Ion exchange calculator

This calculator is under construction

This calculator helps you with the design of a ion exchange installation. The calculator is based on the following process:

The calculations are made using theoretical equations. As a consequence this calculator ONLY gives you an indication about the different parameters that are necessary to design an Ion Exchange water treatment installation.

Input fields marked with * are required to give good calculated values.
