Abstract
An electrodialysis treatment system utilizing a plurality of disparate layers of an electrodialysis cell stack for separation of components in liquid mixtures. The system for electrodialysis treatment for purification and deionizing liquids includes providing an operation of pretreatment by filtration for removal of inorganic and organic contaminants and generating a filtrate effluent. An adsorbing operation for adsorbing organic contaminants from the filtrate effluent of the pretreatment operation is provided by utilizing activated carbon adsorption and generating a liquid fraction. A deionizing operation for continuously purifying the liquid fraction is provided by utilizing an electrodialysis stack having a plurality of ion exchange membranes and separating gaskets for selectively removing contaminant ions from the liquid fraction of the adsorbing operation. The deionizing operation provides continuous purifying and deionizing of the liquid fraction to generate ultra-pure water or other purified liquid mixtures.
