Pollutant Guide
Animal Room Pollutant Concentration Reference
Typical pollutant levels in different animal facility types. Understanding your pollutant profile is the first step to effective treatment.
| Pollutant | Source | Typical Concentration | Health Threshold | Treatment Stage |
|---|---|---|---|---|
| Ammonia (NH3) | Urine decomposition | 5-50 ppm | 25 ppm (animal comfort) | Acidic spray tower |
| Hydrogen Sulfide (H2S) | Fecal matter | 0.5-10 ppm | 1 ppm (odor threshold) | Alkaline spray + UV |
| Volatile Organic Compounds | Feed, bedding, feces | 2-20 mg/m3 | Varies by compound | UV photolysis + carbon |
| Particulate Matter (PM) | Bedding, dander, feed | 0.1-5 mg/m3 | 0.1 mg/m3 (lab grade) | Pre-filter (G4/F8/HEPA) |
| Airborne Pathogens | Animals, waste | Varies | Zero tolerance | UV-C sterilization |
| Odor (composite) | Mixed sources | 500-3000 dilution | 200 (nuisance level) | Multi-stage combined |
The Challenge
What Makes Animal Room Air Different
Animal facilities generate unique pollutants that standard ventilation systems cannot handle alone.
Ammonia (NH3)
Released from urine decomposition by urease-producing bacteria. Causes respiratory stress, eye irritation, and reduced research quality at concentrations above 25 ppm.
Critical: Above 25 ppmHydrogen Sulfide (H2S)
Produced from fecal matter by sulfate-reducing bacteria. Toxic even at low concentrations — detectable by human nose at 0.0005 ppm, causing immediate odor complaints.
Toxic: Above 1 ppmAllergens & Pathogens
Animal dander, fur, and fecal particles carry allergens and potentially dangerous pathogens. Airborne transmission is a significant biosafety risk in research facilities.

Our Solution
Four-Stage Treatment Process
Each stage targets specific pollutants. The combination delivers complete air purification that no single technology can achieve alone.
1
Pre-Filter Stage
G4 or F8 pocket filter captures dust, dander, bedding particles, and large particulate matter. Protects downstream stages from clogging. Optional HEPA for lab-grade filtration.
2
Acidic Spray Tower
Dilute sulfuric acid or citric acid solution absorbs ammonia (NH3) through chemical reaction: 2NH3 + H2SO4 → (NH4)2SO4. Achieves 90%+ ammonia removal. Also captures water-soluble odor compounds.
3
UV Photolysis Reactor
UV-C light at 185nm and 254nm destroys molecular bonds in odor compounds and damages pathogen DNA/RNA. Breaks down H2S, volatile organic sulfides, and airborne microorganisms.
4
Activated Carbon Polisher
Final-stage carbon bed adsorbs residual odor compounds and trace VOCs. Ensures exhaust air is clean, odor-free, and safe for surrounding environments and neighboring communities.
Ventilation Guide
Animal Room Air Change Rate Reference
Recommended ventilation rates for different animal facility types. The treatment system must be sized to match your facility’s air change requirements.
| Facility Type | Air Changes/Hour (ACH) | Typical Air Volume | Key Pollutant | System Recommendation |
|---|---|---|---|---|
| Research Vivarium (rodents) | 10-15 ACH | 500-3,000 m3/h | NH3, allergens | 4-stage with HEPA |
| Dog / Cat Housing | 8-12 ACH | 1,000-5,000 m3/h | NH3, odor, dander | 4-stage standard |
| Rabbit Facility | 10-15 ACH | 500-3,000 m3/h | NH3, allergens | 4-stage with HEPA |
| Poultry Farm | 4-8 ACH | 5,000-20,000 m3/h | NH3, dust, H2S | 3-stage heavy-duty |
| Swine Farm | 5-10 ACH | 5,000-20,000 m3/h | NH3, H2S, odor | 3-stage heavy-duty |
| Veterinary Clinic | 8-12 ACH | 500-2,000 m3/h | Odor, pathogens | 4-stage compact |

What Is
What Is Animal Room Waste Gas Treatment?
Animal room waste gas treatment is a specialized air purification system designed to treat exhaust air from laboratory animal facilities (vivariums), breeding centers, and farm animal housing. These facilities generate unique pollutants — ammonia from urine decomposition, hydrogen sulfide from fecal matter, allergens from dander, and potentially airborne pathogens — that standard ventilation alone cannot address.
The system uses a multi-stage approach: pre-filtration for dust and dander, an acidic spray tower to absorb ammonia through chemical reaction, UV photolysis to destroy odor molecules and damage pathogen DNA, and activated carbon for final odor polishing. The result is clean exhaust air that protects both animal welfare and the surrounding environment.
Unlike general industrial air treatment, animal room systems must meet specific standards for pathogen control, animal environment quality, and research integrity. The system must be carefully sized to match the facility’s air change rate requirements while maintaining consistent treatment performance across varying pollutant loads.

FAQ
Frequently Asked Questions
Common questions about animal room waste gas treatment systems for vivarium and breeding facility exhaust treatment.
What ammonia removal efficiency can I expect?
Our systems typically achieve 90%+ ammonia removal with the acidic spray stage. The exact efficiency depends on inlet concentration and contact time. For laboratory vivariums with moderate ammonia levels, we can typically reduce outlet NH3 to well below 25 ppm — the threshold for animal comfort and health.
Does the system kill airborne pathogens?
The UV photolysis stage significantly reduces airborne pathogens by damaging their DNA/RNA with high-energy UV-C light at 254nm. While not a sterile solution, it provides an important additional layer of biosafety. For specific pathogen concerns, we can design enhanced UV configurations or add HEPA (H13/H14) filtration stages.
How much maintenance does the system require?
Routine maintenance includes: pre-filter replacement every 1-3 months, spray solution pH check and adjustment weekly, UV lamp replacement every 8,000-10,000 hours, and activated carbon replacement every 6-12 months. Our systems include automated monitoring with alerts when maintenance is needed — so you never have to guess.
Can the system be integrated with our building HVAC?
Yes, our systems are designed to integrate with existing HVAC exhaust systems. We provide detailed ductwork specifications and can work with your mechanical engineer to ensure proper airflow balance. The system can also include pressure monitoring and interlock with the building management system (BMS).
