Popis: 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.
