Odor Sources
Common Industrial Odor Compounds
Different industries produce different odorous compounds. Understanding your odor source is the first step to effective treatment.
| Odor Compound | Chemical Formula | Typical Source | Odor Threshold | Treatment Method |
|---|---|---|---|---|
| Hydrogen Sulfide | H2S | Waste treatment, food processing | 0.0005 ppm | Alkaline spray + carbon |
| Ammonia | NH3 | Feed mills, composting | 0.03 ppm | Acidic spray + carbon |
| Methyl Mercaptan | CH3SH | Pulp, rendering | 0.0001 ppm | UV + alkaline spray |
| Trimethylamine | (CH3)3N | Fish processing, chemical | 0.0004 ppm | Acidic spray + UV |
| Volatile Organic Sulfides | VOSCs | Slaughterhouse, rendering | varies | UV + carbon |
| VOCs (general) | Various | Chemical, coating, printing | varies | UV + activated carbon |
How It Works
Multi-Stage Odor Treatment Process
Each stage targets different odor compounds. The combination delivers complete odor elimination that no single technology can achieve alone.

See how our multi-stage deodorization system solved a persistent odor complaint problem.
Case Study
Food Additive Production Facility
Challenge
A food additive production facility emitted strong odorous gas containing hydrogen sulfide (H2S), ammonia (NH3), and volatile organic sulfides. Nearby residential areas filed multiple odor complaints. The odor concentration exceeded 2,000 on the dilution factor scale.
Solution
We designed a three-stage deodorization system: (1) alkaline spray tower to remove H2S and acid gases, (2) UV photolysis reactor to break down organic sulfides, and (3) activated carbon bed for final polishing. Total air volume: 15,000 m3/h.

What Is
What Is a Spray Deodorization System?
A spray deodorization system is a multi-stage industrial air treatment solution designed to remove odorous compounds from industrial exhaust gas. Unlike single-technology systems, it combines spray absorption, UV photolysis, and activated carbon adsorption in a tailored sequence to tackle complex odor problems that no single technology can solve alone.
The system works by first passing odorous gas through a spray tower, where water or a chemical solution absorbs water-soluble odor compounds such as H2S and NH3. Then UV photolysis breaks down organic odor molecules that resist spray treatment, and finally activated carbon captures any remaining trace compounds. The result is clean, odor-free air that meets emission standards and eliminates neighbor complaints.
These systems are custom-designed for each application — every odor source is unique, and the treatment configuration must match the specific compounds, concentrations, and air volumes involved. We analyze your gas composition and design the optimal combination of stages.
Key Benefits
Why Choose Multi-Stage Deodorization
Four advantages that make multi-stage systems the most reliable odor control solution.
01
85-95% Odor Removal
Multi-stage treatment achieves 85-95% odor reduction — far exceeding what any single technology can deliver. Effectively eliminates nuisance complaints from surrounding communities and meets regulatory odor emission standards.
02
Handles Complex Mixed Odors
Industrial odors often contain sulfides, ammonia, VOCs, and organic compounds simultaneously. Multi-stage systems tackle each compound type with the appropriate technology — no single method can do this alone.
03
Custom-Tailored Configuration
Every system is designed for your specific odor source. We select the right combination of spray liquid, UV lamp configuration, and carbon type based on your gas analysis. No one-size-fits-all approach.
04
Proven in Real Projects
Backed by successful installations at food factories, feed mills, waste treatment plants, and chemical processing facilities — all with verified, long-term odor reduction results and zero neighbor complaints.

FAQ
Frequently Asked Questions
Common questions about spray deodorization systems for industrial odor control.
How do you determine which deodorization system I need?
We start by understanding your odor source — what industry, what production process, and what the main odor compounds are. If you have a gas analysis report, that is ideal. Otherwise, we can recommend based on similar projects we have completed. We will design a system with the right number of stages and technologies for your specific odor problem.
How much does a spray deodorization system cost?
Cost depends on air volume, number of treatment stages, and materials. A basic 2-stage system for 5,000 m3/h starts around a few thousand dollars. A large 3-4 stage system for 50,000 m3/h is a more significant investment. Contact us with your details and we will provide a detailed quote within 24 hours.
What is the difference between spray deodorization and biofiltration?
Spray deodorization uses chemical or plant-based solutions to absorb and neutralize odors — it is compact and fast-acting. Biofiltration uses microorganisms to break down odor compounds — it is more effective on certain compounds but requires more space and time to establish. Many systems combine both for maximum effectiveness.
How long does it take to see results after installation?
Spray and UV stages work immediately — you will notice odor reduction as soon as the system is turned on. If a biofilter is included, it takes 2-4 weeks for the microorganisms to fully establish and reach peak efficiency. We provide commissioning support to ensure everything works correctly from day one.
