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

    Författare :Jonas Wetterling; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface structure; electrostatic particle interactions; cake filtration; solid-liquid separation; compressible filter cake; local filtration properties;

    Sammanfattning : 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. LÄS MER

  7. 5. On the local properties of compressible filter cakes

    Författare :Tuve Mattsson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
