| Description
| - Whey contains more than the half of the solids of the original whole milk, including whey protein and most of lactose, minerals and water soluble vitamins. However, it is still often considered as a waste product of the dairy industry. Membrane separations can be applied in order to fractionate, purify, and concentrate whey components. The influences of process conditions during nano- and ultrafiltration (pH, temperature, pressure, composition, membrane type) on filtration kinetics, rejection and product quality (content of lactose, ions, proteins) were observed during filtration of three different types of filtration media (natural whey, model whey, dried sweet whey). All ultrafiltrations were carried out on ceramic tubular membranes (Membralox, Pall; cut-off 500, 200, 100 nm and 5 kDa) in one or multiple step ultrafiltration. Obtained permeates and/or model solutions were purified by nanofiltration on three types of polymeric membranes; Desal DL (GE Osmonics), NF-245 (Dow Chemical Company) and TFC-100 (Koch). Achieved mass concentration factors for UF were between 2.2 and 7 and this results support possible industrial applications. The slowest UF was the fine filtration on 5kDa membrane. The UF on a membrane with higher cut-off (100 - 500 nm) provided permeate fluxes between 20 and 200 l/h.m2.bar. Nanofiltration experiments confirmed high sensitivity of separation efficiency and kinetics on applied conditions, namely pH and solution composition. Desal DL membrane was more sensitive to the pH of feed than other two membranes. The membrane NF 245 is less dependent on pH and more suitable for separation of lactose from whey giving high lactose rejection (over 99 %) while the rejection of ions was significantly lower.
