Natural minerals impact on physical and chemical parameters of potable water

The article presents the research results dealing with influence of such natural minerals as flint and shungite in relation to following water parameters pH, TDS, conductivity, cations (NH4+, K+, Na+, Mg2+, Sr2+, Ba2+, Ca2+) anions (Cl−, SO42−, NO3−, F−, СО32−). It was found that crushed added more significantly increases hydrogen index if compared sedimentation. Simultaneously total mineralization decreases (causing electric 28,4 al conductivity decrease). Considerable decrease calcium ions concentration (by 36.0 %) detected infused by 20.5% flint. increase K+ (46.3%) revealed. As for F− decreased both - These are recommended treatment tap characterized increased hardness excessive fluoride content.
