Ionpure VNX

The VNX module uses a "round disc" design to reduce the cost of building high flow rate EDI systems and to make it easy to choose a clean, environmentally compatible technology over chemically regenerated mixed bed ion exchange systems. Higher flowrate EDI modules result in easier piping and system assembly by reducing the number of modules required.

In both the LX and VNX, the spacers are stacked up in a conventional plate-and-frame arrangement, with alternating product and reject compartments (see Exploded Views below). This configuration gives much more even distribution of both fluid flow and current flow than some other configurations, such as spiral wound. This is very important for both performance and module longevity

VNX28-EP and VNX55-EP Data Sheet

VNX-CDIT

Performance has been optimized for suitability on most single-pass reverse osmosis feed water. CDIT is designed for feed water up to 4 ppm of hardness, greatly widening the application window for EDI (Electrodeionization) technology.

  • Up to 4 ppm as CaCO3 hardness
  • Up to 2 ppm SiO2
  • Up to 100 microsiemens/cm inlet
  • Expanded CO2 capacity

VNX-E

>17.5 or 18 megohm-cm product quality guaranteed

  • 98.5-99% water recovery
  • 95% removal of boron and silica
  • 99.8% removal of sodium and chloride
  • No Concentrate Recirculation or Brine Injection

VNX-EX

>17.5 or 18 megohm-cm product quality guaranteed

  • 95-97.5% water recovery
  • 99% removal of boron and silica
  • 99.9+% removal of sodium and chloride
  • No Concentrate Recirculation or Brine Injection
