摘要： Electrodeionization apparatus and method. The electrodeionization apparatus includes an ion-depleting compartment in which alternating layers of an electroactive media are positioned. One of the alternating layers is doped to provide a more balanced current distribution through the apparatus. The method involves providing reducing the difference in conductivity between the alternating layers positioned in the ion-depleting compartment by adding a dopant material to one of the layers.

摘要： The present invention relates to a filter element having a non-porous extrusion laminated strip formed on at least one edge and at least one side of a membrane. The strip is used to provide a means for ensuring a good bond between the filter element and the material into which it is potted. The strip is formed by the use of one or more extrusion heads that apply molten or softened polymer to one or both of the surfaces of the filter in a width and height desired. The strip is then subjected to pressure such as through a nip to at least partially embed the polymer strip into the filter pores so as to create a strong mechanical bond between the strip and the filter element. Additionally, it allows for the simultaneous formation of more than one membrane with the edge lamination at the same time.

摘要： An electrodeionization (EDI) module is formed an anode spaced apart from a cathode, one or more waste channels formed between the electrodes and a product channel located inward of the waste channel(s). Ion permeable membranes form the boundary between the product channel and the waste channel(s). The product channel and waste channels are filled with a mixture of anionic and cationic ion exchange materials. At least the waste channel(s) and preferably the product channel as well, use either an anion bead having a relatively low affinity for the selected anion specie(s) to be retained (e.g. Type II) or it is a blend with Type I materials. Preferably, the membranes contain an ion exchange material to speed the transfer of ions across them. More preferably, the anionic membrane contains anion materials that have a relatively low affinity for the selected specie or species for retention.

摘要： 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 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 purified liquid mixtures. 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.

摘要： The water flux of UF and MF membranes is dramatically increased by treatment with an aqueous solution of an organic linear polymer without detrimental decrease in other characteristics of the membrane, e.g. solute-rejection. Particular candidates for such treatment include UF and MF membranes made of PS, PES, PAN, and PVDF. The dramatic effectiveness of treatment with aqueous solutions of PEG having molecular weights between about 2000 and 6000 Daltons is shown.

摘要： This invention provides a process for making microporous membranes from a polymer solution and the membranes therefrom. A thermal assist, such as heating of the polymer solution can be effected subsequent to shaping the solution, such as by forming a film, tube or hollow fiber of the solution under conditions that do not cause phase separation.. In a preferred embodiment, the formed solution is briefly heated to generate a temperature gradient through the body of the formed solution. The polymer in solution then is precipitated to form a microporous structure. The formation of a wide variety of symmetric and asymmetric structures can be obtained using this process. Higher temperatures and/or longer heating times effected during the heating step result in larger pore sizes and different pore gradients in the final membrane product.
