Abstract
An apparatus and system of operation of an electrodialysis membrane and gasket stack for separation of components in liquid mixtures is disclosed. The system of operation for purification and deionizing liquids includes an operation of pretreatment by filtration for removal of inorganic contaminants, includes an operation of adsorption for removing organic contaminants by activated carbon adsorption, and includes an operation of deionizing for removing ions from the effluent liquids. The deionizing operation includes an apparatus having an electrodialysis stack of a plurality of ion exchange membranes and separating gaskets for selectively removing contaminant ions. The combination of treatment operations and the deionizing operation provides a continuous operating system with minimized down-time and improved efficiencies over prior methods for purification of liquid mixtures.
