在实验室电渗析（艾德）装置中研究了合成超滤乳清渗透液和重构超滤乳清渗余物的脱矿作用。
在三种温度（20、35和45 ℃）和三种流速（100、160和230 l/h）下报告了关于电导率、离子浓度、灰分去除、电效率和能耗的数据。由于浓差极化，UF-乳清渗余物的脱灰程度低于UF-乳清渗透物，这导致边界层厚度的增加，这是由于蛋白质和盐在膜上的沉积。
Demineralization of a synthetic UF-whey permeate and a reconstituted UF-whey retentate was studied in a laboratory electrodialysis (ED) unit.
Data on conductivity, ionic concentration, ash removal, electrical efficiency and energy consumption are reported at three temperatures (20, 35 and 45C) and three flow rates (100, 160 and 230 l/h). the extent of deashing is lower for the UF-whey retentate than for the UF-whey permeate as a result of concentration polarization, which results in an increase of the boundary layer thickness, due to deposition of proteins and salts on the membranes.
