Re: Question : Phreeqc




> I have a question related to the transport or non transport of
precipitated minerals when running a transport simulation with
Phreeqc/Llna.dat.
When precipitation occurs in one cell, is the total amount of precipitate
transported in the next cell ?

Only dissolved species are transported from one cell to the next. All
EQUILIBRIUM_PHASES, SURFACE, EXCHANGE, KINETICS, SOLID_SOLUTIONS, and
GAS_PHASE entities remain in a cell.

> By consequence, is there a simple way with Phreeqc, to constraint this
transport in two cases : (1) full transport of precipitate or (2) no
transport of precipitate species from cell(i) to cell(i+1) ?

Case 2 describes the algorithm of PHREEQC and is the only one possible.
