Odor Control

Most offensive odors produced in wastewater are the gaseous byproduct of decomposed organic matter. The most common of these is hydrogen sulfide, commonly referred to by its chemical formula H2S, which is formed from the anaerobic degradation of organic matter containing sulfur or from mineral sulfates and sulfites. Hydrogen sulfide is known for its rotten egg smell and can adversely impact human health at levels above 10 ppm. Odor in sewer lines, collection points, treatment plants, and ponds can lead to public complaints and reduces aesthetic value. One means of treating odors, including H2S, is to prevent the water from going anaerobic by increasing dissolved oxygen (DO) or oxidation reduction potential (ORP) using air, oxygen or other oxidants. Moleaer's effective gas-injection technology delivers a high volume of air or oxygen nanobubbles, efficiently maintaining DO and preventing the anaerobic conditions that lead to odorous compound formation.
