Abstract:

The article considers the phenomenon of filtering solutions of sodium chloride and potassium through unconsolidated adsorbent systems. It gives the results of the filtering capacity study of Velizhansky peat and sand reservoir. Here are presented and described the experimental methods and apparatus. One can see the experimental data obtained by filtering different concentrated salt solutions through porous adsorbents. The salt content in the solution that passed through a sample of the porous medium was evaluated by measuring the electrical conductivity because the dependence of the electrical conductivity on the concentration in this case is linear. The mass of salt adsorbed by sample solids from the solution was determined. The authors prove the dependence of the electrical conductivity of the solution after filtration, and the ratio of the specific weight of salt absorbed per mass unit, depending on the concentration of the solution. The resulting graph shows a comparison of sand and peat with different concentrations of NaCl and KCl.
