Removal of nitrogen and phosphorus by aboveground biomass of Phragmites australis in Constructed Wetland System under the conditions of temperate continental climate.

The contribution of this paper is reflected in the obtained results for population density, reed biomass, and reed efficiency in the process of accumulation and removal of nitrogen and phosphorus as the main factors of accelerated eutrophication of aquatic ecosystems, the recipients of municipal wastewater. These results are significant because there is not enough data concerning this topic in the temperate continental climate of Southeast Europe. In addition to this, Constructed Wetland System is the first system of this kind, developed in our country that has been functioning for past 18 years. Due to this, the results are encouraging the application of CWS for a large number of smaller settlements in Southeast Europe as well as in other similar areas. Also, the results obtained in this paper can be useful to all those who are committed to the environmental approach and are engaged in research related to the use of reed in the process of municipal wastewater treatment.
