Abstract

Research on the use of sorbents to remove anions from wastewater after soda production was made due to the need to protect waters against pollution at the source of its formation. In the case of industrial plants introducing sewage to surface waters, this requires modification of the production line or an additional stage of wastewater treatment, which will prevent from polluting the environment. Wastewater generated in the Solvay soda ash production process is characterized by strong alkaline reaction, high electrolytic conductivity and high concentrations of chlorides, ammonia, sulfates, phosphates, calcium, potassium, sodium and magnesium. The paper presents results of the research aimed at removing chloride, sulfate and phosphate anions from wastewater from calcinated soda production using three sorbents: Halosorb, Compakt and Damsorb K. The ion removal process was carried out using a dynamic method with varying deposit load in the range from 0.579 m3/(m2h) to 1.937 m3/(m2h). Concentrations of all tested anions were reduced, which indicates a high potential of the method and possibility of further, more detailed studies
