Study of the Healing Properties of Natural Sources of Georgia and Modeling of Their Purification Processes

Abstract

The studies were conducted on the natural waters of Georgia: Gortubani and Naminauri (Adigeni region), Danisparauli, Dandalo and Makhinjauri (Adjara region) which exhibit medicinal properties. The following water indicators were determined: titratable acidity, electrical conductivity, hardness, the content of solids, sulfates, chlorides, hydrocarbonates, nitrates, ammonium salts and metals. These indicators were determined in the source water, as well as in the concentrate and permeate obtained by ultrafiltration. The productivity of the ultrafiltration process was determined, its dependence on the duration of the process, the applied pressure and the location of the spring. The productivity of the Danisparauli water ultrafiltration process decreases with time; the productivity remains unchanged during the filtration of the Makhinjauri and Naminauri waters; during ultrafiltration, the titratable acidity of the Makhinjauri water increases significantly, by 66.5%, that of the water Naminauri by 36.6%, the titratable acidity of the Danisparauli water remains unchanged, the sulfide ion content in the Makhinjauri water increases by 12%, and in the Naminauri water by 35.5%, the chloride content in the process of concentrating practically does not change. It was found that all the investigated waters are contaminated with heavy metals and the population should not use them for treatment. The data obtained can be used to simulate the purification of natural sources.
