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. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Virginia Tosi; [2021]
   Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

   Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

4. 3. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

   University essay from SLU/Department of Molecular Sciences

   Author : Jessica Sellin; [2021]
   Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

   Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

5. 4. Hydrodynamic cavitation applied to anaerobic degradation of fats, oils and greases (FOGs)

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Johan Lunnbäck; [2016]
   Keywords : FOG; Hydrodynamic cavitation; Anaerobic digestion; Pre-treatment; Oil emulsion;

   Abstract : To increase profitability for biogas production, new innovative substrates and condition of operations needs to be implemented. At the current state, fats, oils and greases (FOGs) represent a promising substrate even though it brings operational challenges to the anaerobic digestion process. READ MORE

6. 5. Stable increase of organic loading rate in anaerobic membrane bioreactors working at ambient temperature

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Jean Monhonval; [2015]
   Keywords : environmental engineering; anaerobic membrane bioreactor; stability indicators; ambient methanization; stable increase organic loading rate; vattenförsörjningsteknik; avloppsteknik; water engineering; Technology and Engineering;

   Abstract : Anaerobic processes are an interesting alternative to treat wastewaters instead of aerobic treatments as it allows recovery of energy with the produced biogas while removing organic matter. In the industry, lots of low-strength industrial wastewaters are available and unused for biogas production due to their low concentration of organic material and high volumes (slaughterhouse wastewaters, dairies and beverages industries, oils and fats producers).
