The constant search for new mass filter, as well as improving existing ones, contributing to the search for optimal solutions, combining both high process efficiency and low operation costs. However, that the new deposit found its place in water technology, should start research to determine its usefulness in the process of filtration. The aim of this study was to analyzed and evaluated the effectiveness of filtration two unknown, porous filter masses. Therefore, it was examined the behavior of filter bed by filtration in the laboratory, to assess the efficiency of removal of particular contaminants from the water. Chemical indicators were examined in the model water flowing through the mass, such as: pH, electrolytic conductivity, CODMn, dry residue, chloride concentration, ammonium concentration, nitrate (V) concentration, total hardness, iron and manganese concentration. It has been proved that the bed X-1, which has an less equivalent particle diameter, efficiently removed contaminants from the water compared to filter bed X-2. Filter beds X-1 and X-2 does not purify the water to the value of the regulation of the minister of health. The parameters have exceeded values after filtration are: iron concentration, ammonia concentration, manganese concentration and CODMn. It is concluded that probably gave to the second stage of a two-stage filtration.
