calculate_activity

This function calculates activity coefficients at a given temperature based on equation 5-43 from Davies (1967), Crittenden et al. (2012)

Provides multiple water chemistry-based models and published empirical models in one standard format.
As many models have been included as possible, however, users should be aware that models have varying degrees of accuracy and applicability.
To learn more, read the references provided below for the models implemented.
Functions can be chained together to model a complete treatment process and are designed to work in a 'tidyverse' workflow.
Models are primarily based on these sources:
Benjamin, M. M. (2002, ISBN:147862308X),
Crittenden, J. C., Trussell, R., Hand, D., Howe, J. K., & Tchobanoglous, G., Borchardt, J. H. (2012, ISBN:9781118131473),
