. LÄS MER

  2. 2. Anaerobic Co-Digestion Of Food Waste And Kraft Pulp Fibre To Enhance Digestate Dewaterability

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Kwame Boateng Agyemang; [2021]
    Nyckelord :Anaerobic digestion; Digestate; Dewaterability; Food waste; Pulp fibre;

    Sammanfattning : Digestate produced during anaerobic digestion of food waste is recognised as a good alternative to mineral fertilizer which could also be used to amend soil properties. This has conventionally been applied directly and unprocessed to nearby farms or processed and transported elsewhere. LÄS MER

  3. 3. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    Master-uppsats, KTH/Kemi

    Författare :Josephine Berg; [2021]
    Nyckelord :jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Sammanfattning : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. LÄS MER

  4. 4. Stimulating national biogas production : The case of Swedish agricultural wastemanagement

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Manoj Dammur; [2020]
    Nyckelord :Biofuels; renewable energy; biogas; Swedish biogas; biogas policies; policies as tools; Anaerobic digestion; waste treatment;

    Sammanfattning : Swedish state has been promoting alternative renewable fuels like biogas to reduce the dependency on fossil fuels and to curb related greenhouse gas emissions. Owing to many policies like subsidies and tax exemptions for using biogas, the country has seen a surge in demand for biogas. LÄS MER

  5. 5. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jonathan Andrén; [2018]
    Nyckelord :anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Sammanfattning : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.
