  1. 1. Downstream Processing Using Membrane Technology

    Författare :Anna Persson; Avdelningen för kemiteknik; []
    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. 2. Investigations on Membrane Fouling and Cleaning in Ultrafiltration Processes in Lignocellulosic Biorefineries

    Författare :Gregor Rudolph; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane fouling; Membrane cleaning; Ultrafiltration; Online monitoring; Galactoglucomannan; Wood extractives; QCM-D; Lignocellulosic biomass; pulp and paper;

    Sammanfattning : The current fossil-based economy must be transformed into a bio-based circular economy. A cornerstone of this transformation is the conversion of pulp and paper mills into lignocellulosic biorefineries that allow not only the production of pulp, paper, and electricity, but also novel biochemicals.
