How to design MBBR and ASP system with nitrification and denitrification process in a Waste water treatment system?

Dear friends,   I need inputs for designing Waste water system. The Waste water details are -  flow 500 m3/day, BOD 300 ppm,  T otal Kjeldahl Nitrogen (TKN) 400 ppm and NH3 300 ppm. We need to have treated results as BOD 10 ppm and NH3 10 ppm.   We want to go for following methods:   1. Denitrification (Anoxic tank) + BOD removal (Aeration tank) + Nitrification for nitrogen removal tank ----- in Activated Sludge Process (ASP)   2. Denitrification (Anoxic tank)+ BOD removal (Aeration tank) + Nitrification for nitrogen removal tank-----in Moving Bed Bio Reactor (MBBR) I need inputs for the following, 1. How to reduce  BOD, TKN, NH3 levels? 2. How to calculate the MBBR and Nitrification tank volume ? 3. How to estimate required tank volume for ASP process and nitrification ? 4. How to calculate the air requirement for the process ?   I need to know all these design calculations for my existing work.   Thank you.
