Summary:Whey can be used as a raw material and provide new potential for the industry because of the properties of its components. Electrodialysis has been used to demineralize solutions, thus separating nutrients. In the present paper, experiments are presented for the demineralization of whey permeate through electrodialysis to obtain a stream of purified lactose. Compartments consisting of various electrode solutions were tested sodium chloride, calcium chloride, potassium chloride, and potassium sulfate with electrical conductivities of 6 mS · cm −1 . The most efficient solution was potassium sulfate, which promoted the purification of lactose solutions while showing good prospects for future manufacturing conditions.
