This system is commonly used in wastewater treatment plants, municipal solid waste transfer stations, sludge dewatering rooms, composting facilities, and chemical or food processing industries where malodorous gases are generated.
Working Principle:
Pre-treatment: Odorous air is first filtered and humidified to ensure optimal conditions for microbial activity.
Biological Degradation: The air passes through a biological filter bed (often filled with organic packing such as wood chips, compost, or synthetic media), which is colonized by microbial communities.
Odor Removal: Microorganisms metabolize the odorous compounds as a nutrient source, breaking them down into harmless byproducts such as CO₂, water, and biomass.
Exhaust: The purified air is discharged, typically via a stack or vent, meeting environmental emission standards.
Advantages:
High odor removal efficiency (up to 95%+)
No secondary pollution or harmful residues
Low operating costs and energy consumption
Long-term, stable performance with proper microbial management
Suitable for continuous and large-volume odor treatment
The Biological Deodorization System is a sustainable solution for odor control and is increasingly favored in industries aiming to reduce their environmental impact.
