STP Odor Control Unit

Apzem STP Odor Control Units are purpose-built to eliminate unpleasant and corrosive gases generated in Sewage Treatment Plants (STPs), especially around inlet chambers, aeration tanks, sludge handling zones, and enclosed treatment areas. STPs commonly release gases such as hydrogen sulfide (H₂S), ammonia, mercaptans, and volatile organic compounds (VOCs), which not only create odor nuisance but also accelerate corrosion of equipment and pose health risks to personnel and surrounding communities. Apzem’s systems treat the extracted foul air using advanced dry media adsorption or multi-stage chemical wet scrubbing, effectively neutralizing odor-causing and reactive compounds before safe discharge. Constructed using corrosion-resistant FRP, PP, HDPE or MS-FRP materials, the units are designed for harsh wastewater environments and continuous 24/7 operation. With odor removal efficiency up to 99.9%, low pressure drop, optimized blower sizing, and minimal maintenance requirements, Apzem odor control solutions ensure reliable and energy-efficient performance throughout the plant life cycle. By improving workplace hygiene, reducing odor-related complaints, preventing H₂S-induced corrosion, and supporting compliance with environmental standards, Apzem’s STP Odor Control Units provide municipalities, commercial facilities, and industrial wastewater treatment plants with a dependable and long-lasting air treatment solution tailored to site-specific conditions.
