Phosphorus Accumulating Organisms (PAOs)

Phosphorus Accumulating Organisms (PAOs) are specialized bacteria found in certain wastewater treatment processes. They efficiently absorb and store excess phosphorus from wastewater within their cells during specific conditions. By doing so, PAOs help remove phosphorus, a nutrient that can cause environmental issues like water pollution and algae blooms if present in high levels. In treatment plants, fostering PAOs allows for effective phosphorus removal, improving water quality before it’s released back into the environment. Their activity is a natural, biological way to manage nutrient levels and protect aquatic ecosystems.
