“…Plants involved in the production of soda ash belong to the chemical industry. Most often in their production processes they use the Solvay method, which is associated with the formation of saline waste [1][2][3]. Limiting the negative impact on the environment consists of pre-treating postproduction sewage and limiting its contact with underground water [4].…”

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.

“…According to statistics [6,7], in China, the production of sodium carbonate using the ammonia soda process exceeds 10 million tons per year, and the resulting SR reaches 3 million tons per year [8]. At present, building a storage yard next to the soda plant and discharging the SR into the storage yard is a common way to dispose of the SR [9][10][11]. However, this approach has the disadvantage of occupying amounts of land, polluting the local ecology, and failing to achieve sustainable resource and economic development [12,13].…”

Soda residue (SR), a waste by-product of sodium carbonate production, occupies land resources and pollutes the environment seriously. To promote the resource reusing of waste SR, this paper studies the feasibility of utilizing SR for the preparation of soda residue soil (SRS) through laboratory and field tests. The SR and fly ash (FA) were mixed with six different proportions (SR:FA is 1:0, 10:1, 8:1, 6:1, 3:1, 1:1) to prepare SRS, and the optimum water content, maximum dry density, shear strength, and unconfined compression strength of the SRS were measured. The representative SRS (SR:FA is 10:1) was selected to investigate the compression performance and collapsibility. The preparation and filling method of SRS in the field was proposed, and the effects of gravel, sand, and lime on the mechanical properties of SRS were studied through field tests. The results show that the addition of FA contributed to the strength development of SR, and the addition of lime, sand and rubble have a significant effect on the subgrade bearing capacity of SRS. The subgrade bearing capacity and deformation modulus of SRS in field tests is more than 210 kPa and 34.48 MPa, respectively. The results provide experimental basis and reference for the preparation of SRS, the scientific application of SRS in geotechnical engineering to promote sustainable development.

“…The turn of the 19th and 20th centuries was synonymous with the rapid development of industry, which often led to major changes in all elements of the natural environment (soils, groundwater, surface water, air, plants, animals) [1][2][3][4]. A great example of this is the chemical industry related to the production of soda ash-formerly by the Leblanc method, now by the Solvay method.…”

“…This wastewater, after initial treatment, is discharged to sediment ponds, where its temperature is lowered and the suspended matter settles to the bottom, forming solid waste [8,9]. For each kilogram of soda ash, approximately 0.5 kg of sodium chloride and 1 kg of calcium chloride is formed [3,4]. A significant amount of liquid form, high salt concentration and high wastewater reactions create technical, economic and ecological problems.…”

The aim of the work was to determine whether the waste accumulated on the reclaimed sedimentary pond near the Janikosoda Production Plant in Janikowo is still a source of pollution of groundwater. On one of the ponds near the Production Plant in Janikowo, three points were located, in which drilling was done up to the bottom of the layer of solid waste. In each point, samples of sediments were taken to determine electrolytic conductivity and chloride concentration. In order to examine the level of groundwater pollution in the area of the Production Plant, four points around the sedimentary ponds were identified, in which regular monitoring of chloride ions has been carried out since the 1980s. Based on analysis, it was concluded that chlorides are leached from the sediments deep into the soil profile by rainwater and, with high probability, also by water seeping from the adjacent slag pond. Sedimentary ponds are still an important source of pollution released into soils and groundwater around the plant. Nevertheless, chloride concentration in solid waste and groundwater in the area of sedimentary ponds has decreased in the last 20 years.
