Designed by the Hydrogeology Group - Department of Geotechnical Engineering of the UPC. ETP calculation and calculation of balances of water on the floor.
BrineMIX seeks to create a Graphical User Interface (GUI) that automatically generates the input and reads the output of PHREEQC for a specific water mixing analysis. In the input only the chemical water samples, the mixing percentage and the mineral selection are set, whereas the output shows the chemical composition of the final water and its chemical precipitates. The purpose of this new program is to simplify a specific PHREEQC analysis for the user who does not usually work with it.
The GUI is a spreadsheet with locked cells, form controls, cell conditionals and some buttons to activate the macros. The input is restricted to 5 samples with 8 different chemical species, density and temperature. When the “RUN” button is activated, the input file is created and exported (ERUN), and PHREEQC is automatically opened with the generated input file already loaded. The macro remains in standby till the end of the PHREEQC analysis and subsequently the output file is imported and displayed to the user. The whole process takes less than 5 seconds.
