solvedose_alk

This function calculates the required amount of a chemical to dose based on a target alkalinity and existing water quality.
Returns numeric value for dose in mg/L. Uses uniroot on the chemdose_ph function.

Provides multiple water chemistry-based models and published empirical models in one standard format.
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),
