A sewage odour control unit is an essential system used in wastewater treatment plants, STPs, industrial setups, and even homes to eliminate foul smells caused by gases like hydrogen sulfide. These units operate through several technologies such as chemical scrubbers, activated carbon filters, biofilters, or ozone and UV treatment, collectively forming the odor control unit working principle. In India, odour control systems for sewage treatment plants are critical for maintaining public hygiene and regulatory compliance. For STP odour control, specialized chemicals are used to neutralize or break down odor-emitting compounds. Industrial odour control systems are larger in scale and deployed in sectors like food processing and pharmaceuticals. Pump station odor control typically includes sealing, ventilation, and chemical treatments to prevent gas accumulation. At the domestic level, compact odor control units for home help manage smells from septic tanks or private sewage outlets. The unit of measurement for odor is usually odor units per cubic meter (OU/m³) or parts per billion (ppb) for specific gases. In summary, odor control is not a one-size-fits-all solution—it requires a blend of the right equipment, treatment method, and installation environment. For reliable and customized odor control systems, Aaxis Nano offers industry-grade solutions tailored to every need.
✅ What Is Odor Control and Why Is It Important?
Odor control is the process of eliminating or neutralizing foul smells, especially in areas prone to gas emissions due to waste decomposition. Effective odor control:
- Enhances air quality and working conditions.
- Reduces complaints from nearby communities.
- Ensures compliance with pollution control norms.
- Extends the life of sewage and treatment infrastructure.
🧪 STP Odour Control Chemicals: What Are They?
Aaxis Nano offers environment-safe odour control chemicals used in dosing and misting systems to control STP emissions. These:
- Target gases like H₂S and ammonia.
- Are non-corrosive and biodegradable.
- Work seamlessly with our odor control units.
⚙️ Odour Control Unit: Working Principle
Each odor control system at Aaxis Nano operates on one or more of the following principles:
| Technology | Description |
|---|---|
| Chemical Scrubbing | Absorbs H₂S and NH₃ using acidic or alkaline solutions. |
| Activated Carbon Filtration | Captures organic molecules and VOCs. |
| Biofiltration | Uses microbial colonies to break down pollutants biologically. |
| UV/Ozone Treatment | Breaks down gases at a molecular level for instant deodorization. |
