1. On the local properties of compressible filter cakes
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
2. Displacement Washing in the Sulfate Pulp Mill
Sammanfattning : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. LÄS MER
3. Filtration of Microcrystalline Cellulose: Electro-assisted filtration and the influence of surface properties
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
4. Investigation of hard-to-filter materials -Relating local filtration properties to particle interaction
Sammanfattning : Filtration as a means of separating solids from liquids is an important unit operation employedin a range of different industrial sectors, e.g. forest products, mineral, chemical process andpharmaceutical industries to name but a few. LÄS MER
5. The influence of particle properties on cake filtration: Surface structure and surface charge
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
