Solid-liquid separation can be expected to be a key operation in future biorefineries aimed at production of materials. The separation will likely become a significant challenge as many organic materials tend to form compressible filter cakes and many of the expected products have high specific surface areas. Developing methods for improving filtration processes will therefore be of importance.
One technique that could have the potential to improve solid-liquid separation is electro-assisted filtration. This technique makes use of the particles surface charge and has the potential to affect the filter cake formation though electrophoresis as well as achieving an additional driving force for solid-liquid separation through electroosmosis.
This work studies how electro-assisted filtration of microcrystalline cellulose at constant applied pressure and voltage is influenced by the surface structure of the solid particles....
