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
combined_chlorine_chain and _once)
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
chemdose_ph_chain and _once for
applying models to data frames.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
