There is plenty of literature on denitrification by alternating between
aerobic and anaerobic treatment stages, or by using an anaerobic reactor.
The wastewater would have to be characterized to screen for toxics and
interferences, and whether an additional carbon source is needed (e.g.,

Subject: Bioremediation or inorganic treatment?
I'm dealing with a manufacturer that has a waste stream with high
nitrites and nitrates. Can anyone advise on a biodegradation (bug)
system/vendor this company might use in their wastewater ponds
(permitted industrial ponds)? Their ponds were undersized and they
are looking at biotreatment to reduce the nitrate levels so that some
of this wastewater can be sent to their local POTW.
I would also like to know if there is a chemical WWT (wastewater
treatment) option here?
the wastewater stream is about 2500g/d, 4 days a week; wastewater
also has charcoal in it. Have looked at land application and
commercial WWT options already.
I will be working with this company on an alternative cleaning
process (dry cleanup for pre-clean) and ways to reduce contaminate
loading, so will be looking at P2 options.
If you have experience with de-nitrification systems please email me
