You can make the argument that phosphorus reduction in wastewater is a more critical issue than nitrogen reduction is. Both nitrogen and phosphorus are essential nutrients to living things. Typically, phosphorus is the most limiting nutrient in fresh water environments, such as rivers, ponds and lakes. Salt waters (oceans and estuaries) are usually nitrogen limited. Phosphorus is an essential component in important biological molecules, including adenine tri phosphate (ATP), adenine di phosphate (ADP) and Deoxyribose Nucleic Acid (DNA). Phosphorus is relatively scarce in the Earth’s crust. Countries where phosphate rock is still plentiful are antagonistic to the interests of the United States. Phosphorus can be removed from wastewater by pollution prevention (changing product formulations) to not include phosphorus, diverting plumbing flows with significant phosphorus concentrations to storage, and using electrochemical methods to sequester phosphorus into multiple minerals.
After this session, attendees will be able to:
1. Recognize which biological molecules in a provided list contain phosphorus.
2. Pick two phosphorus removal techniques from a provided list.
3. Describe the treatment process behind one phosphorus removal technology.
4. Detail which water bodies are phosphorus-limited from a provided list.
Ideal Audience: Designers and operators.
