Lenntech Electrodeionization Ionpure (EDI) modules

Evoqua / Ionpure, EDI modules
VNX Modules
The VNX module was developed to reduce the cost of building high flow rate CEDI systems and to make it easy to choose a clean, environmentally compatible technology over chemically regenerated mixed bed ion exchange systems. Higher flow rate CEDI modules result in easier piping and system assembly by reducing the number of modules required.
VNX modules have a build-in support system. This allows for smart skid design and minimal skid cost.

LX Modules
The Ionpure LX modules are specifically designed for industrial applications. Ionpure modules consistently deliver maximum reliability and superior performance for power, HPI/CPI, general electronics, food and beverage and laboratory applications without regeneration downtime.
In order to cover a wide range of product applications, The LX series have several options:
LX-Z modules have PVC spacers, they are ideal when no FDA approval is needed but high quality water is still required.
LX-X modules have no PVC parts so design for more critical applications.
LX-HI modules can be sanitized with hot water, a perfect solution for high end applications in Pharmaceutical, Biotechnology and Food & Beverage industries
LX-MK modules can be used to retrofit E-cell-MK EDI units

MX Modules
The Ionpure MX Series CEDI modules deliver superior performance for laboratory and lower flow process applications. MX modules are an ideal complement for light industrial, commercial & laboratory RO systems that are wall mounted or housed in a cabinet.
Electrodeionization is a water treatment technology that utilizes a electricity, ion exchange membranes and resin to deionize water and separate dissolved ions (impurities) from water. It differs from other water purification technologies in that it is done without the use of chemical treatments and is usually a polishing treatment to reverse osmosis (RO). There are also EDI units that are often referred to as Continuous electrodeionization (CEDI) since the electric current regenerates the resin mass continuously. CEDI technique can achieve very high purity, with conductivity below 0.1 µS/cm.

Very good explanation, how much dc voltage needed for certain distance anode catode? Thank
