This library contains components to build models of biological municipal
wastewater treatment plants based on the Activated Sludge Model No.1 (ASM1) by the
International Association on Water Quality (IAWQ) [1,2].
The library currently is structured in following sub-libraries.
- Interfaces (partial ASM1 models and connectors)
- PreClar (primary clarifier models)
- SecClar (several secondary settling tank models)
- Examples (wastewater treatment plant models)
