Abstract

Based on experimental results we establish that the rate of removal of biogenic elements from model solutions of nitrates and phosphates depends on the species and biomass of macrophytes, as well as on solution temperature and initial pollutants concentration. The most significant factors affecting the intensity of hydro-phytoremediation were found and the limits of these factors were determined. We found that the macrophytes do not remove the biogenic elements from solutions with concentrations of ammonium and nitrates above 100 mg/l and phosphates above 50 mg/l. Regionally distributed submerged macrophytes that remove the nutrients most intensively are Potamogeton, Myriophyllum, Nitella. At equal concentrations of phosphates and nitrates, the past is absorbed faster.
