ABSTRACT

In over 38 percent of the groundwater drinking water sources in Slovakia, iron and manganese concentrations exceed the recommended levels set by Regulation of the Slovak Republic No. 247/2017 on Drinking Water [1]. Iron and manganese are not considered health hazards, although micro-environments may be supported in wells and distribution systems which harbor microorganisms. The main concern with these metals is the turbidity and color imparted by the oxidized forms that rarely goes unnoticed by the consumer [2].
The objective of the study was to compare removal of dissolved iron and manganese from water by using the natural zeolite – clinoptilolite mined in the territory of Slovakia with imported filtration material – Birm. Obtained results from experiments carried out in the groundwater in locality Kolárovo and Čičov indicate that Klinopur-Mn can be used for removal of iron and manganese in water treatment process (contact manganese removal). This material is comparable with imported Birm.

Keywords: drinking water, removal of iron and manganese, contact filtration, modified clinoptilolite, Birm
