Small individual household wastewater treatment plants not always operate well. Consequently, the concentra-tions of ammonium nitrogen and phosphate phosphorus are exceeded. The aim of the work was to examine the zeolite as a wastewater tertiary treatment material and propose environmentally friendly ways to solve fresh water problem.  During experiment zeolite filter material was tested. In the article is analyzed zeolite filtering efficiency of nutrient removal from wastewater. Zeolite filler most effective was against ammonium nitrogen (99.9–10.1%) and relatively less effective against phosphate phosphorus (51.2–4.9%).
