  1. 11. Pre-acidification of a Synthetic Dairy Wastewater in Continuously Stirred Tank Reactors

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Can Xiong; [2019]
    Keywords : pre-acidification process; hydraulic retention time; soluble chemical oxygen demand transformation into fermentation product; volatile fatty acids; distribution; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : Two-stage anaerobic digestion is considered as a sustainable and efficient way to deal with dairy effluent, and is commonly applied. The pre-acidification happening during the first stage of this process could be used to buffer the complex conditions in the initial dairy effluent, as well as produce intermediary product such as volatile fatty acids (VFA), and it is essential to be controlled.

    Keywords : biogas; electric bus; public transport; road transport; sea transport; industry; electricity; heat; policy instruments; biogas; elbuss; kollektivtrafik; vägtransporter; sjöfart; industri; elektricitet; värme; styrmedel;

    Abstract : Biogas is largely utilised as vehicle fuel in public bus transport in Sweden today. This study investigates opportunities and barriers for continued domestic use and production of biogas, in relation to the ongoing electrification of public bus transport. READ MORE

  4. 13. Towards a prototype of a modular biogas system

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

    Author : Arvid Emilsson; Andreas Buhrgard; [2019]
    Keywords : Biogas; Vehicle gas; CHP; micro-CHP; farm-based; energy audit; techno-economic analysis; energy evaluation; upgrading; water-scrubber; small-scale; scalable; stand-alone; mass-production;

    Abstract : As of today, large unused potential for biogas production exist within the Swedish agriculture sector. The biogas production within this sector is, however, associated with several problems such as poor energy efficiency and non-profitable systems. This is to some degree due to lack of standardized technical solutions. READ MORE
