The article presents the results of testing filter media with various natural sorbents. When studying the absorbing properties of zeolite, charcoal and gravel sand, their properties of removing heavy metals such as Zn, Ca, Cu, Fe, as well as ammonium nitrogen were studied. During experimental studies, all studied ion exchangers showed absorption properties to varying degrees. After calculating the static capacities of each of the studied sorbents, he showed that the best absorption properties are aluminosilicate (zeolite). After completing experimental studies within 48 hours, the best moisture-absorbing effect was observed with zeolite, after 12 hours of contact with poultry wastewater, it removed 64.7 percent of the total iron, and activated carbon and gravel sand only 15.4 percent. The result of research in the study of the absorption properties of heavy metals, ammonium nitrogen ions, showed that zeolite has the highest quality wastewater treatment. The removal of ions of chemical elements was more than 60 percent within 12 hours of being in the liquid phase, in contrast to charcoal and gravel sand.
