About EPANET-MSX
EPANET-MSX (Multi-Species Extension) removes single-species limitation from EPANET's water-quality engine: you define arbitrary chemical species and their reaction kinetics — chloramine decomposition, disinfection by-product formation, arsenic adsorption, microbial regrowth — and MSX simulates them through the network alongside hydraulics.
It is the standard tool when distribution water-quality questions get chemically real. Reactions are specified in a readable text format, and the extension is scriptable through the same toolkits that drive EPANET (Python, MATLAB).
