Adsorption / Active Carbon Water Treatment and Purification

A polar substance (= a substance which is good soluble in water) cannot or is badly removed by active carbon, a nonpolar substance can be removed totally by active carbon. Every kind of carbon has its own adsorption isotherm (see figure 1) and in the water treatment business this isotherm is definite by the function of Freundlich.
