  2. 2. Downstream Processing Using Membrane Technology

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Anna Persson; Lund University.; Lunds universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biochemical technology; Chemical technology and engineering; Protein A; Bovine serum albumin; Lactic acid; Electrodialysis; Ultrafiltration; Microfiltration; Downstream processing; Membrane; Biokemisk teknik;

    Sammanfattning : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. LÄS MER

  3. 3. Recovery of Hemicelluloses Extracted from Spruce and Wheat Bran : Membrane Filtration Process Development and Cost Estimates

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Johan Thuvander; Lund University.; Lunds universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemicelluloses; Membrane filtration; Galactoglucomannan; Arabinoxylan; Microfiltration; Ultrafiltration; Spruce; Wheat bran; Hemicellulosa; Membranfiltrering; Mikrofiltrering; Ultrafiltrering; Arabinoxylan; Galactoglucomannan; Gran; Vetekli;

    Sammanfattning : Hemicelluloses are a group of abundant polymers found in all plants and constitute about one third of the total plant biomass. These polymers can be used in many different products, such as oxygen barrier films, emulsifiers, foams and probiotic food additives. LÄS MER

  4. 4. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions

    Detta är en avhandling från Food Technology, Engineering and Nutrition, Lund University

    Författare :Ingmar Harald Huisman; Lund University.; Lunds universitet.; [1998]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ceramic membranes; shear-induced diffusion; crossflow microfiltration; silica particles; zeta potential; Livsmedelsteknik;

    Sammanfattning : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. LÄS MER

  5. 5. Extraction and Isolation of Hemicelluloses from Agricultural and Forestry Waste Streams

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Tobias Persson; Lund University.; Lunds universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : New methods and products must be developed to reduce our dependency on fossil fuels, to reduce global warming. In this work, methods of extracting and isolating hemi¬celluloses from agricultural and forestry waste streams have been studied. LÄS MER
