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. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Louise Hjalmarsson; [2021]
   Keywords : hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

   Abstract : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. READ MORE

5. 4. Thermophilic anaerobic digestion of municipal wastewater sludges: A pilot scale evaluation with model assistance

   University essay from KTH/Kemiteknik

   Author : Ted Lundwall; [2021]
   Keywords : Thermophilic anaerobic digestion; Pilot; Municipal wastewater; Biogas; ADM1; Termofil rötning; Pilot; Kommunalt avloppsvatten; Biogas; ADM1;

   Abstract : I takt med att städerna växer ökar belastningen på de kommunala avloppsreningsverken. Käppalaförbundet förutspår att antalet anslutna personekvivalenter till Käppalaverket kommer att öka med över 160 % under de kommande tre decennierna. En ökad belastning leder till en större mängd slam som måste behandlas. READ MORE

6. 5. Impact on carbon emissions applying the sustainable EffiSludge wastewater treatment concept to the Nordic pulp- and paper industry

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Disa Donnér; [2018]
   Keywords : Anaerobic digestion; Biomethane; Carbon footprint; EffiSludge; Pulp- and papermill wastewater treatment; Waste activated sludge;

   Abstract : The pulp- and paper industry (PPI) faces a great challenge in finding new ways to reduce its overall carbon emissions. Large quantities of water are used in the pulp- and paper making process. In this context, a more sustainable wastewater treatment with a lower carbon footprint is of relevance for the PPI. READ MORE
