Why is phosphorus removed prior to discharge to receiving waters?

• A. It is harmful to humans
• B. It causes excessive algae growth
• C. It clogs filters
• D. It is a heavy metal

Answer: (B)

Phosphorus is removed prior to discharge to receiving waters because it causes excessive algae growth. When phosphorus enters water bodies, it acts as a nutrient that encourages the rapid growth of algae, a process known as eutrophication. This excessive growth can deplete oxygen levels in the water, harm aquatic ecosystems, and lead to the death of fish and other organisms. Algal blooms can also produce toxins that affect both aquatic life and human health, making it essential to manage phosphorus levels to maintain water quality and ecosystem health.
