solvect_chlorine: Determine disinfection credit from chlorine.
Description
This function takes a water defined by define_water and other disinfection parameters
and outputs a data frame of the required CT (`ct_required`), actual CT (`ct_actual`), and giardia log removal (`glog_removal`).
Usage
solvect_chlorine(water, time, residual, baffle)
Value
A data frame of the required CT, actual CT, and giardia log removal.
Arguments
water
Source water object of class "water" created by define_water. Water must include ph and temp
time
Retention time of disinfection segment in minutes.
residual
Minimum chlorine residual in disinfection segment in mg/L as Cl2.
baffle
Baffle factor - unitless value between 0 and 1.
Details
CT actual is a function of time, chlorine residual, and baffle factor, whereas CT required is a function of
pH, temperature, chlorine residual, and the standard 0.5 log removal of giardia requirement. CT required is an
empirical regression equation developed by Smith et al. (1995) to provide conservative estimates for CT tables
in USEPA Disinfection Profiling Guidance.
Log removal is a rearrangement of the CT equations.
