The UML below shows the structure and core Python classes implemented in
QSDsan. Each class is represented by a box containing the class name (bold, top part of the box) with select data (middle part of the box) and method (end with parentheses, bottom part of the box) attributes. The
WasteStream classes in blue are inherited from the
Stream classes in Thermosteam with the addition of wastewater-related attributes. The Process class in red enables dynamic simulation of Component objects’ transformation during kinetic processes (e.g., degradation of substrates). The
Model classes in yellow are inherited from BioSTEAM with added capacities for dynamic simulation and handling of construction inventories. Green boxes including
LCA are implemented in
QSDsan to enable LCA functionalities.
