  1. 16. 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

  3. 17. 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

  4. 18. A study on the effects on a wastewater treatment plant when recovering the heat from the wastewater

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : SUSANNE BERGSTRAND; [2020]
    Keywords : ;

    Abstract : source of thermal energy. Wastewater as a source of energy has gotten more attention in recent times, as the Sustainable Development Goals in combination with local challenges encourage new technical solutions that can replace old and outdated technology. READ MORE

  5. 19. Potential for mitigating GHG emissions at a Swedish wastewater treatment plant – a life cycle approach

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Nina Aldén; [2020]
    Keywords : GHG emissions; Wastewater treatment; Sewage sludge; Life cycle analysis; Mitigation; Carbon footprint; Global warming potential;

    Abstract : To meet the national and international climate goals every potential GHG mitigating effort needs to be addressed. The aim of this thesis is to investigate if the wastewater treatment plant (WWTP), Ekebyhov, can reduce its GHG emissions by making changes inthe treatmentprocess. The main GHGs emitted from WWT areN2O, CH4and CO2. READ MORE

  6. 20. Mainstream Deammonification process monitoring by bacterial activity tests

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andrea Carranza Muñoz; [2020]
    Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE
