CEDI-VNX-Module

The VNX module has been developed to reduce the costs for the construction of CEDI systems with high flow rates and provides a simple clean and environmentally sustainable technology in contrast to chemically regenerated mixed bed ion exchanger systems. Through this new and one-off technology the number of modules can be reduced whereby the pipe work and installation of the systems is simplified and therefore can be constructed more cheaply.

In both LX and VNX modules, the spacers are stacked in a conventional plate and frame construction, whereby the product and concentrate spacers are alternately arranged. This configuration offers more even distribution of the through and also the current flow than other configurations can (such as, for instance, spirally wound modules). This property is very important for the performance and durability of the module.
