Reverse Osmosis Scaling Software in Python (ROSSpy) <https://pypi.org/project/ROSSpy/> offers an open-source API to simulate the reactive transport geochemistry of Reverse Osmosis desalination. ROSSpy essentially translates user specifications of an RO system into PHREEQpy <https://pypi.org/project/phreeqpy/>, which is the Python version of PHREEQC <https://www.usgs.gov/software/phreeqc-version-3>_. The examples/scaling/scaling_validation directory of the ROSSpy GitHub <https://github.com/freiburgermsu/ROSSpy> details the numerous functions and accuracy of ROSSPy via Notebook examples. We encourage users and developers to critique and improve ROSSpy, as an open-source (MIT License <https://opensource.org/licenses/MIT>) library, through GitHub issues <https://github.com/freiburgermsu/ROSSpy/issues>_.
The complete documentation is provided by ReadTheDocs <https://rosspy.readthedocs.io/en/latest/index.html>_.
++++++++++++++++++++++ Installation ++++++++++++++++++++++
ROSSpy is installed in a command prompt, Powershell, Terminal, or Anaconda Command Prompt via pip::
pip install rosspy
The IPHREEQC module must then be installed, since this is the source of geochemical calculations and data for ROSSpy. The appropriate version of IPHREEQC can be installed from the USGS <https://water.usgs.gov/water-resources/software/PHREEQC/index.html>_ .
Linux installation may require addition steps (Ubuntu < 20 is currently unsupported)::
wget https://water.usgs.gov/water-resources/software/PHREEQC/iphreeqc-3.7.3-15968.tar.gz
tar -xzvf iphreeqc-3.7.3-15968.tar.gz
cd iphreeqc-3.7.3-15968
./configure
make
make check
sudo make install
pip show phreeqpy
mkdir -p /path/to/site-packages/phreeqpy/iphreeqc
sudo cp /usr/local/lib/libiphreeqc.so /path/to/site-packages/phreeqpy/iphreeqc/libiphreeqc.so.0.0.0++++++++++++++++++++++ Citation ++++++++++++++++++++++
