Sažetak

The influence of ultrafiltered whey characteristics (sweet, acid) on the permeate flux during the microfiltration was studied using membrane type GRM 2,0 PP. General parameters as well as bacteriological quality of all samples were determined. The results indicated microfiltration of acid ultrafiltered whey as better process owing to the fact that the retention of proteins was minimum and permeate flux good. Also, whey and permeate compositions were changing. Permeate contained more lactose than protein. The results indicated that membranes type GRM 2,0 PP can eliminate from UF-whey 97,4% of viable bacteria. This type of membranes completely retained merely yeasts and moulds.
