Removal of biofilms formed on ion-exchange membranes in ultrafiltration permeates of secondary dairy raw materials

The modelling of biofilm development on MK-40 and MA-41Π ion-exchange membrane coupons was conducted in skim milk, sweet whey and acid whey ultrafiltration permeates. The membranes were suspended in permeates for up to five days at the room temperature. The incubation was followed with cleaning proc...
