Simple Mixing Chemistry Equilibria Using Lookup Tables
Using Lookup Tables to Link to PHREEQC
One of most common application of geochemical models is prediction of the effects of mixing solutions of different chemical compositions. This model is an example of how to incorporate PHREEQC geochemical calculations into a GoldSim model through the use of a "Lookup Table" element. In this approach, the Lookup Table element is constructed using water quality results from a series of PHREEQC model runs that encompass the range of compositions that might occur in the system.
