  2. 21. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

    Author : Joanna Wawrzynczyk; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

    Abstract : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. READ MORE

  4. 22. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production

    Author : Valentine Nkemka; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam pretreatment; dry digestion; biogas; biohydrogen; Caldicellulosiruptor saccharolyticus; cadmium; anaerobic digestion;

    Abstract : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). READ MORE
