1. Molecular filtration : the study of adsorbents
Sammanfattning : Adsorbent materials for gas purification have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Therefore, the development of adsorbent materials has accelerated over the past two decades, and is today an area attracting a lot of attention. LÄS MER
2. 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
3. Mathematical and Experimental Study on Filtration of Solid Inclusions from Molten Aluminium and Steel
Sammanfattning : Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes.

4. Lignin Extraction from Black Liquor - Precipitation, filtration and washing
Sammanfattning : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. LÄS MER
5. Lignin Exraction from Black Liquor: Precipitation, filtration and washing
Sammanfattning : Lignin extraction is a very interesting option for pulp mills today. Lignin is one major component, present as a dissolved organic compound, in black liquor, which is a by-product in the alkaline pulping of wood. After the digestion of wood chips, the black liquor is separated from the cellulose. LÄS MER
