“…The sludge washed and dehydrated on filter presses, containing less than 3% of chlorides, is transferred for agricultural purposes. Meanwhile, the effluents are discharged to the sedimentary ponds (Figure 2), where their temperature is reduced, and mixing and precipitating the sediments by binding insoluble carbon dioxide from the air occur [Kasikowski et al 2008, Siwiec et al 2016]. The collected supernatant water is pumped into the Vistula River [Kasikowski et al 2007].…”

The "Soda Mątwy" plant in Inowrocław produces light and heavy soda ash by means of the Solvay method, and the production process is associated with the formation of highly saline waste, which can adversely affect all elements of the environment. In view of the existing threats, attempts are undertaken to limit the quantity and improve the quality of post-production sewage. The aim of the study is to determine the effectiveness of activities to protect the water in the area of the soda production plant in Inowrocław. The assessment of their effectiveness was based on the analysis of the current level of chloride concentration reduction at 4 measurement points around the plant and determination of the trend for further changes. In all piezometers, the concentration of chloride ions has decreased and showed the same tendency in subsequent years, which allows draw conclusions confirming high effectiveness of the activities related to water protection.

“…33 The experimental data after extraction equilibrium are listed in Table 3. The extraction complex was determined to be (HCl) 4 (R 3 N) 4 (H 2 O) 8 according to the previous study; therefore, m N235 (org) could be calculated by mass balance. Besides, the corresponding activities and activity coefficients of all the species were calculated by using the above-mentioned Pitzer equation and the results are also listed in Table 3.…”

N235 in isoamyl alcohol solution acts as an efficient extraction system for the revovery of hydrochloric acid (HCl) at very low concentrations in a coupled reactive extraction−crystallization process. In this study, the extraction equilibrium of N235 + isoamyl alcohol + HCl + H 2 O system was investigated systematically. The formation of the extraction complex in the organic phase was determined by using the experimental data and it was confirmed to be (HCl) 4 (R 3 N) 4 (H 2 O) 8 . Further, the thermodynamic model was then established by using Pitzer equation to calculate the activities of all the species. The values of the interaction parameters obtained by regression are as follows: β R 3 N,4:4:8 (org) = 2.8782 and β 4:4:8,4:4:8 (org)= 11.4764. The extraction equilibrium constant is ln K 4:4:8 = 38.0274. The thermodynamic model was demonstrated to be reliable and suitable for the N235 + isoamyl alcohol + HCl + H 2 O system.
