Phosphoric acid (H 3 PO 4) and sulfuric acid (H 2 SO 4) are the most common acids used in ammonia scrubbers. They’re mixed with water so that ammonia compounds transfer out of the air phase and into the water phase prior to the chemical reaction. Ammonium salts are the byproduct. These systems are colloquially known as “wet scrubbers.” BioAir recommends chemical ammonia treatment via its Qimi® …
