原始语种摘要: Abstract(#br)The neutralization of milk whey after the electrodialysis (ED) is usually carried out by direct addition of NaOH or KOH solution. However, the addition of these solutions results in an increase in total solids and ash content of the whey sample. In this work, electrodialysis with the bipolar membrane (EDBM) was examined to neutralize the desalinated whey after ED. First, ED was used to desalinate the nanofiltrated whey (NFW). Three milk whey samples differing in demineralization rate in ED were subjected to the EDBM. Two configurations of EDBM were applied to increase the pH of the milk whey samples. When the samples which had been demineralized first with conventional ED, were submitted in EDBM the pH increased to the desired values. However, the pH of NFW sample only...
