EN The aim of the study was to evaluate the efficiency of surfactant removal using a laboratory hydrophyte system as well as to determine the impact of the used plant species on the removal of such compounds. The experimental system consisted of seven containers filled with expanded clay pellets planted with vegetation used in hydrophyte treatment plants. Three systems were used with different species of aquatic plants: common reed (Phragmites australis), lakeshore bulrush (Scirpus lacustris), and great manna grass (Glyceria maxima). The systems were loaded with synthetic sewage which contained a polydispersive nonionic surfactant C12E10 (5 mg/L). The experiment lasted for 27 d. The assessment of the biodegradation efficiency of the tested compound was carried out using liquid chromatography combined with tandem mass spectrometry. The reduction of C12E10 and other components of the polydispersive mixture was significant (approximately 90%). Basic relationships regarding the biodegradation of the studied compound as function of time have been established under conditions characteristic for hydrophyte sewage treatment plants. The study also included observations of plants in terms of their response to wastewater containing the C12E10 detergent.
