Eurodia Industrie is a dynamic and innovative French separation process company with over twelve years of experience in the design, construction, and operation of plants featuring:

    Electrodialysis with and without bipolar membranes

    Ion exclusion chromatography

    Microfiltration

    Nanofiltration

    Ion exchange resins.

    The principal mission of Eurodia Industrie is to select, evaluate, and apply a combination of processes to provide the best technical and economical solutions to its customer separation problems. Originally the company was a supplier of electrodialysis stacks and systems. Its "savoir faire" has demonstrated that, in many cases, the optimum process is found by combining several technologies. This approach has resulted in dozens of successfully operating plants with more than one process step provided by Eurodia and in an equal number of satisfied customers.

    Ameridia was established in 1999 as the branch office for North and South America. The main shareholder of Eurodia Industrie is Tokuyama Corporation, a major Japanese chemical company based in Shibuya, Tokyo.

    Electrodialysis:

    Eurodia has supplied over 40 electrodialysis plants for desalting or deashing applications in the dairy, sugar, starch, chemical, pharmaceutical, drinkable water, wine, etc. industries. Eurodia has developed its unique, high performance stack technology with a wide range of proprietary spacers featuring virtually no internal leaking, different thicknesses and materials (FDA approved grades), and netting materials to lower pressure drops. The stack design and the electrode selection allow for operation with and without current reversal.

    The extensive selection of NEOSEPTA?ion-exchange membranes used in the electrodialysis stacks are manufactured in Japan by Tokuyama Corporation. This family of long life membranes include several cation-exchange and anion-exchange membranes, as well as a bipolar membrane. Some of these membranes are food-grade, organic fouling-resistant, and allow for operation at temperatures up to 60篊. Monovalent anion- or cation-selective membranes and caustic-resistant membranes are also available for the development of interesting applications. Tokuyama Corporation has a dedicated group of scientists to develop new membranes and improve existing membranes to meet the application requirements

    Applications include demineralization of cheese whey, deashing of sugar juices, desalting of amino acids and other foodstuff, tartrate stabilization of wines, acid removal from organic solutions, nitrate removal in drinking water, brackish water desalination, etc.

    Eurodia also provides plants for electrodialysis with bipolar membranes (or "water splitting") used to convert aqueous salt streams into acids and bases, or to acidify / basify product streams without adding chemicals. The employees of Ameridia have also many years of experience in electrodialysis with bipolar membranes, for which several plants were put in operation when they were working for Aqualytics (Warren, NJ). One of the most attractive applications for water splitting is the production of organic or amino acids from their salts and the recovery of the base used in the fermentation or the chemical reaction.

    Ion Exclusion Chromatography:

    Eurodia Industrie is a licensee of the Nippon Rensui (Tokyo, Japan) Improved Simulated Moving Bed (ISMB) technology for the food, pharmaceutical, and fine chemical industries. The process features (1) a proprietary fluid distribution system, (2) resins of high quality and fineness supplied by Mitsubishi Chemical, and (3) the use of four chambers per column with a sequenced inlet/outlet arrangement. Thanks to these, it is possible to obtain high purities and up to 30% lower water consumption (and a correspondingly lower product dilution). More than 90 plants are in operation throughout the world for applications such as fructose/ glucose separation as well as the separation of polyols.

    Microfiltration:

    Eurodia Industrie supplies the Scepter? sintered steel membranes from Graver Technology (Glasgow, DE). These membranes can separate from 0.01 to 1.0 micron and offer major benefits such as high pressure (up to 70 bars) and high temperature (up to 180癈) operation, as well as large diameter tubes and cross-low design compatible with very viscous (up to 100's of centipoise) and complex mixtures of products (up to 50% suspended solids). Other features are high chemical resistance (from pH 0 to 14) and the ability to withstand the toughest cleaning with steam and other chemical sanitization, superior mechanical durability with gasket-free, all-welded construction, a small footprint requirement, and long service life of up to ten years, depending on the applications.

    Many systems are operating in the food/ starch/ sugar, textile, biotechnology, etc. industries in North America and the Far East. A first commercial plant will be commissioned by Eurodia Industrie this year in the European sugar industry.

    Nanofiltration:

    To provide optimized processes to customers in the dairy, food, sugar, etc. industries Eurodia Industrie also provides Nanofiltration modules and systems. A first system has been commissioned in early 2000 at a large European dairy with more than 300 m2 of membranes.
