Özet
In this study, demineralization of cheese whey by sequential nanofiltration (NF) and electrodialysis (ED) methods was investigated. For the NF step, two NF membranes labeled as NF-270 and NF-90 were tested. Approximately 90% of protein and lactose rejections were obtained with partial demineralization during NF step. For full demineralization of the NF permeate, NF followed by ED process. Two different ED systems (Tokuyama TS-1-10 with Neosepta membranes and Mega EDZ-10x4-0.8 with Ralex membranes) were used. The rejections of Na+, K+, Ca2+, and Mg2+ ions from the NF permeate with Ralex membranes were calculated as 82.5%, 99.3%, 87.9%, and 92.9%, while the corresponding values were 80.2%, 99.0%, 95.6%, and 100% by Neosepta membranes, respectively. © 2019 MPRL.
