Evaluation of the electrodialytic whey desalination effectivity at different temperatures

Original language description

Sweet whey, which is a by-product of the production of hard and semi-hard cheeses, is one of the most important sources of lactose, calcium, proteins, and soluble vitamins, making it an important source of valuable nutrients for food applications.In the production of cheese, whey is formed in an amount of about 9:1 in relation to the main product. Due to the large volume of production, the question of whey processing and further use is acute. Previously, whey had no nutritional value due to the lack of worked-out processes of its processing, in connection with which it was disposed by discharging into wastewater. The main problem for whey application is the high content of mineral salts as well as organic acids, which leads to a salty taste of the final product and difficulties in further processing. The high salts and organic acids of whey content are solved by partial demineralization. For demineralization processes such as nanofiltration (NF), ion exchange (IEX), electrodialysis (ED) are most widely used. The demineralization of sweet whey in the ED process occurs through the transfer of ions in solution through several pairs of semipermeable anion- and cation-exchange membranes containing charged functional groups under the action of an electric potential difference. As a result of the ED, there is almost complete removal of monovalent ions and a significant part of multivalent ions such as Ca2+, Mg2+, HxPO4(3-x), HxSO4(2-x) etc.
