Abstract: The present invention discloses a turn-back electrodeionization apparatus in which the central section of cation exchange membrane and anion exchange membrane constituting a dilute chamber is adhered along axial direction, and the dilute chamber is separated into an inner side dilute chamber unit and an outside dilute chamber unit, so that the dilute sequentially flows through the outside dilute chamber unit and inner side dilute chamber unit in a turn-back way.

Abstract: A stabilizing DC current interface for an electro-deionization (EDI) water purifying module. Each EDI module comprises anionic/cationic membranes, a center pipe, nets/spacers in concentrate/dilute water chambers and an anode and cathode for coupling to the stabilizing DC current interface. Because a stabilized DC current is provided by the interface, the power to each EDI module is not influenced by water temperature, flow rate, water quality in the module, thereby providing a stabilized quality product water while saving energy. A plurality of EDI modules can be operated in electrical series using a DC current interface resulting in reduced DC power consumption.

Abstract: The resin seepage-proof spiral would Electrodeionization (EDI) module includes anion and cation ion exchange membranes, concentrate and dilute distributing channels, net sheets inside of the channels, positive and negative electrodes and an EDI housing. The housing includes an insulation shell and covers. The multiple layers of anion and cation ion exchange membranes concentrate and dilute water distributing channels and net sheets are wound around a negative electrode pipe centered in the EDI module. The negative electrode pipe is arranged to collect concentrate water inside of the pipe. A circularity positive electrode is located outside the wound membranes and within the insulation shell, which is generally cylindrical in shape. Inside the cylindrical housing, the dilute water distributing channel is filled by ion exchange resin. The EDI module includes two inserts of multiple holed material layer, one on each end of the module.

Abstract: The dilute support frame is made up of interphase longitude and latitude bars that preferably are hollow. The bars can be rectangular, rectangular with a rounded end, half-circular, triangular, polygonal or any combination thereof. The bars are sized to support the ion exchange resin in the dilute channel adjacent the concentrate membrane bag. The support frame also assures fluent water flow in the dilute channel. The support frames are arrayed on the membranes with interphase aisle to save the frame arrays and make water flow fluently. The membrane envelopes in turn with the support frames as both are preferably wound to form the cylinder module, and is covered by one plastic protecting net. This new type of support frame can assure fluent water flow in dilute channels and convenient resin filling.

Abstract: An EDI device includes a composite electrode enclosed within the cylinder shell of the device. The EDI inner module preferably has one concentrate center pipe as the electrode in the center axis and at least one layer of anion/cation exchange membranes and a support frame in concentrate/dilute chambers wound around the center pipe. The electrode plate is inside the encircled cylindrical shell (isolating vessel). It is connected to an electrical contact plate located in the shell. Either the anode or cathode can be set in the center pipe, and the other electrode can be set in the vessel or shell lining. The electrical contact plate also contacts an electrical contact reed located on the vessel cover when the cover is connected to the shell. The electrical contact plate provides a reliable conductive bridge between the contact reed and the electrode plate and thus passes DC from the contact reed to the electrode plate.

Abstract: A replaceable spiral wound membrane element can be inserted and removed from its housing or pressure vessel in one piece for servicing or replacement. The replaceable wound membrane element preferably includes a concentrate pipe connected to spacers and membranes that are wound around the concentrate pipe to form a spiral membrane element. After the replaceable membrane element is placed inside its housing, its dilute spacers are filled with ion exchange resin and the housing is sealed to form an electrodeionization (EDI) module.

Abstract: The major component of the carbonate fraction of free acids extractable from alfalfa has shown excellent control of symptoms in patients with sickle cell disease. Its structure has been established by proton NMR spectrometry as being 16-hydroxy-9Z,12Z,14E-octadecatrienoic acid and closely related compounds, such as simple esters, amides, triglycerides, or other derivatives of the carboxylic acid function, and a method for its synthesis from linseed oil or methyl linolenate has been developed. The product from linseed oil, both in the form of the initially formed triglyceride and in the form of its free acid obtained by saponification, is useful for the treatment of sickle cell disease.

Abstract: A laser recording medium in which the metal recording layer is completely encapsulated between an intermediate layer of solvent resistant plastic material formed on a substrate and a protective layer of solvent-based plastic material formed on the recording layer. In some examples the solvent resistant plastic material is a cross-linked polymeric material formed in a solvent coating process and in other examples the solvent resistant plastic material is a vapor deposited polymeric material.

Abstract: A helical electrodeionization apparatus is adapted to purify aqueous liquids to effect the production of high purity water. An insulated net-separating wall is positioned between a pair of anion and cation exchange membranes to form a special membrane bag type flow unit I, each flow unit I is linked up with a group of slots on the side walls of central pipe, and is rolled up to form cylinder structure which centers on central pipe as the helical axis, a conductive crust is formed by winding metal strip or wire outside the cylinder. Ion exchange resin is filled up between the adjacent membrane bags to form flow unit II. The present invention has less pressure drop and needs less power, and is suited to multiple-device series operation. Preferably, daily maintenance and renewal of the resin is convenient, and production cost is lower.
