Allow precipitation but not dissolution


 Share

Recommended Posts

Hi,

 

I am trying to model a dynamic system in which I want to allow a mineral to precipitate once the saturation ratio exceeds one but when the saturation ratio later declines below one, I do not want it to re-dissolve. Can anyone suggest approaches as to how I might do this in GWB (I have version 10 Professional).

 

Many thanks,

Ross.

Hi Ross,

 

I think you’ll want to use kinetics for this problem. To get the desired functionality, you’ll need to write a simple custom rate law. There is an example very similar to the problem you’re describing in section 5.2, Rate law scripts, of the GWB Reaction Modeling Guide.

 

Hope this helps,
