Nitrogen is an important nutrient in domestic and industrial wastewater and its elevated concentration in the wetland promotes explosive growth of algae. The decomposition of the algae leads to an excessive growth of bacteria, utilizing and dissolved oxygen from water. This process of rapid algal growth leading to oxygen-starved waters is known as eutrophication.
