What is the goal of nutrient removal in wastewater treatment?

The goal of nutrient removal in wastewater treatment primarily focuses on preventing environmental issues, particularly the proliferation of algal blooms. When wastewater containing high levels of nutrients, such as nitrogen and phosphorus, is discharged into water bodies, it can lead to excessive growth of algae. This process, known as eutrophication, depletes oxygen levels in the water, harming aquatic life and degrading water quality.

By effectively removing these nutrients during the treatment process, facilities can minimize the risk of harmful algal blooms, protect ecosystems, and maintain a healthier environment. This emphasizes the importance of nutrient removal as a critical aspect of wastewater management and environmental protection.
