Ammonia & Hydrogen Sulfide Gas Control
Control ammonia (NH₃), hydrogen sulfide (H₂S) and related odor gases in livestock, waste, sewage and industrial environments using targeted gas-phase filtration and source-focused solutions.

Ammonia and hydrogen sulfide can occur in animal facilities, manure handling, wastewater, sewage and waste environments. The source and concentration should be understood before selecting treatment.
Ammonia — NH₃
Ammonia is a pungent gas commonly associated with animal waste, manure, urine, fertiliser and some industrial processes.
Common sources: livestock • poultry • manure • waste • fertiliserHydrogen Sulfide — H₂S
Hydrogen sulfide is associated with decomposition under low-oxygen conditions and can occur in sewage, wastewater, manure and organic waste systems.
Common sources: sewage • wastewater • manure • sludge • organic wasteWhere NH₃ and H₂S Control May Be Needed
These gases can occur across agricultural, municipal, commercial and industrial environments.
Livestock Farms
Animal housing, urine and manure can create significant ammonia odor loads.
Poultry Facilities
Litter and manure accumulation can contribute to elevated ammonia levels.
Sewage & Wastewater
Wastewater and sludge can release H₂S and other decomposition gases.
Industrial & Waste Areas
Waste handling and some processes can generate sulfur or ammonia-based gases.
Gas Control Starts With Measurement and Source Identification
Odor alone is not a reliable way to determine gas concentration. The application should be assessed before designing a filtration system.
Identify the Source
Determine whether the gas originates from manure, sewage, waste, drains or a process.
Identify the Gas
Determine whether NH₃, H₂S or multiple gas-phase contaminants are involved.
Evaluate Airflow
Review ventilation, humidity, air volume and how contaminated air moves.
Select the Media
Match the filtration media, bed depth and airflow to the target gas and application.
Targeted Media for Ammonia and Sulfur Gases
General odor filters are not always suitable for high gas loads. Media should be selected according to the target contaminant and operating conditions.
Specialised Carbon
Impregnated activated carbon can be selected for targeted removal of hydrogen sulfide and other sulfur compounds.
Ammonia Media
Selected adsorbent or chemically treated media can be designed specifically for ammonia capture.
Zeolite
Selected zeolite media can adsorb ammonia and may be useful in suitable lower-load applications.
Multi-Stage Filtration
Where multiple gases are present, different media can be combined to target ammonia, sulfur compounds and VOCs.
Gas Control Across Agriculture, Waste and Industry
Strong odor can indicate a gas-control problem — but smell is not a gas monitor.
For environments where ammonia or hydrogen sulfide may reach hazardous concentrations, appropriate gas detection, ventilation and occupational safety controls are essential. Filtration should be designed as part of the overall control strategy.
