PHREEQ-N-AMDTreat
PHREEQ-N-AMDTreat
PHREEQ-N-AMDTreat can be used with cost-analysis software to identify potential cost-effective strategies for treatment of acid mine drainage. Complementary tools (CausticTitration, ParallelTreatment, TreatTrainMix2) are available to simulate treatment using synthetic chemicals and natural substrates.
Equilibrium aqueous and surface speciation models are combined with kinetic models to simulate water-quality changes during treatment, including:
- Atmospheric exchange
- Iron and manganese oxidation
- Organic carbon oxidation
- Limestone dissolution
PHREEQ-N-AMDTreat outputs include:
- pH, specific conductance
- dissolved metals
- total dissolved solids
- mass of precipitated solids
Treatment Stage:
0-Untreated
1-Sedimentation Pond
2-Aeration Cascade
3-Aerobic Pond
4-Aeration Cascade
5-Aerobic Pond
6-Riprap Cascade
7-Aerobic Wetland
8-Riprap Cascade
9-Aerobic Wetland
10-Riprap
