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 et al. 2013). The results show good agreement between codes. More details about the implementation of the
ComponentTransport process in OGS-6 can be found in
