This phenomenon has been researched for decades, for example Iwasaki (1937) presented a mathematical model that described the removal of particles based on solids influent load, diameter of media and depth of media. Similar to other methods of filtering water, the filter removes particles larger than the size of the pores in the filter material. The active carbon absorbs compounds such as chlorine.
