The Use of Sorbents for the Removal of Selected Anions from Wastewater after Production of Soda Ash

Gołub Adam, Piekutin Janina

Journal of Ecological Engineering

Vol. 21, nr 2

104--110

The research on the use of sorbents to remove anions from the wastewater after soda production was conducted due to the need to protect waters against the pollution at the source of its formation. In the case of industrial plants introducing wastewater to surface waters, this requires modification of the production line or an additional stage of wastewater treatment, which will prevent pollution of the environment. The wastewater generated in the Solvay soda ash production process is characterized by strong alkaline pH, high electrolytic conductivity and high concentrations of chlorides, ammonia, sulfates, phosphates, calcium, potassium, sodium and magnesium. The paper presents the results of the research aimed at removing the 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 a varying deposit load in the range from 0.579 m3/(m2h) to 1.937 m3/(m2h). The concentrations of all tested anions were reduced, which indicates a high potential of the method and possibility of further, more detailed studies.

Monitoring of Groundwater in the Area of a Reclaimed Municipal Waste Landfill

Vol. 20, nr 8

262--268

The paper presents the quality of groundwater around the municipal waste landfill in the town of Kolonia Lipsk. The structure, location and operation of the landfill are presented. The aim of this work was to assess the state of groundwater quality around the reclaimed Municipal Waste Landfill in the city of Kolonia Lipsk, closed in 2012. The research was carried out in 2015 with the frequency of once a quarter for 10 selected indicators characteristic for the water pollution assessment in the area of municipal waste landfills. The water for testing was taken from three piezometers located in the vicinity of tested object, at different distances and at various depths in farm wells. Although the landfill has not been operating since 2012, the contamination of groundwater around the landfill has been identified. The lack of landfill bottom sealing and the lack of surrounding ditches indicate that the condition will last for some time.
