  1. 1. Characterization of a novel bacteriumoriginating from a biogas process

    University essay from SLU/Department of Molecular Sciences

    Author : Louise Welén; [2023]
    Keywords : biogas; ammonia-tolerance; mesophilic; characterization; bacterium;

    Abstract : An anaerobic bacterium, isolated from an enrichment culture originating from a biogas reactor operating at high ammonia conditions, was characterised via various tests. An analysis of the 16S rRNA gene confirmed that the closest relative was Desulfotomaculum halophilum with 92,5 % similarity. READ MORE

  3. 2. Isolation of an ammonia-tolerant syntrophic butyrate-oxidizing bacterium originating from a thermophilic biogas digester

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Malin Tiefensee; [2023]
    Keywords : thermophilic; ammonia-tolerant; syntrophic butyrate-oxidizing bacterium;

    Abstract : Syntrophic relationships between fatty acid degrading bacteria and hydrogenotrophic methanogens are important for a well-functioning anaerobic degradation process during biogas production from organic waste material. This is particularly important in biogas processes fed protein-rich material as their degradation gives rise to high levels of ammonia, which inhibits many microorganisms. READ MORE

  4. 3. Wastewater Treatment at Kraft Pulp Mills : Effect of temporary effluents and mitigation measures

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Hodda Shariatmadari; [2023]
    Keywords : ;

    Abstract : Large amount of water is used in the pulp-and-paper industry. Consequently, large amount of wastewater is produced in the various production processes. In general, the pollutants of concern involve organic compounds, nutrients, including nitrogen and phosphorous, suspended solids, and chlorinated compounds. READ MORE

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

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Abstract : 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. READ MORE

  6. 5. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fanny Blom; [2022]
    Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE
