Solar cell manufacturing powers Ionpure VNX sales
With the ability to produce high-purity water at consistent quality without the need for chemical regeneration, Ionpure VNX continuous electro-deionisation (CEDI) is making an impact on the Ger-man solar cell industry. VNX modules are designed for use in semiconductor fabrication or wherever flows of above approximately 30m3/hr are required.
Two VNX-3 modules have recently been supplied to AW Abwasser-Wasser-Technik. Provided by Ionpure's distributor in the Netherlands, Pure Water Systems, they are installed in two purification systems, each producing 13.5m3/hr. They use ion-permeable membranes, ion exchange resins, and a DC electric potential, which drive the removal of ions from the feed stream while continuously regenerating the resins. This technology offers a clean, environmentally compatible alternative to a chemically regenerated, mixed bed ion exchange plant. Modules may be con-nected end-to-end or stacked using the Flexmount endblocks, which will reduce the cost associated with the piping and support structure of conventional CEDI systems. In addition, VNX improves on the company's LX technology, which uses a plate and frame configuration for enhanced flow distribution of both fluid and electrical current, rather than a spiral wound configuration, to produce superior performance and longevity. A double O-ring seal at each end of every module ensures leak-free service up to the 7 bar feed water pressure rating.
