摘要： An ion-exchange membrane is disclosed here including ion-permeable layers impregnated with an ion-exchange material and arranged in an order from one face of the membrane to the opposite face of the membrane such that opposing layers in the supporting membrane substrate provide sufficiently identical physical properties to substantially avoid irregular expansion when in a salt solution. The ion-permeable layers including at least one non-woven layer and at least one reinforcing layer.

摘要： An electrodialysis cell includes a housing defining an internal chamber, a core positioned within the internal chamber, a first electrode positioned in the internal chamber adjacent the housing, a second electrode coupled to the core and spaced from the first electrode, and a membrane assembly positioned between the first and second electrodes in a spiral wound configuration. The housing includes an inlet end for receiving a feed fluid and an outlet end in fluid communication with the inlet end. The membrane assembly includes a plurality of ion exchange membranes spaced from each other to define a plurality of fluid channels between the inlet and outlet ends.

摘要： An ion exchange membrane and a method of making it. The membrane may be used, for example, in an electrodialysis module or electrochemical cell. The membrane comprises an ion exchange polymer and inorganic particles preferably linked to the ion exchange polymer. To make a membrane, inorganic particles are mixed into an ion exchange membrane pre-cursor. A polymerization initiator or catalyst is then added and the resulting mixture is placed in a form and cured. The inorganic particles may comprise, for example, an oxidized form of graphite such as graphite oxide. The ion exchange polymer may comprise an ionic monomer, containing a quaternary ammonium group for anion exchange or a sulfonate group for cation exchange, along with a crosslinking co-monomer containing polymerizable diacrylic functionalities. The membrane is self-supporting and can be made without a supporting fabric.

摘要： A bipolar membrane electrodialysis method and system are described for purifying an organic acid from an aqueous solution containing the salt of the organic acid. The system includes a bipolar membrane electrodialysis stack that includes at least one three-compartment bipolar membrane electrodialysis cell and at least one two-compartment bipolar membrane electrodialysis cell. The method includes recirculating the solution of organic acid produced from the three-compartment bipolar membrane electrodialysis cell and two-compartment bipolar membrane electrodialysis cell. Cation or anion exchange resins may be included in the spacers of acid compartment to increase the conductivity of acid compartments, thereby increasing current density of the bipolar electrodialysis stack and decreasing power consumption.
