_df replace chain and
once functions. Use pluck_cols = TRUE to mimic
once behavior, although it will always return a water
column as well.solvect_chlorine based on
the EPA Guidance Manual Table E-7 (1991)modify_water can now modify multiple water slots at
once. Note that in order to modify multiple slots using
modify_water_df, all input arguments must be included as a
list.chemdose_ph. In
addition to changing pH, dosing acetic acid will also update TOC and DOC
of the input water.regulate_toc now available for calculating TOC removal
compliancegacrun_toc, gac_toc, and
gacbv_toc added to predict TOC removal from GAC treatment
using either the EPA WTP model (2001) or the Zachman and Summers (2018)
model. Different functions provide different output types: a data frame
of the TOC breakthrough curve, a new water with updated TOC, DOC, and
UV254 water slots, or the necessary bed volumes to stay below the target
effluent TOC. See individual functions for documentation.pluck_water and _df helpers sped up by
relying on base R instead of purrrchemdose_toc can now account for doc removal due to
lime softening from the WTP Model (2001). To implement, use the
caoh2 argument.opensys_ph added to predict pH and alkalinity
of an input water in an open carbonate system at equilibriumplot_lead added to graph the pH vs DIC
contour plot for lead solubilityalk and
alk_eq represent the total alkalinity, and individual
alkalinities due to carbonate, phosphate, ammonium, borate, silicate,
and hypochlorite have been added as individual slots (eg.
carbonate_alk_eq)._chain and _once functions have been
deprecated. Replace with _df functions. Code should be
similar, but has slightly different outputs.output_water = "defined",
old default output_water = "defined_water". See function
documentation for new defaults.alk) now accounts for phosphate,
silicate, borate, hypochlorite, and ammonia. Could have a minor impact
on final pH and alkalinity calculations in waters with those
compounds.|>chemdose_ph chemicals: CaOCl2, CaSO4, HNO3, KMnO4,
NaF, and Na3PO4dissolve_cu predicts the concentration of
copper given pH, DIC, and phosphate based on the empirical model
described in Lytle et al. (2018). dissolve_cu_once can also
predict copper for waters in a data frame.chemdose_dbp can now input custom fitting coefficients
as a data framechemdose_ph_once and chemdose_toc_once are
back and only return relevant waters slots in its output.decarbonate_ph: function to remove CO2 (H2CO3) from a
water and determine the new pH (and division of ions)modify_water: function to modify individual slots in a
water that handles unit conversionsapplied_treatment slot removed from water. Was not
providing any benefit and added complexity. Should be the responsibility
of the user to track.h2co3 slot added to water class calculated
based on {H} and total carbonate.chemdose_ph warns when ion water slots aren’t updated
due to NA slots.solvedose_ph updated search range to allow for more
water qualities without erroring. Updated search process results in
slightly different outputs._toc functions are DOC-based and previously assumed no
particulate TOC removal. In reality, virtually all particulate TOC is
removed with other particulates, so models have been updated to return
TOC = DOCchemdose_toc custom coeff now accepts a data frame
instead of a named listwater class.calculate_corrosion now outputs a data frame with the
corrosion indices as columns. calculate_corrosion_chain
removed because the base function has a numeric output.calculate_corrosion updated CCPP search range to allow
for more water qualities without erroring.solvect_o3 and solveresid_o3 now return
zero instead of NaN when the input dose is zerochemdose_chloramine warnings.calculate_corrosion expanded CCPP search range (fewer
errors)_chain and _once)
behavior change: can now specify column name unquoted (eg, alum =
AlumDose)_once) helper functions because the
desired output is almost never all water slots as columns. Refer to
pluck_water(parameter = "all") for same behavior.pac_toc now constrained to accept a smaller range of
doses and times. The form of the equation was allowing negative TOC
outputs.define_water, chemdose_ph,
blend_waters, and other pH related functions slightly
impacted by a fix in concentration vs activity. Previous code assumed pH
= 10^-[H+], code has been corrected to pH = 10^-{H+}define_waterconvert_unitschemdose_chloramine: chloramine formation model given
chlorine, ammonia, timechemdose_chlordecay now has argument,
use_chlorine_slot. Function can now use chlorine dose
and/or free_chlorine or combined_chlorine slots.chemdose_chlordecaycombined_chlorine, nh2cl, nhcl2,
ncl3solvemass_solids separates functionality from
solvecost_solids to solve lb/daybiofilter_toc, chemdose_chlordecay,
ozonate_bromate, and solvect helpers now
available.chemdose_ct renamed solvect_chlorineozonate_ct renamed solvect_o3tot_ocl slot in water renamed
free_chlorinedefine_water argument changes: tot_ocl
changed to free_chlorine, added

behavior change: if multiple values are specified for multiple
arguments, all combinations are used.plandefine_water now has arguments for “ca” and “mg” and no
longer has “ca_hard”.summarize_dbp and summarize_corrosion
removed. summarize_wq now takes arguments to summarize
general, ions, dbps, or corrosionchemdose_toc and
matching _chain and _once helper
functions.chemdose_dbp. No helper
functions yet except summarise_dbpcalculate_corrosion
and summarise_corrosion with helper functions.dissolve_pb with helper
functions.pluck_water to pull one slot from a
water column in a data frame.water class and define_water
to handle more water quality parameters.balance_ions and
