The Principle

Ion Exchangers are insoluble granular substances which have in their molecular structure acidic or basic radicals that can exchange. The positive or negative ions fixed on these radicals are replaced by ions of the same sign in solution in the liquid in contact with them The ion exchange is complete without deterioration or solubilization nor changing the total number of ions in the liquid before the exchange.

The ion exchange substances are used almost exclusively under the name of resins. There are two categories of it: the resins of the gel type and those of the macro porous or loosely cross-linked type. Their basic structure is identical: the macromolecular structure is obtained in both cases by copolymerization. The difference between them lies in their porosity.

• Efficient

because of modular design and low internal water consumption

• Full automatic

controlled by high sophisticated process measurement

• Flexible

by using a local PLC or fully integrated in the overall process
