Membrane Modules with a Sanitary Design for Increased Product Quality and Sustainable Production Processes in the Food Industry.

In the food and beverage industry, membrane technology is becoming increasingly important for the manufacture of high-quality products. Membrane modules with a sanitary design and high thermal and chemical resistance are indispensable for use in the F&B industry. Membrane technology is used to separate, concentrate and fractionate ingredients, enabling a wide range of different, high-quality products or extending the shelf life of foods. Membrane systems also support sustainable production by purifying water or treating wastewater efficiently, thus minimizing the industry’s ecological footprint.  

Applications in Food Technology

  • Vinegar filtration (from fermentation)
  • Production of flavors and ingredients
  • Clarification of fish brine
  • Production of fresh cheese
  • Filtration of marinades
  • Clarification of juices and wine
  • Clarification of citrus fruit juices
  • Processing of caustic soda
  • Processing of whey concentrate
  • Filtration and treatment of brine
  • Concentration of liquid egg and gelatine
  • Ultrafiltration of whey protein isolate

Membrane Separation Technology in Food Technology

Various membrane processes are used in the dairy industry, the largest F&B market with a long history of membrane usage. For example, reverse osmosis and nanofiltration are used to concentrate and demineralize milk, whey and lactose.


Ultrafiltration modules concentrate whey, a by-product of cheese and casein production, to produce whey protein concentrate (WPC) or whey protein isolate (WPI). Microfiltration modules are used to degrease whey, which improves the quality of whey protein concentrates and isolates. Membrane separation technology has established itself as an indispensable component of many F&B processes, with spiral wound modules accounting for the dominant share.


WTA UNISOL offers its customers in the food sector a versatile range of sanitary designs as well as membranes and modules for microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Our products are characterized by high product quality, precise cutt-offs and the use of FDA and EU-compliant materials.

As a competent partner in the food & beverage sector, we offer you a wide range of membranes, formats, spiral wound modules, DT modules and submerged membrane units from our portfolio.


With the acquisition of AMS in March 2023, WTA UNISOL is now also able to supply the AMS NanoPro and UltraPro series, which are resistant to alkalis, acids and solvents.
