So after being taught by the industry that ammonia/nitrates were the culprits for high chlorine demand for so many years working in the industry, I have finally learned the truth.
My professor at the University of Florida informed me that it is actually the nitrites that exert chlorine demand in their transient state between ammonia and becoming nitrates. Nitrites are NO2, and in order for them to convert to Nitrates NO3, they need oxygen. Where do they get that oxygen? They strip it off NaOCl.
Just thought I'd share if anybody was interested to hear that.
