Abstract
This article presents the results of scientific research conducted on the biological treatment of municipal wastewater from urban utilities using higher aquatic plants. The experiments were carried out in biological ponds with Eichhornia crassipes (Solms) and Azolla caroliniana (Willd) grown in the wastewater. After 8 days, the biomass production of these plants was 200-760 g/m² and 200-485 g/m², respectively, and the water purification efficiency reached 88-90%. A comparative analysis showed that Eichhornia was 4% more effective in purifying water compared to Azolla.
