# Transport and Cation Exchange

Project file on GitLab

## Overview

This benchmark simulates the chemical composition of the effluent from a column containing a cation exchanger (Example 11 in the PHREEQC 3 documentation). The following setup is used for the simulation:

Full details of the model setup and parameters are given in the PHREEQC3 example (consulted MAY-2021):

The benchmark uses the ComponentTransport process in OGS-6 coupled with the IPhreeqc software (Parkhurst and Appelo,2013). The results show good agreement between codes. More details about the implementation of the ComponentTransport process in OGS-6 can be found in HC-Process.pdf.
