Nitrate Removal in Anaerobic digestion
Typically, my experience is that wastewater solids sent to anaerobic digesters contain relatively little nitrates . I'm looking for information on what type of nitrate removal rate could be expected from anaerobic digestion if an industrial waste with a high nitrate concentration were introduced into the digesters from an outside industrial source.
I would expect the nitrate to be broken down and the nitrogen released. One concern might be an increase in nitrogen in the digester gas. Being that you don't mention a carbon source in the waste I wonder what the benefit would be to send this waste to the anaerobic digester.
