This research work considered the purification of industrial wastewater from organic and inorganic pollutants using adsorption methods. Wastewater treatment is one of the most urgent environmental issues of our time. Industrial discharges contain harmful substances such as heavy metals, petroleum products, phenols, nitrates, and other toxic compounds that can adversely affect the environment and human health. In this study, natural zeolite and activated carbon derived from walnut shells were selected as sorbents. These materials are eco-friendly, inexpensive, widely available, and possess high adsorption capacities.

Laboratory experiments were conducted using water samples collected from various industrial areas. The results showed that both sorbents effectively removed organic and inorganic pollutants. Activated carbon was particularly efficient in removing organic compounds, while zeolite demonstrated high performance in binding heavy metals. The physicochemical properties of the water before and after treatment (pH, clarity, salinity, odor, dissolved oxygen content) were analyzed, revealing a significant improvement in water quality.

The possibility of regenerating and reusing the sorbents was also studied. After regeneration, both materials retained their adsorption properties, making the method economically advantageous. Therefore, the adsorption methods discussed in this work represent a promising and environmentally sustainable approach to the treatment of industrial wastewater and can be effectively implemented in practical applications.
