The goal of edwards97 is to implement the Edwards (1997) Langmuir-based semiempirical coagulation model, which predicts the concentration of organic carbon remaining in water after treatment with an Al- or Fe-based coagulant. Methods and example data are provided to optimise empirical coefficients.

This package is experimental, under constant development, and is in no way guaranteed to give accurate predictions (yet).


You can install the development version from GitHub with:


This is a basic example which shows you how to solve a common problem:

Using the fit, you can make predictions about unknown inputs:
