Abstract: The goal of the present study was to evaluate the efficiency of filters filled with Rockfos for removal of phosphorus (Total-P) from domestic wastewater.Rockfos is a material obtained by calcination of carbonate-silica rock (opoka) at a temperature of 900 °C.A field study was conducted in two filters with volumes of 2.0 and 0.8 m 3 which were components of hybrid constructed wetlands with an average capacity of 2.0 m 3 /L, located in two national parks in south eastern Poland.Samples of the influent to and the effluent from the filters were analyzed for Total-P concentrations and pH.Eighty sewage samples were tested over a five year study period.It was shown that the test filters removed Total-P with an average efficiency of 31.5% and 30.2% and that they could be successfully used to remove phosphorus from domestic wastewater in small wastewater treatment plants.
