Product Overview This biological odor treatment system is designed for process air collected from enclosed manure composting, livestock waste handling, and related farm facilities. A fan directs the extracted air through an air distribution zone and a moist biological filter bed. The system can be integrated with a steel structure composting building, enclosed receiving area, or other project-specific ventilation arrangement.
Key Features
  • Biological treatment of collected odor-bearing air without routine chemical dosing in the filter bed.
  • Air distribution beneath the media helps promote consistent contact across the bed.
  • Modular or site-built layouts can be planned around available space and required airflow.
  • Moisture management supports the microbial activity needed for stable operation.
  • Access for inspection, drainage maintenance, and eventual media replacement can be incorporated into the layout.
Structural Components A typical arrangement includes an exhaust fan, collection ductwork, inlet manifold, air distribution plenum, media support, biological filter media, moisture supply, drainage provisions, and inspection access. The containment structure and corrosion-resistant material selection are determined according to project requirements. Air preconditioning may be specified where dust, aerosols, temperature, or inlet concentrations require it.
Working Principle Odorous air is extracted from the composting or waste handling area and distributed below the filter bed. As it passes through moist media, odor compounds transfer to the biofilm and are biologically degraded by microorganisms. Airflow distribution, media condition, and adequate moisture are central to effective operation.
Technical Specifications
  • Design airflow: According to project requirements
  • Filter bed area and media depth: Customizable
  • Media type and replacement plan: Available upon request
  • Fan, duct, and plenum arrangement: According to project requirements
  • Moisture and drainage design: Designed according to local climate and farm conditions
  • Controls and monitoring: Customizable

Final sizing and any odor reduction target require inlet air data, operating conditions, and a project-specific engineering assessment.

Applications Commercial pig farm manure composting buildings, enclosed manure receiving areas, livestock waste processing facilities, compost maturation areas with collected exhaust air, and agricultural organic waste treatment projects.
Customization Options The bed layout, enclosure, duct connections, fan arrangement, controls, and maintenance access can be coordinated with the farm ventilation design and steel structure building drawings. Multiple filter cells may be considered for larger or phased projects. Configuration is subject to site space, climate, inlet air characteristics, and applicable discharge requirements.
Installation & Maintenance Install the filter on a suitably engineered foundation with access to power, water, drainage, and the composting building exhaust duct. During operation, inspect the fan and ductwork, check media moisture and airflow resistance, keep distribution and drainage paths clear, and assess the media for settling or channeling. Replace or replenish media according to its condition and the project maintenance plan.
Product FAQ

Can the biofilter connect to an existing composting building?
Yes. The connection and fan duty should be engineered around the building's exhaust airflow, duct routing, and available installation space.

Does the filter media need moisture?
Yes. The biological bed must be kept within a suitable moisture range for microbial activity while avoiding waterlogging.

What information is needed for a proposal?
Provide the process description, exhaust airflow, inlet air conditions, site layout, local climate, and applicable odor or emissions requirements.
