| Summary: | Wastewater generated in the soda ash production process can be characterized by a strong alkaline reaction, high electrolytic conductivity and high concentration of chlorides, ammonia, sulphates, phosphates, calcium, potassium, sodium and magnesium. Protection of water against pollution should be not only connected with rational management of water resources and the restoration of the water environment to the required state, but also with prevention of pollution. It is an increasingly important element of protective measures. The strict control of pollution at the source is important. Therefore, it is necessary to develop methods of broadly defined waste disposal from industry. The article presents the results of research aimed at the removal of sodium, calcium, potassium, magnesium and ammonium ions from wastewater from soda ash production using three sorbents: Halosorb, Compakt and Damsorb K. The ion removal process was carried out dynamically with different load on the deposit. The concentration of all these anions was reduced to some extent, which indicates the possibility of further, more accurate tests. It was found that the type of sorbent does not differentiate the results of the experiment. The load on the deposit, on the other hand, has an impact on the efficiency of sorbents in wastewater treatment.
