Managing Emissions In Wastewater
Wastewater treatment facilities are among the most odour-sensitive industrial environments. The anaerobic decomposition of organic matter produces a range of problematic compounds, including hydrogen sulphide (H2S), ammonia (NH3), mercaptans, amines, indoles, skatoles and other volatile organic compounds (VOCs). These odours typically arise from sludge digestion, primary sedimentation, aeration and dewatering stages.
These emissions are not just unpleasant. They pose serious challenges for worker safety, regulatory compliance and community relations.
At Probe Industries, we deliver proven odour control solutions tailored for the wastewater sector. Our biodegradable, non-toxic chemical treatments and automated misting systems improve air quality on site while helping facilities meet local and national environmental standards.
Customer Scrubber Systems
Engineered Upon Request
When infrastructure permits, the most robust method of odour control involves capturing and treating contaminated air through a chemical scrubber system. At Probe Industries, we offer custom-designed chemical wet scrubbers tailored to the specific demands of wastewater treatment facilities.
These systems operate by drawing odorous air through a packed bed where it contracts a recirculating liquid solution, typically water adjusted to the appropriate pH and supplemented with oxidising agents. This process effectively absorbs and neutralises odorous compounds such as hydrogen sulphide, ammonia and VOCs.
Our scrubbers are engineered for seamless integration into existing ductwork, tanks, or containment structures, ensuring efficient removal of high-load gases before they reach the surrounding environment.
While scrubbers represent the gold standard in odour abatement, they may not always be feasible due to spatial constraints or budget considerations. In such cases, we provide targeted alternatives, including ProActive for direct injection into wastewater streams, AiroPure® for misted air treatment and our automated misting systems like ProFog™ and ProAir™ for scalable atmospheric control. These solutions offer flexibility and effectiveness, ensuring optimal odour management tailored to the specific needs of your facility.
Proven Alternatives For Targeted Wastewater Odour Control
ProActive™
Pre-Emission Odour Treatment For Sludge
Injected directly into sludge or effluent tanks, ProActive™ neutralises odours within the liquid waste stream before they are released into the air. It is especially effective against sulphur-based compounds and integrates easily into existing dosing systems.
AiroPure®
Advanced Air Treatment
Where emissions are already airborne, AiroPure® delivers molecular-level odour destruction. it is ideal for use in misting systems, headspace treatments, or direct spray over open tanks and is effective against the full spectrum of odours found in wastewater, including amines and VOCs.
ProFog™ And ProAir™
Automated Misting For Airborne Control
Our misting systems provide coverage for odorous zones across treatment infrastructure. ProFog™ disperses a fine mist ideal for open tanks and clarifiers, while ProAir™ delivers ultra-fine fog for more contained or sensitive spaces. Both systems offer low-maintenance, automated operation and can be paired with AiroPure® for maximum effect.
Typical Applications
There are many applications where our solutions are most effective. They include:
- Effluent tanks and settlement basins.
- Sludge digestion and dewatering systems.
- Primary clarifiers and aeration tanks.
- Headspace enclosures and odour extraction ducts.
- Pumping stations, lagoons and storm drains.
Built For Compliance And Operational Simplicity
Odour control is not optional in today’s regulatory climate. Our solutions help wastewater operators meet air quality standards, avoid complaints and create safer working conditions. Whether through fully engineered scrubber systems or targeted chemical and misting interventions, Probe Industries delivers reliable, sustainable control.
