Eurodia Industrie is a dynamic and innovative French separation
process company with over eighteen 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 more than 100 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 60ºC. 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°C) 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 system has been commissioned in early 2000 by Eurodia Industrie in the European sugar industry.
Nanofiltration
/ Ultrafiltration:
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 3 000 m2 of membranes. Since then several nanofiltration systems have been successfully commissioned.
Facilities:
For contact addresses, please go to the “Contact us” Section of this web.
The main facility of Eurodia Industrie is located in Pertuis 30 mn far from Marseille (Marignane) airport and 20 mn from TGV (Aix en Provence) station. The Company owns 2000 m2 building with its own corporate sales, engineering, and technical office, as well as a testing laboratory with several pilot units. The same building includes a large workshop where electrodialysis modules are refurbished, assembled, tested and shipped.
The head office is located at Rungis (Southern suburb of Paris) in the vicinity of Orly airport.
Ameridia, the American Branch Office, has leased a 500 m2 facility in Somerset, New Jersey (about 30 min from Newark Airport) to house its sales and engineering offices, spare parts inventory, as well as a workshop to refurbish and assemble electrodialysis modules.
In Japan, Tokuyama Corporation (the main shareholder of Eurodia) manufactures the ion exchange membranes at a plant that is part of its large industrial complex located in Tokuyama-city (Yamaguchi Prefecture, Southern Honshu). Electrodialysis modules are also assembled and refurbished in this facility Membrane and process development is done at a technical Center that will be moved from Tokuyama-city to outside of Tokyo this year. The sales office for the membrane business is located at the company’s Shibuya (Tokyo) headquarters.
