ETP Odor Control Unit

An ETP Odor Control Unit is an essential system designed to eliminate foul and corrosive gases generated during effluent treatment, ensuring a cleaner and safer working environment. During biological and chemical processes, gases such as hydrogen sulfide (H₂S), ammonia, mercaptans and various VOCs are released, which not only create strong odors but also corrode equipment, pose health risks and trigger community complaints. To manage these challenges, odor control units are engineered using either advanced dry media filtration or chemical wet scrubbing. Dry systems use activated carbon or impregnated catalytic media to adsorb and neutralize contaminants, while wet scrubbers rely on gas–liquid mass transfer and chemical reactions to convert harmful gases into harmless byproducts. These units are constructed using corrosion-resistant materials like FRP, PP or HDPE, enabling continuous 24/7 operation even in harsh, high-humidity environments. Designed for long service life with minimal maintenance, they ensure high odor removal efficiency of up to 99.9% while maintaining a low system pressure drop and optimizing blower energy consumption. Their reliability makes them suitable for installations at pumping stations, equalization tanks, aeration basins, sludge handling zones, manholes and ETP vent points where odor generation is frequent. By effectively capturing and neutralizing odorous compounds at the source, an ETP Odor Control Unit helps maintain workplace hygiene, extend equipment lifespan, prevent corrosion-induced failures, and support full compliance with CPCB and state pollution control norms. As industrial and municipal facilities continue to face strict odor regulations and increased public sensitivity, these systems play a vital role in ensuring sustainable, complaint-free, and environmentally responsible operations.
