Removal of magnesium in spring water using the natural zeolite in a continuous flow system

The aim of this work is an investigation of the possible application of Serbian natural zeolitic tuff ("Igroš Vidojević" deposit, Brus) for improvement of the spring water quality. Concentration of magnesium in spring waters in Raska area (in southeast Serbia) is grater then 100 mg/dm3 and is unsuitable for everyday consumption. The experiments includied investigation of fluid-mechanics tests of the zeolite particles with diameters of 1.5 mm, 4 mm 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 using sodium enriched zeolite bed and using optimal fluid-mechanics parameters, the concentration of magnesium in the spring water can be decreased below the maximum allowed concentration of 50 mg/dm3.
