  1. 16. 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/Akademin för ekonomi, samhälle och teknik

    Author : Ibrahima Sory Gärdeklint 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

  3. 17. Life cycle assessment of industrialized lithium-ion battery recycling : Mechanical and hydrometallurgical treatment from an ex-ante perspective

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Jonathan Balsvik; [2020]
    Keywords : Environmental impact; climate change; carbon footprint; up-scaling; end-of-life; waste management;

    Abstract : As the use of lithium-ion batteries exponentially increases through demand for electric vehicles and energy storage systems, so will the need for end-of-life treatment subsequently increase. Recycling the valuable materials from batteries in an efficient and extensive fashion could decrease the environmental impacts of batteries. READ MORE

  4. 18. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emma-Helena Ericsson; [2020]
    Keywords : AOX; EOX; wastewater treatment plant; column test; granular activated carbon; natural zeolites; Polonite r ; Zugol;

    Abstract : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. READ MORE

  5. 19. Studie av effekterna efter behandling mot viltarbete i plantskog i östra Götaland

    University essay from SLU/School for Forest Management

    Author : Elias Tallgren; Henrik Andersson; [2020]
    Keywords : Viltskador; Viltmedel; Plantering;

    Abstract : iv Abstract For many years, the game has been a problem when establishing new forest, which over the years has not become an easier task in traditional forestry. The number of new game species has increased, and the hunters have not been able to keep the populations down. READ MORE

  6. 20. Investigation of carbon capture technologies for Sävenäs waste-to-energy plant

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jasmine Andersson; [2020]
    Keywords : CCS; flue gas treatment; waste incineration; energy balance; emission abatement;

    Abstract : Carbon capture technologies have the potential to decarbonize the emissions to air from the heat and power sector and contribute to the necessary greenhouse gas emission mitigation in order to meet the Paris Agreement requirements. The energy requirement and ability to retrofit carbon capture units are crucial to convert existing power plants into more environmental benign processes to meet the Swedish national goal of greenhouse gas neutrality at 2045.
