摘要：The recovery and purification of whey with the concentration, reincorporation and reuse Protein and Lactose were studied by coupling the two operations: Ultrafiltration with a ceramic membrane and the reverse osmosis with the organic membrane. The two operations were performed in batch mode. In the first step the ultrafiltration, was operated in one stage, and produced the best results from the point of treatment capacity and protein recovery. The ultrafiltration was concentrated the total solids and protein concentrations with around 60% of protein. In the second step the UF+RO combination produced the best results of COD; BOD 5 (99%) and a high concentration of the lactose with around 51% in a Volume Reduction Factor 3 (VRF3). The concentration of protein, lactose and reducing the organic load by ultrafiltration coupling with the reverse osmosis operations has zero discharge.
