Bases: object

Fractionation parameters for characterize_influent() / fractionate().

Defaults are the SUMO Sumo1 raw-influent tool’s municipal values; the nitrogen-balance contents iN_xb / iN_xp are ASM1’s i_XB / i_XP.

Parameters:

  • f_sccod (float) – Filtered COD (1.5 um, incl. colloids) as a fraction of total COD. Used only when filtered_cod is not measured.

  • f_scod (float) – Flocculated-filtered (truly soluble) COD as a fraction of total COD. Used only when flocculated_filtered_cod is not measured.

  • f_su (float) – Soluble unbiodegradable COD as a fraction of filtered COD. Used only when soluble_inert_cod is not measured.

  • f_xu (float) – Particulate unbiodegradable COD as a fraction of total COD.

  • f_oho (float) – Heterotroph biomass COD as a fraction of total COD.

  • f_xe (float) – Endogenous-product COD as a fraction of the heterotroph COD.

  • f_cu (float) – Colloidal unbiodegradable COD as a fraction of colloidal COD.

  • f_snh (float) – Ammonia as a fraction of TKN. Used only when ammonia is not measured.

  • iN_sb (float) – Nitrogen content of soluble biodegradable substrate (g N / g COD), used to set SND.

  • iN_xb (float) – Nitrogen content of biomass / endogenous products (g N / g COD), ASM1’s i_XB / i_XP; used to close the TKN balance onto XND.

  • iN_xp (float) – Nitrogen content of biomass / endogenous products (g N / g COD), ASM1’s i_XB / i_XP; used to close the TKN balance onto XND.

  • caco3_eq (float) – g CaCO3 per equivalent: SALK [mol/m3] = alkalinity [mg CaCO3/L] / caco3_eq.

  • default_alkalinity_mol (float)
