PHREEQC Version 3

Overview of PHREEQC Version 3

Sources/Usage: Public Domain.

PHREEQC Version 3 is a computer program written in the C++ programming language that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC implements several types of aqueous models including two ion-association aqueous models.

Features

•  Version 3.0--Documentation of all features, including high pressure calculations, charting (Windows), Pitzer and SIT activity-coefficient models, CD-MUSIC surface complexation, and isotope capabilities. Updated PhreeqcI. Additional methods for IPhreeqc modules.

•  PhreeqcRM--Reaction module for reactive-transport simulators. Based on IPhreeqc, allows access to all PHREEQC reaction capabilities. Contains methods for initial and boundary conditions, running reactions on all model cells, transfer of data to and from the module, and parallelization by MPI or OpenMP.
