  1. 1. Anaerobic Treatment of Agricultural Residues and Wastewater - Application of High-Rate Reactors

    Författare :Wilson Parawira; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; opaque beer brewery wastewater; UASB; two-stage; co-digestion; sugar beet leaves; solid potato waste; methane yield; biogas; Anaerobic digestion; agricultural residues;

    Sammanfattning : The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. LÄS MER

    Sammanfattning : This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp. LÄS MER

  4. 3. Reactor Applications and Process Monitoring for Improved Anaerobic Digestion

    Författare :Tor Gunnar Jantsch; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH-indicators; spectrophotometric; Biotechnology; Bioteknik; alkalinity; monitoring; UASB reactor; spent sulphite liquor; caustic extraction liquor; sulphite evaporator condensate; pulp wastewater; Anaerobic digestion; biogas;

    Sammanfattning : Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy.
