Membrane types

The heart in any membrane filtration process is the membrane itself, and choosing the best membrane for a given process is often a difficult task. Membrane type, plant design and processing parameters should be carefully matched to meet the desired performance and cost-efficiency of the overall process. 

Tetra Pak Filtration Solutions is one of the world's largest providers of membranes for dairy applications, and we offer supply and replacement of polymer spiral-wound, plate & frame, as well as ceramic membranes and all types of spare parts for membrane filtration systems.

Typical applications of polymer and ceramic membranes

Membrane material Type Typical applications
Polymer Spiral-wound Skyr, Greek yoghurt, quark, fromaige frais
Polymer  Plate & Frame Cream cheese, Baker's cheese
Ceramic Tubular ESL milk, Greek yoghurt, dairy-based ingredients

Polymer spiral-wound

sw module

Features

The SW membrane element is a unique design, where a large membrane area is wound into a compact element. A number of membrane elements are fitted into a stainless steel housing to form a module, and a number of modules are built into a plant.

Benefits

  • Low cost
  • Compact design
  • Cost-effective processing economy
  • Offers a wide range of applications for the dairy industry  

Polymer plate & frame

plate frame

Features

In Plate & Frame systems, membranes are laid on top of a plate-like structure, which in turn are mounted on PSO support plates. Used for UF of highly viscous products.

Benefits

  • Handles high viscosity products
  • Highly defined flow dynamics
  • High temperature resistance
  • Possibility of isolation of individual membranes
  • High configuration versatility 

Ceramic tubular

tubular ceramic

Features

  • Ceramic membrane and support structure
  • Specific accurate pore size
  • 3 and 4 mm  diameter flow channels

Benefits

  • Chemical and temperature resistant for easy CIP, excellent hygienic properties
  • Durable for long membrane life
  • Sanitizable
  • Defined flow conditions
