      - This is a very useful video that we also need to go over it together. The video covers the activated sludge process, the main secondary biological process used in virtually all wastewater treatment plants worldwide.

      - Please, watch the entire video of the activated sludge and discuss the following Qs: 

      Q1: What is the difference between activated sludge and the deactivated one?

      Q2: What is the grit? Where does it come from and why it is important to be removed?

      Q3: Where is the activated sludge system located in WWTPs?

      Q4: What are the most important characteristic parameters to be measured for the activated sludge process?

      Q5: What are the most important operating parameters in this process?

      Q6: What is the HRT and how it is calculated?

      - Submit your answers on Moodle by (06/06/2024).
