Paramount undertakes design and manufacture of complete chemical treatment systems for removal of Odour from exhaust gases. While in some applications, a packed bed scrubber is used, combined with a chemical; oxidant or adsorbant, to remove the odour causing compounds, in other cases, chemical oxidation is combined with either alkaline or acidic absorption to accomplish complete odour reduction. In the most difficult situations, however, chemical oxidation is combined with both acidic and alkaline absorption to accomplish the necessary odour reduction.

Oxidizing agents normally used include ozone, potassium permanganate, hydrogen peroxide and sodium hypochlorite. Sodium hydroxide or soda ash (Sodium carbonate) is used as the alkaline absorber, while Sulphuric acid is normally used as the acidic scrubbing agent. In certain cases, however, hydrochloric, nitric, phosphoric or acetic acids are also used.
