For the removal of phosphorous through Activated Sludge Process (ASP) what would be the Solid retention time considered?

For the removal of phosphorous through Activated Sludge Process (ASP) what would be the Solid retention time considered? Correct Answer 2-4 days

For the removal of phosphorous through ASP, the solid retention time considered is 2-4 days. However, this depends on the temperature. In case the temperature is very low, then the solid retention time considered would be around 4 days.
