  1. 1. Filtration of Microcrystalline Cellulose: Electro-assisted filtration and the influence of surface properties

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jonas Wetterling; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filtration; modelling; compressible filter cakes; electroosmotic dewatering; electrofiltration; local filtration properties; electro-assisted filtration; solid-liquid separation; dead-end filtration;

    Abstract : One of the main requirements for the sustainable usage of materials is the use of renewable resources. This presents the Swedish forestry industry with the promising opportunity of using wood to produce not only traditional paper products but also a range of new materials of high value. READ MORE

  2. 2. On the local properties of compressible filter cakes

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Tuve Mattsson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local filtration properties; dead-end filtration; particle interactions; cake filtration; skin formation; constitutive relationships; modelling; solid-liquid separation;

    Abstract : Filtration as a means of separating solids from liquids is an important unit operation employed in a range of different industrial sectors, of which the forest products, mineral, chemical process and pharmaceutical industries are but a few. Accurate and applicable models for the filtration unit operation are imperative if industrial filtration equipment is to be designed correctly. READ MORE

  4. 4. On the determination and application of local filtration properties

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Peter Sedin; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemisk teknologi; Chemical Technology;

    Abstract : Filtration is a mechanical unit-operation used for the separation of liquid and solid. In this work, the three sub-operations cake build-up, expression and washing have been studied. One difficulty often encountered in the design of filtration equipment is that the materials being filtered form more or less compressible filter cakes. READ MORE

  5. 5. On the local filtration properties during cake filtration: Studies on LignoBoost lignin and the influence of ionic strength

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Julie Durruty; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost process; local filtration properties; dead-end filtration; softwood lignin; particles interactions; compressible filter cake; constitutive relationships;

    Abstract : The Kraft pulping technology has been thoughtfullyinvestigated and developed over the pasthundred years and more; it is currently the mostcommonly-used method ofpulping in the world. Anew and promising opportunity for Kraft pulp millswould be to take a step towards becomingbiorefineries by implementing technologies ableto extract and convert the organic by-products,such as lignin, into a wide rangeof value-added products and chemicals.
