Hi all..

I am currently doing an experiment of filtration of filtering CaCO3.

There's a question in the experiment that ask about when will CaCO3 be an incompressible cake. From my understanding, CaCO3 is an incompressibe cake. However to my surprise, CaCO3 can be a compressible cake as well providing the conditions are there , especially the pressure difference. So now, does anyone know what is the range of pressure in which CaCO3 is a compressible cake and incompressible cake?

Really thanks alot for those who replied me!!!

Thanks

Desmond

Hi,
Since you are doing experiments, I would suggest that you design experiments from which you can obtain data to fit to the Darcy Filtration equation and thus obtain values for the cake resistance.
