Product Details
Eco-Friendly Eco-Biofiltration Systems for Industrial Odor Abatement
Our Biological Deodorization Boxes (Biofilters) deliver an eco-friendly, sustainable, and highly effective solution for neutralizing odorous gas compounds and volatile organic contaminants. By leveraging natural microbial degradation inside a controlled bio-media environment, these systems convert harmful reduced-sulfur and nitrogen compounds into odorless inorganic byproducts without generating secondary chemical waste.
Key Features & Advantages
- Chemical-Free Operation: Eliminates the need for expensive chemical reagents, reducing operational hazards and recurring chemical purchase costs.
- High Hydrogen Sulfide & Ammonia Removal: Achieves up to 99% removal efficiency for H2S, mercaptans, amines, ammonia, and VOC odor compounds.
- Long-Life Inorganic/Organic Bio-Media: Engineered bio-packing media provides high moisture retention, structural stability, and low degradation over multi-year operational cycles.
- Integrated Humidification & Irrigation: Automatic water/nutrient spraying system maintains optimal temperature and moisture levels for healthy microbial colonies.
- Corrosion-Proof Housing: Constructed using premium FRP or PP materials to handle highly acidic and humid bio-reaction environments.
Working Principle
- Pre-Conditioning: Raw odorous air enters a humidification section where water sprays saturate the gas stream to 100% relative humidity and remove particulates.
- Biofiltration Bed: The saturated gas passes through a specialized bio-packing layer populated with active microbial cultures.
- Biological Degradation: Microorganisms absorb gas-phase contaminants into their liquid biofilm and metabolize them into CO2, H2O, and mineral salts.
- Clean Exhaust: Purified, odorless air passes through mist separation before being discharged safely into the atmosphere.
