Liqui-Flux^® Beverage Modules - Economical Reliability in Microfiltration!Liqui-Flux Microfiltration Membrane Modules used in beverage clarification have a high throughput and superior performance. The key success factors in the clarification of wine are the membrane selection with regard to fouling behavior and the proper module design for superior filtration performance. Membrana offers both to its customers.Accurel^® Polypropylene Membrane Fibers – Superior Permeability!Accurel PP hollow fiber membranes feature a symmetric pore structure and high specific surface area. This in combination with the excellent low adsorption characteristic of the pure polypropylene polymer, supports Accurel PP membranes as a reliable and economical alternative to conventional separation procedures used in beverage clarification today. Moreover they provide superior filtration performance when compared to other membranes based on polyarylsulfone.


Membrana manufactures a dedicated membrane portfolio based on polypropylene to provide the required performance in the various beverage clarification processes. With different nominal pore-sizes and inner diameters, Membrana can build tailor made beverage filtration modules for specific end uses and applications. Since polypropylene membranes are hydrophobic by nature, all Liqui-Flux microfiltration membrane modules are delivered hydrophilized for immediate use.
