Abstract This article presents the use of salt water springs in the Moldavian Oriental sub-Carpathians for treating certain diseases, based on archaeological discoveries and ethnographical surveys, correlated with known facts from the literature in the field. Nevertheless, what differentiates it from other similar area in Europe is the intense, unexpected continuity of traditional, nonindustrial water supplying coming from salt springs. Among the uses of salt water and halite in the area, th...

AbstractGroundwater hydrochemical evolution has influences on the rational use and conservation of water resources. This paper whichtakes MapGIS as the platform is aimed at demonstrating the evolution of shallow groundwater hydrochemistry in Guanzhongbasin (China) by adopting mathematical statistics, ratios of ion pair equivalents, geochemical simulation. The direction ofevolution is dependent on the geological, geomorphological, and hydrogeological conditions of the study area. The spatialdistr...

AbstractWashing black aluminum (Al) slag to obtain soluble salts is an important stage of the smelting slag treatment at technologicalprocess. This process is used to recover Al as a coagulant for water purification. This research aims at establishing the optimalconditions for washing (e.g. temperature (T), solid: liquid ratio (S : L), time, the recirculation waters in the system). The goal ofresearch was to determine: a) the removal with maximum efficiency of the soluble salts from black Al sla...
