Sources and treatments of ammonia odors - BioAir

Probably the most effective ammonia odor treatment is via the application of acids in an ammonia scrubber. That’s because ammonia and its derivatives are slightly basic and could readily be removed through solution in acidic conditions. Phosphoric acid (H 3 PO 4) and sulfuric acid (H 2 SO 4) are the most common acids used in ammonia scrubbers.
