Media Ion Exchange

bio isolates Cellulose Ion Exchange Resins logo




Cellulose ion exchange resins are used across most sectors and specifically to produce dairy, baby food, performance food supplements and food intolerance products, utilising an adsorption process for applications such as:

  • Selective, high purity extraction of specific, undenatured, functional proteins and enzymes from food waste streams such as cheese whey and abattoir waste.
  • Water softening, removing calcium and other salts from water to suit chemical industries and improve potable water.
  • Waste flocculation and removal, removing heavy metals and impurities from process streams.

Media is the support structure of a resin, with a functional group still being required. However the support structure influences the specific binding capacity, stability, active surface area and resolution of the adsorption process.

Benefits OF MEDIA

Using media as the support structure of your resin facilitates the adsorption of many adsorbents, from large macromolecules like enzymes and proteins, to the removal of salts.


  • Chemically stable at high pressure
  • Thermally stable up to 282°C
  • High particle Integrity
  • High selectivity in water based solutions
  • Swelling increases active surface area
  • High surface area per kilo of media
