Q3.1) If an unaerated mass fraction fX1 is created at the beginning of the aerobic reactor, can the plant be able to comply with a TNeff concentration of less than 10 mg/L? If so, what fx1 do you suggest to implement to comply with the upcoming TNeff concentration of less than 10 mg/L?

Q3.2) If the plant cannot comply with the TNeff concentration of less than 10 mg/L, what modifications do you suggest to implement to meet the effluent discharge limit of 10 mgN/L?

Q3.3) What will be the selected a-recycle ratio?

Q3.4) What will be the expected TNeff concentration that could meet the upcoming TNeff discharge standard of less than 10 mg N/L?

Q3.5) If the plant is further optimized, what will be the minimum a-recycle ratio that could contribute to meet the upcoming TNeff discharge standard of less than 10 mg N/L while decreasing the internal recirculation flowrates?
