Artificial wetlands prove effective in removing nitrogen and phosphorus from sewage.
Artificial wetlands were studied to see how well they remove nitrogen and phosphorus from wastewater. Different plants were tested in two types of wetlands. The wetland with vertical flow was better at removing nitrogen and phosphorus compared to the one with surface flow. The best removal of nutrients happened in summer and autumn, followed by spring, and the least in winter. Overall, the vertical flow wetland was more consistent in removing nutrients throughout the seasons. This study shows that artificial wetlands can effectively clean wastewater, making them a good option for improving water quality in lakes and canals.
