BloX20 EDI modules
BloX20 EDI modules are electrodeionization (EDI) modules which use electrical current to deionize and polish reverse osmosis (RO) permeate water. The product water for the BloX20 modules is at an Ultrapure level required in today’s demanding applications.
Features
- Firstly, provide ultrapure water for industrial applications on a continuous basis using proven electrodeionization technology.
- Secondly, nominal flow of 20 m3/h for each BloX results in the most compact footprint in industry.
- Thirdly, modular design of the DeionX BloX is ideal to easily design an EDI system for practical unlimited flows by coupling several individual DeionX BloX.
- Next, non-corrosive design by use of high quality (construction) plastics only.
- Lastly, designed to minimize and simplify local installation.
