This is a filtration on porous membranes with relatively big pore size of  0,2 – 10 microns, low pressure of  0,1 – 0,3 МPа and high flux from few up to more than ten  m3/(m2*hour).


  • 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 %.
