|Completed by||Wageningen UR - FBR|
How does it work?
|Primary objective||Solid–liquid separation, solid-gas separation|
|Working principle|| Microfiltration is the process of filtration with a micron sized filter (Range 0.1 – 10 µm). The filters can be in a submerged configuration or a pressure vessel configuration (0.1 – 10 bar). They can be hollow fibers, flat sheet, tubular, spiral wound and hollow fine fiber. Filter materials are ceramic, textile, metal and polymer.|
|Additional effects|| Effect:
|Important process parameters||pressure, pore size, filter area|
|Important product parameters||viscosity|
What can it be used for?
|Products||Beverages, water treatment, suspension|
|Operations||Removal of selected particles from (large) streams (liquid or gas).|
|Solutions for short comings|| Potential needs:
What can it NOT be used for?
|Products||Dry powder, solids|
|Operations||Not to be used for nanofiltration, utrafiltration (smaller particle sizes), sterilistaion (depending on pore size)|
|Other limitations|| Other limitations:
|Risks or hazards||Aggressive chemicals can change the filter properties during process (e.g pore size, loading, ...)|
|Maturity||Available in lab-, pilot- and industrial scale.|
|Modularity /Implementation|| Modularity:
|Consumer aspects||Not known|
|Legal aspects||Not known|
|Environmental aspects||Use of water and cleaning detergents is very high.|
