You will need to determine incoming COD, this will be a function of the conditions associated with the generation of the wastewater, is it domestic, industrial etc. For domestic you should also relate to local conditions as this has influence, is it combined sewer/stormwater, high/low income region etc all have influence
then you need to fix the effluent target limit
Metcalf &Eddy publication will give you some overall references on how or what to select for your specific application
contact me if you require more detailed support

Thank. I will give you parameter at inlet and requirement of discharge point:
Inlet: capacity = 400m3, COD = 15.000mg/l, BOD=10.000mg/l, TSS =600mg/l. Oil and grease = 250 mg/l, total N = 7mg/l, total P =10mg/l.
Discharge: COD = < 75mg/l, BOD
