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 Government of the Slovak Republic No. 354/2006 on Drinking Water. 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 color imparted by the oxidized forms that rarely goes unnoticed by the consumer. In addition, clothes and plumbing fixtures are easily stained.
The goal of this study is to compare activated natural zeolite – clinoptilolite (rich deposits of clinoptilolite are in the East Slovakia Region - found in the eighties of the past century) with imported materials Birm and Greensand in removal of iron and manganese from water. Obtained results from experiments carried out in Rohatec (Czech Republic) prove that Klinopur-Mn is suitable for removal of iron and manganese from water and it is comparable with other imported materials.
