Study of the orthopolyphosphate specimen "SeaQuest Liquid" for anticorrosion and stabilization water treatment by M. I. Romashchenko, O. V. Kovalenko, E. M. Matselyuk, D. V. Charny, V. A. Prokopov

“…A characteristic feature of this water supply system is the use of various sources of water supply - groundwater and surface waters of the Desna and Dnieper rivers. The results of the calculation of water corrosivity carried out at the Institute based on the chemical analysis of the quality of water taken from 29 wells at the research object showed that the Langelier indices obtained using the calculation formulas for all sampling points are in the range from 0,89 to 1,77, which indicates the continuous and significant corrosive activity of water at all sampling point. …”
