A-Lima - Microfiltration Membranes

• in microfiltration membranes the pores are so big that they reject the colloids, suspensions and bacteria but the dissolved substances pass the membrane pores – ions and non-ionic chemical substances, for example vitamins or dissolved proteins
• the microfiltration process is based on that the product passes the membrane, for example milk goes through the porous ceramic membranes. The milk filtration on these membranes allow to reject bacteria and other microorganisms, spores and dead cells up to 99,5 – 99,9 %.

Beer production
The purpose to use a microfiltration is to sterilize a culture medium and beer. In brewery a microfiltration is used instead of pasteurization. Thorough this process this is possible to produce non-pasteurized beer with long expiry date, even a few months.                

Instead of centrifugal separation and sedimentation
Microfiltration gives an opportunity of sterile milk and cheese brine filtration, and purification of the solutions from suspended solids. This is an alternative for such technologies like centrifugal separation and sedimentation. The final result of microfiltration is, for example pasteurized milk with properties similar to a cow milk.
