The aim of this work is an investigation of the possible application of Serbian natural zeolitic tuff („Igroš Vidojević“ deposit, Brus, Serbia) for improvement of the spring water quality. The concentration of magnesium in spring waters in Raška area (in Southeast Serbia) is grater than 100 mg/dm3 and is unsuitable for everyday consumption. The experiments included investigation of fluid-mechanics tests of the zeolite particles with diameters of 1.5, 4 and 6 mm in a column with diameter of 65 mm and magnesium adsorption/desorption experiments in the column with a diameter of 110 mm. The results showed that the concentration of magnesium in the spring water can be decreased below the maximum allowed concentration of 50 mg/dm3 byusing the sodium enriched zeolite bed and optimal fluid-mechanics parameters.
