  1. 1. Cake filtration : a study of non-reversible compressible materials

    Author : Mehdi Fathi-Najafi; Chalmers University of Technology; []
    Keywords : non-reversible compressible material; cake build-up; local filtration properties; simulation; cake filtration;

    Abstract : .... READ MORE

  2. 2. The influence of particle properties on cake filtration: Surface structure and surface charge

    Author : Jonas Wetterling; Chalmers University of Technology; []
    Keywords : surface structure; electrostatic particle interactions; cake filtration; solid-liquid separation; compressible filter cake; local filtration properties;

    Abstract : Solid-liquid separation is often a key process step when biomass is used as a raw material, and an energy efficient way of achieving solid-liquid separation is through cake filtration. However, many biomaterials present challenges when they are filtrated due to the formation of compressible filter cakes. READ MORE

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

    Author : Julie Durruty; Chalmers University of Technology; []
    Keywords : 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.

  5. 5. Pressure and Solidosity Profiles in Cake Filtration

    Author : Christian Johansson; Chalmers University of Technology; []
    Keywords : lignin; pressure and solidosity measurements; ethanol; constitutive relationships; solid-liquid separation; cake build-up;

    Abstract : Filtration is an important unit operation in theseparation of liquids from solids. The aim of this work was toinvestigate filtration properties of lignin sludge obtained in theproduction of fuel ethanol from spruce wood. READ MORE
