About ORCHESTRA

ORCHESTRA:

  • is a computer program for calculating chemical speciation and reactive transport processes.
  • is written in Java and runs on Windows, Linux and Apple OSX.
  • can be downloaded for free from this site.
  • has a graphical user interface for quickly setting up  chemical equilibrium models.
  • ui_1
  • has on-line example systems for batch and transport calculations
  • comes with a large set of  adsorption models
  • can be used to simulate equilibrium reactions , kinetically controlled reactions, radioactive decay, transport
  • can create predominance / pe-pH diagrams:
  • predomscreenPu+4PredomAS
  • allows users to construct new models by defining new model object classes and keywords.
