Samples water were taken for physicochemical analysis using standard methods. A electrochemical methods was used at the site to measure the pH (ionometer “І-160”), temperature (thermocouple ТХК-2588), and TDS (conductometer КВЧ5М). The concentrations of chloride, sulphate, were determined in the laboratory using AgNO3 titration method, turbidimetric method, respectively. The standard EDTA method was used to determine calcium and acid titration for alkalinity determination.


Steps to reproduce

caling and corrosive potential were determined by the differences in φ and , Langelier saturation index (LSI), and Ryznar stability index (RSI). Statistical treatment of the research results involved determining the range of data series (min–max), arithmetic mean (M), standard deviation (SD) of the corresponding sample and statistical analysis of data using the BioEstar software package (Version 5.3, MLM).
