Demineralization of natural sweet whey by electrodialysis at pilot-plant scale

Popis výsledku v původním jazyce

Demineralization of sweet whey was performed in a pilot electrodialysis unit EWDU-P1 provided with EDR stack with 50 membrane pairs of membranes RALEX CMH-PES and AMH-PES. Experiments were carried out at 15 ?C in batch operation mode. Constant outer voltage was kept. The influence of different outer voltage and spacer thickness on the velocity of salt transport and energy consumption was studied. At higher outer voltage 90 % demineralization was reached earlier, but energy consumption increased too. Thespacer thickness did not have significant effect on the length of the process and energy consumption. The transport of individual salts and losses of organic components were studied too. Removal of chloride (up to 99 %) and potassium (95 %) was the mosteffective; the lowest cut appeared for magnesium (75 %) and calcium (80 %). Losses of lactose were negligible; decrease of crude protein content was maximally 5 %. Decrease of titratable acidity was observed too.
