1. 1. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Harry Tibbetts; [2023]
   Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

   Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

3. 2. 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

4. 3. Anaerobic Co-Digestion Of Food Waste And Kraft Pulp Fibre To Enhance Digestate Dewaterability

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Kwame Boateng Agyemang; [2021]
   Keywords : Anaerobic digestion; Digestate; Dewaterability; Food waste; Pulp fibre;

   Abstract : Digestate produced during anaerobic digestion of food waste is recognised as a good alternative to mineral fertilizer which could also be used to amend soil properties. This has conventionally been applied directly and unprocessed to nearby farms or processed and transported elsewhere. 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. high loaded anaerobic mesophilic digestion of sewage sludge : An evaluation of the critical organic loading rate and hydraulic retention time for the anaerobic digestion process at Käppala Wastewater Treatment Plant (WWTP).

   University essay from Mälardalens högskola/Framtidens energi

   Author : Ibrahima Sylla; [2020]
   Keywords : Dewaterability; Mesophilic anaerobic digestion; Methane; Organic load rate; Renewable energy source; Sludge filterability; Wastewater treatment.; Avvattningsförmåga; mesofil anaerob rötning; metan; organisk belastning; förnybar energikälla; slammets filtrerbarhet; vattenrening;

   Abstract : Käppala wastewater treatment plant (WWTP) has, during a few years, observed an increase in organic loading rate (OLR) in the mesophilic anaerobic digester R100, due to an increased load to the WWTP. The digestion of primary sludge at Käppala WWTP is today high loaded, with a high organic loading rate (OLR) and low hydraulic retention time (HRT). READ MORE
