Perfluoroalkyl Substances Systems Analysis Tool (PFAS_SAT)
Project description
Perfluoroalkyl Substances(PFAS) Systems Analysis Tool(SAT)
Objectives
The objective of this project was to develop a comprehensive systems analysis tool (SAT) to estimate PFAS release associated with management alternatives for a wide range of PFAS-containing wastes.
Features
Through this project, we have established an analytical framework to rigorously describe alternatives for the management of individual PFAS-containing wastes, and to quantify interrelationships between individual PFAS-containing wastes and their treatment alternatives.
The SAT estimates PFAS release to a receiving medium (air, surface water, groundwater, soil) as well as the storage of PFAS in a process (e.g., landfill, injection well) or product (e.g., thermally reactivated carbon).
The SAT includes process models for multiple treatment and disposal alternatives to estimate PFAS release as a function of the mass, composition, and properties of the waste managed.
Installation
You should install Python (3.7 or newer) and Graphviz before installing the PFAS_SAT. We recommend to use miniconda and create a new environment for the PFAS_SAT but it’s not required. Here are PFAS_SAT dependencies: (These packages are available on PyPI).
PySide2: Used for creating the user interface.
stats-arrays: Used for defining uncertainty distributions.
plotly: Used for plotting Sankey diagrams.
matplotlib: Used for data visualization.
graphviz: Used for plotting the Network.
pandas: Used for storing data in tables and manipulating them.
jupyter: Used as a command-line interface.
Here are the instructions to install PFAS_SAT with miniconda:
1- Download and install miniconda from: https://docs.conda.io/en/latest/miniconda.html
2- Update conda in a terminal window or anaconda prompt:
conda update conda
3- Create a new environment for PFAS_SAT:
conda create --name PFAS_SAT python=3.7 graphviz
4- Activate the environment (Windows users):
conda activate PFAS_SAT
Note: If you are using Linux or macOS:
source activate PFAS_SAT
5- Install PFAS_SAT in the environment:
pip install PFAS_SAT
6- Only for Windows user (If you are using Linux or macOS, go to the next step). Make sure that bin/ subdirectory of Graphviz which contains the layout commands for rendering graph descriptions (dot) is on your system path: On the command-line, dot -V should print the version of your Graphviz.
7- Open python to run PFAS_SAT:
python
8- Run PFAS_SAT in python:
import PFAS_SAT as ps ps.PFAS_SAT()
