Air and Gases Sterile Filtration

There is generally a high risk of microbial contamination during technological operations due to the favourable conditions for microbial growth – higher temperature and the presence of moisture.

This risk presents a concern if the beer , for example, is cold stabilized by microfiltration, so the packaging operation must be aseptic and the microbial hazards adequately controlled. To minimise the risk of microbial contamination and to achieve stable beer once packaged, it is essential that any compressed air or gas used during all related technological points must be sterilized effectively

When some pre-treatment of compressed air/gases is needed we recommend to install sufficient pre-treatment like dyers range Polestar or Starlette and effective prefiltration stages.
