    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Filtration of Microcrystalline and Microfibrillated Cellulose: The impact of ions and electric field

    Författare :Anna Hjorth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfibrillated cellulose; microcrystalline cellulose; ions; filtration; electro-assisted;

    Sammanfattning : Dewatering plays an essential role in the processing of microcrystalline cellulose (MCC) and microfibrillated cellulose (MFC), as their commercial attractiveness in many applications is limited by the high water content of the products. Filtration is the most common mechanical dewatering technique, but the filtration of these materials results in filter cakes with high filtration resistance. LÄS MER

  4. 3. Filtration of Cellulosic material - the impact of ionic strength and electric field

    Författare :Anna Lidén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-assisted; microfibrillated cellulose; ionic strength; microcrystalline cellulose; dead-end filtration;

    Sammanfattning : It is crucial that dewatering technology is considered if an economically feasible production of cellulosic materials is to be achieved. Cellulosic materials are often produced in dilute streams and therefore require great amounts of water to be removed to allow for reasonable transportation costs and/or further modifications. LÄS MER
