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

For the removal of nitrogen completely through Activated Sludge Process (ASP) what would be the Solid retention time considered? Correct Answer 1-2 days

For the complete removal of Nitrogen through ASP, the solid retention time considered is 3-18 days. However, this depends on the temperature. In case the temperature is very low, then the solid retention time considered would be around 15-18 days. For higher temperatures, lower solid retention time is considered.

Consider the following statements regarding activated sludge process: 1. Industries prefer activated sludge process as it requires less space, does not produce obnoxious odours and requires less time for waste water treatment compared to trickling filter. 2. It requires skilled supervision 3. Biological treatment is enhanced because shock loadings are eliminated. Which of the above statements are correct?
