ABSTRACT: 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 water
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 appropriate order of removal in the
technological process during drinking water treatment. Through the various
combinations of commercialized filtration media, the removal of iron,
manganese, hydrogen sulfide and ammonia, was being examined and on the basis of
obtained results their effectiveness was estimated. Research results have shown
that hydrogen sulfide is pollutant that causes problems during the adsorption
in removing manganes. Ammonia, which is bonded to hydrogen 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, followed by the breakthrough point of concentration of
manganese. For complete usage capacity of commercialized products for the removal
of these pollutants, finding their mutual bond in compounds which are present
in the water, is of the importance.
