Nutrient Removal is an important process in water treatment where specific substances like nitrogen and phosphorus are taken out of wastewater before it's released back into the environment. Think of it like a cleaning system that removes harmful elements that could cause problems in rivers and lakes. This process is crucial for protecting the environment and meeting clean water standards. Water treatment facilities use this term to describe both the equipment and methods they use to clean water. You might also hear it called "nutrient reduction," "biological nutrient removal," or "advanced wastewater treatment."
