I designed the body of a water purification system, where cloudy water enters from above. And they are absorbed by the internal openings (which are white in color). Actually, I want to solve an advection, diffusion, and adsorption equation. that these white openings have absorption coefficient. My goal is to observe the decrease in the concentration of the substances in the turbid water at the outlet, I don't care about the movement of the contaminant particles, I only care about the decrease in concentration. Can I do this in AnsysFluent?

In the Fluent model those white regions are void so won't do anything. If you just want to decrease the particle count and don't care how they move what is the purpose of the model?

The white parts are actually absorbent walls where boundary conditions can be applied and have an absorption coefficient. My goal is the entry of cloudy water from the top (as if pollution particles should be defined with scalars?) and the absorption of pollution by the same walls and the exit of clear water from the bottom so that the concentration of pollution in the outgoing water can be measured.

This looks like you've read a paper, so how was it done there? 

[sajjadghiasi92]

No, I don't know how, that's why I'm asking you, what should I do?

thanks.

I'd possibly look at scalars, but that would require some way of setting an absorption rate. Species may be a better option with a surface reaction. You need to work through the project requirements carefully, and consider things like scale, compute resource, time and training: that may also be dependent on the system being modelled.
