An apparatus and system of operation of an electrodialysis membrane and gask et stack for separation of components in liquid mixtures is disclosed. The syst em of operation for purification and deionizing liquids (108) includes an operation of pretreatment (112) by filtration for removal of inorganic contaminants, includes an operation of adsorption (116, 118) for removing organic contaminants by activated carbon adsorption, and includes an operati on of deionizing (122) for removing ions from the effluent liquids. The deionizing operation includes an apparatus having an electrodialysis stack (12) of a plurality of ion exchange membranes (42, 50, 58, 66) and separatin g gaskets (22, 30, 44, 52, 60, 36, 24) for selectively removing contaminant ions. The electrodialysis stack of ion exchange membranes and separating gaskets provides continuous operations for purifying ethylene glycol and glycol/water mixtures, for continuous desalinating of water, and/or for continuous deionizing of water to generate ultra-pure water or other purifie d liquid mixtures. The combination of treatment operations and the deionizing operation provides a continuous operating system with minimized down-time an d improved efficiencies over prior methods for purification of liquid mixtures .
