QSDsan: Quantitative Sustainable Design for Sanitation and Resource Recovery Systems

What is QSDsan?

QSDsan is an open-source, community-led platform for the quantitative sustainable design (QSD) [1] of sanitation and resource recovery systems [2]. It leverages existing platforms such as BioSTEAM [3] with enhanced features tailored to sanitation an resource recovery technologies. Through the integration with DMsan (decision-making for sanitation and resource recovery systems), this platform can be used to guide the research, development, and deployment (RD&D) of early-stage technologies considering location-specific parameters and stakeholder priorities.

Installation

If you are new to Python, we are developing beginner tutorials with step-to-step guidance starting from setting up your Python environment.

The easiest way is through pip, in command-line interface (Anaconda prompt, terminal):

pip install qsdsan

If you need to update:

pip install -U qsdsan

Or for a specific version (replace X.X.X with the version number):

pip install qsdsan==X.X.X

If you want to install the latest GitHub version at the main branch:

pip install git+https://github.com/QSD-Group/QSDsan.git

You can also download the package from PyPI.

Note that development of this package is currently under initial stage with limited backward compatibility, please feel free to submit an issue for any questions regarding package upgrading.
