What is an essential benefit of nutrient removal in water treatment?

Nutrient removal in water treatment primarily serves to prevent eutrophication in receiving waters. Eutrophication is a process where water bodies become excessively rich in nutrients, particularly nitrogen and phosphorus, leading to excessive growth of algae. This algal bloom can deplete oxygen levels in the water, harming aquatic life and disrupting ecosystems.

By removing these nutrients from wastewater before it is discharged into rivers, lakes, or oceans, water treatment facilities help maintain the health of these ecosystems. Reducing the risk of eutrophication ensures that aquatic environments remain balanced and supports biodiversity.

While other benefits, such as lowering energy consumption or reducing color and odor, may result from various treatment processes, the primary focus of nutrient removal is to protect aquatic ecosystems from the negative impacts associated with nutrient overload.
