tidywater 0.7.0

New features

• chlorine and chloramine decay: chemdose_chlordecay
• New water slots for chloramine chemistry: combined_chlorine, nh2cl, nhcl2, ncl3
• solvemass_solids separates functionality from solvecost_solids to solve lb/day
• biofilter_toc, chemdose_chlordecay, ozonate_bromate, and solvect helpers now available.

Breaking changes

• chemdose_ct renamed solvect_chlorine
• ozonate_ct renamed solvect_o3
• tot_ocl slot in water renamed free_chlorine
• define_water argument changes: tot_ocl changed to free_chlorine, added combined_chlorine
• Helper function (_chain and _once) behavior change: if multiple values are specified for multiple arguments, all combinations are used.

tidywater 0.6.2

• CRAN resubmission.
• Minor changes to DESCRIPTION and examples using plan

tidywater 0.6.1

• Initial CRAN submission.
• Fix R CMD check notes

tidywater 0.6.0

New features

• biofilter_toc updates the bdoc water slot
• pac_toc helper functions _chain and _once

Breaking changes

• biofilter_toc argument, o3_dose, was replaced with ozonated, which accepts TRUE or FALSE inputs

tidywater 0.5.0

Fixes

• default temperature is now 25C
• corrected enthalpy of reaction for ammonium ion
• completed PAC models

New features

• chemdose_ct: CT calculations, including CT actual, CT required, and giardia log removal
• solvecost_ family: cost calculations, including chemicals, power, solids, and labor
• solvemass_ :convert chemical doses from mg/L to lb/day
• solveresid_o3: ozone decay model and corresponding helper function from WTP model
• ozonate_ct: ozone CT model
• validate water function, not exported but useful for function writing
• chemdose_f: fluoride model for alum addition. Requires site specific fitting.
• biofilter_toc: biofiltration model (Terry & Summers)
• added ACH to chemdose_ph

Breaking changes

• total ammonia water slot changed from tot_nh4 to tot_nh3

Code structure changes

• renamed and rearranged R scripts to better find functions and associated helper functions
• update most functions to use base R, and only use dplyr functions where necessary (increase speed)

tidywater 0.4.0

Fixes

• solve_ph code updated to handle starting po4 concentration

New features

• convert_watermg for cleaner water exports
• bromate formation models
• ammonia in pH chemistry
• new water slots for F, Fe, Al, etc
• helper functions for chemdose_dbp
• PAC models (incomplete)

Breaking changes

• treatment slot renamed “applied_treatments”
• solve_ph changes. Should only see different values when po4 is in the water.
• Added hydration to ferric sulfate and renamed coagulants for consistency.
• pluck_water doesn’t allow specification of output_column. It is named by default from the input and parameters. Improved pluck does allow multiple parameters and waters in one function.

tidywater 0.3.0

Fixes

• Raw water DBP models do not require UVA
• Updated incorrect DBP model coefficients

New features

• CaCl2 now included in possible chemical addition.

Breaking changes

• define_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 corrosion

tidywater 0.2.1

Bug fixes

• Small vignette changes to fix package build.

tidywater 0.2.0

New features

• TOC removal through coagulation, chemdose_toc and matching _chain and _once helper functions.
• DBP formation from coagulation, chemdose_dbp. No helper functions yet except summarise_dbp
• Calculation of corrosion indices, calculate_corrosion and summarise_corrosion with helper functions.
• Theoretical lead solubility dissolve_pb with helper functions.
• Helper function pluck_water to pull one slot from a water column in a data frame.

Breaking changes

• Changes in S4 water class and define_water to handle more water quality parameters.

Calculation changes

• Activity is calculated from ionic strength and used in pH calculations.
• Ionic strength is based on TDS or conductivity and is recalculated when appropriate in balance_ions and chemdose_ph

tidywater 0.1.0

• Initial release
• Acid/base equilibrium with assumption activity = concentration
• Helper functions _chain and _once for applying models to data frames.
