Dear Arif,

You may input alkalinity values in meq/L or mg/L (as CaCO3) (Alk. in mg/L as CaCO3 = 50.05 X Alk. in meq/L). Also, if you have HCO3- and CO32- concentrations, you can also input those instead of alkalinity.

Regards

Both ways can be used (i.e mg/L or meq/L) as CaCO3 equivalents.

thanks a lot Bachir Achour Shuraik Kader Virendra Kumar Saxena

PHREEQC permits meq/l units only for alkalinity.

Use mg/l units.

Michael Zilberbrand thank you

Nearly every kind and type of input are possible with Phreeqe V3. See documentation in:

https://www.usgs.gov/software/phreeqc-version-3

Phreeqe converts every type of input!

See in "Description of Input for PHREEQC...."

https://pubs.usgs.gov/tm/06/a43/pdf/tm6-A43.pdf

There is a useful description with examples.

It is not necessary, conversions are made internally whatever units you use.

don't need to convert

yes need to convert

good question

you can select the units in the phreeqc module itself, no need to convert values.
