Dear Luka,

Regardless of what the pollutant is, you need to first search for "adsorption columns". The first source you will look at this topic is Metcalf & Eddy's "waste water engineering" book. There are explanations and sample problems for the design of adsorption columns in the book.

I need the equation that will give the relation between the height of the reactor or contactor and the diameter.

Yes, search for adsorption lectures and you need to read it. And you will find all about adsorption and adsorption isomers.

Kind regards
