Product Overview This modular biological air scrubber is intended for exhaust air treatment in commercial pig houses. Ventilation fans direct barn air through a connected air corridor and a wetted filter bed, where dust is captured and microorganisms on the media help break down odor compounds and transform ammonia. The module arrangement can be planned around the ventilation duty, building layout and available service space. It is suitable for new pig farm construction and selected retrofit projects.
Key Features
  • Modular configuration for different pig house capacities and exhaust air layouts.
  • Large wetted media surface for contact between exhaust air, recirculating water and biological growth.
  • Dedicated access to pumps, pipework, instrumentation and controls for routine inspection.
  • Corrosion-resistant enclosure and water-contact components specified according to project conditions.
  • Integration with livestock ventilation systems, air corridors and steel structure pig house projects.
Structural Components Typical assemblies include a modular enclosure, exhaust air inlet, air distribution section, biological filter media, spray headers, recirculation sump and pump, water supply and blowdown connections, mist eliminator, inspection access and control cabinet. The final component schedule is confirmed during engineering design.
Working Principle Pig house exhaust fans convey air into the scrubber through a sealed connection. Water is distributed over the filter media to maintain a moist contact surface. Particles and soluble compounds transfer into the circulating water, while the established microbial community contributes to odor treatment and ammonia conversion. A mist eliminator limits droplet carryover before treated air is discharged. Water quality, blowdown and media condition require ongoing management to support stable operation.
Technical Specifications
  • Design airflow and number of modules: According to project requirements
  • Enclosure size and connection arrangement: Customizable
  • Filter media, spray system and pump selection: Available upon request
  • Electrical supply and control interface: According to project requirements
  • Climate protection and material selection: Designed according to local climate and farm conditions
  • Emission performance: Subject to inlet conditions, operating settings and project-specific verification
Applications Commercial finishing barns, sow houses, piglet rearing facilities and integrated swine production sites with mechanically ventilated exhaust air. The system can be incorporated into new livestock buildings or evaluated for existing houses where the ventilation capacity, structural interfaces and installation space permit.
Customization Options Module quantity, enclosure dimensions, inlet and outlet orientation, service access, water connections and control interfaces can be coordinated with the pig house layout. Design inputs should include fan airflow, operating schedule, expected dust loading, water availability, discharge requirements and local emission targets.
Installation & Maintenance Modules are positioned on an engineered foundation and connected to the barn exhaust corridor, power supply, fresh water and blowdown system. Installation planning should allow for lifting access, drainage, weather protection and safe maintenance clearance. Routine work includes checking spray coverage, pump operation, pressure drop, water condition, instrumentation and filter media.
Product FAQ

Can the system be added to an existing pig house?
Yes, subject to an assessment of the exhaust fan arrangement, available space, building structure and utility connections.

How is the required capacity determined?
Sizing is based on the design exhaust airflow, ventilation operating profile and project-specific treatment objectives.

Does biological treatment require maintenance?
Yes. The water circuit, spray distribution, instrumentation and media must be inspected and maintained to support biological activity.
