  1. 11. 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

  4. 13. Volatile fatty acid production and application as external carbon source for denitrification

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Cora Michelle Döhler; [2020]
    Keywords : VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Abstract : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  5. 14. Feedstock Recovery From Municipal Food Waste

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

    Author : Matilda Palmér; Anna Sandström; Sara Johansson; Josefin Eklund Wallin; [2020]
    Keywords : Feedstock Recovery; Food waste; Sludge; Anaerobic digestion; VFA;

    Abstract : Volatile Fatty Acids (VFAs) are a by-product when producing methane through anaerobic digestion (AD). Due to their many uses as building block chemicals, it is of interest to look into ways to optimize anaerobic digestion toward VFA production instead of methane generation. READ MORE

  6. 15. 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
