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.
The presented research results are aimed at reducing the toxicity of wastewater containing heavy metals and ammonium ions on the environment, as well as their use as irrigation water for irrigation of industrial crops. The calculation of the volumetric static capacity for the given parameters, as well as the degree of extraction of pollution from the effluents, has been carried out. It was found that the highest percentage of absorption of heavy metals and ammonium ions after 48 hours of completed experiments is observed in zeolite with different fractions. After 12 hours of contact of the zeolite with poultry wastewater, it can be seen that 64.7% of total iron ions are absorbed, while activated carbon and gravel sand absorbed only 15.4%. Complex of activated carbon, gravel sand and zeolite 19.7%. After 48 hours of contact, the percentage of absorption of the zeolite decreased to 54.6%, and in the complex of activated carbon, gravel sand and zeolite to 3.1%, respectively, sorption was not observed in the activated carbon and gravel sand.
