  1. 1. 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

  3. 2. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Abdirahman Abdullahi; [2022]
    Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

  4. 3. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Johnny Hagelin; [2021]
    Keywords : Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

    Abstract : Research about resource recovery from complex waste streams is getting an increased scientific attention since valuable resources can be produced by sustainable biological means. In anaerobic degradation processes, resources such as volatile fatty acids (VFAs) and biogas are highly coveted. READ MORE

  5. 4. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Milton Matilde; [2020]
    Keywords : PEF; AD; biogas yield; sludge pre-treatment; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. READ MORE

  6. 5. Can organic waste provide sustainable fuel and energy in Rio de Janeiro? : An Early Assessment of waste-based biogas solutions in Rio de Janeiro, Brazil

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Jesper Lindmark; Lundqvist Oscar; [2019]
    Keywords : biogas; potential; feasibility; performance; environmental; economic; biogas solution; biogas solutions; waste-based; early assesment; multi-criteria framework; biogas; potential; genomförbarhet; prestanda; miljömässig; ekonomisk; biogaslösningar; hållbar utveckling;

    Abstract : Sustainable waste management remains a great challenge for many cities throughout the world. Landfilling is worldwide the most common way of treating municipal solid waste (MSW) and landfilling of organic matter releases the high potent gas methane, which contributes to global warming.
