I need information of methanol requirement for 1 MGD Waste Water Treatment
Assuming that you are adding the methanol for post-dentrification then the answer is that no one knows, until you release information of the nitrate entering the post-denitrification tank and the target effluent nitrate.
The quantity is defined by stoichiometry; you will need to check that the contact time is long enough that the kinetics are not the limiting factor. The contact time will be affected to some extent by the nitrate and biomass concentration.
Look at this

Thankyou Jeremy, I was looking the average nitrate content in USA, its around 50mg/L. Can I derive the methanol requirement from that information just to look for the average methanol requirement
The link will give you the information, so yes.
50 mg/l nitrate seems high for the USA (ammonia is usually 40 mg/l or less as NH3-N) - check if they are quoting the concentration as NO3-N or as NO3. 50 mg/l as NO3 is c. 11.3 mg/l as NO3-N.
