Sažetak
The purpose of this work was development and application of the purification system suitable for the treatment of groundwater used for human consumption. The system should satisfy the following basic criteria: (a) no need for external addition of the chemicals (coagulants/flocculants, adsorbents, acids, basis) ; (b) applicable for simultaneous removal of wide range of contaminants present in the treated water (microbiological, inorganic, organic) ; (c) low sensitivity to the changes in the composition of the treated water ; (d) high quality of treated water with regard to all measured parameters. For that purpose Eastern Slavonia groundwaters with elevated values of heavy metals, color, turbidity, suspended solids, ammonia and organic contaminants were used. Due to the complexity of the composition of the treated water the purification system required electrochemical treatment using appropriate elctrochemical reactors followed by simultaneous ozonation/UV treatment. All measured parameters in the purified water were significantly lower compared to regulated values. Under the optimum treatment conditions removal efficiency of color, turbidity, suspended solids, nickel and arsenic was 100%. Removal efficiency of Fe, Mn, Cr, Zn, Cu, COD and ammonia was 99.4%, 95.7%, 98.2%, 74.0%, 99.1%, 93.8% and 94.0% respectively and increased with increasing initial concentration.
