Modelling the (inhibitory) effect of salt on activated sludge processes

Does anyone have experience in (or can perhaps suggest a reference or two about ?) modelling the inhibition effect of salt (e.g. Cl-) on activated sludge processes? Form of the expression, parameter values, etc.?
Thanks

A simple method, reported in unpublished Israeli work, is to have an inhibition function I(C) = max(0, 1 - a C).

Some published work suggests that you can ignore inhibition, unless you propose to model adaptation to salinity:

Hi Enrico,

I was checking the forum about any answer about how to consider salinity in WEST, and I have found this former topic. The only way to do it that I can imagine is, if there is information enough to do it (influent-effluent-operation data), to calibrate the model, but it implies time and information, and usually both are not available. Have you found any new solution to consider the inhibition of the salinity?

Thank you!

No, not really Hector, sorry. Haven't work on this specific topic.
