Biological nutrient removal (BNR)

Biological nutrient removal (BNR) is a process used in wastewater treatment to reduce excess nutrients like nitrogen and phosphorus that can harm the environment. Specialized microbes are employed within treatment plants to consume and convert these nutrients into harmless or less harmful forms. This not only improves water quality but also helps prevent problems like algae blooms in lakes and oceans. BNR involves carefully controlled conditions that promote these beneficial microbial processes, ensuring wastewater released into the environment is cleaner and less likely to cause ecological issues.
