Removal of Manganese and Iron from Groundwater in the Presence of Hydrogen Sulfide and Ammonia

Presence of iron and manganese in water not only affects the organoleptic properties of water, but also can cause a number of problems in drinking water treatments. Their removal in drinking wa-ter preparation processes becomes more complicated in the presence of hydrogen sulfide and ammonia in water. There are certain commercialized products at the market that are used for removal of manganese, iron and ammonia, but it is of crucial importance to establish an appropri-ate order of removal in the technological process during drinking water treatment. Through the various combinations of commercialized filtration media, the removal of iron, manganese, hydro-gen sulfide and ammonia, was being examined and on the basis of obtained results their effec-tiveness was estimated. Research results have shown that hydrogen sulfide is pollutant that caus-es problems during the adsorption in removing manganes. Ammonia, which is bonded to hydro-gen sulphide influences the volume of treated water when it comes to removing the iron and manganese. Decrease in the concentration of hydrogen sulfide at the entrance to Filtersorb FMH for four times, has led to an increase in the volume of treated water in the amount of two times
