Industrial odour control with ozone for exhaust and flue applications

Ozone is powerful, but the application must be controlled. Correct dosing, contact time, extraction design, ozone monitoring and off-gas safety are central to any odour control project.

Application overview

When ozone can be useful for odour control

Ozone is a strong oxidant that can react with many odour-causing compounds. In the right application, it can be used to support odour reduction in exhaust air, flues, ductwork, enclosed spaces and selected industrial processes. Ozcon supplies ozone generators for industrial and commercial applications where controlled ozone production is required.

However, ozone odour control should not be treated as a simple plug-in solution. Performance depends on the contaminant type, airflow rate, humidity, temperature, contact time, mixing, safety controls and whether people may be exposed.

Industrial exhaust and process odour applications
Duct-mounted ozone treatment for controlled air streams
Shock treatment for unoccupied spaces after odour events
Odour control support for food, waste, rendering, wastewater and production environments

Not every odour problem should be treated the same way.

Some applications need ozone injection. Others may need filtration, carbon, UV-O, wet scrubbing, biological treatment or a combined approach. The starting point is always the process and the odour source.

Treatment routes

Ozone odour control system options

The correct route depends on whether the problem is a continuous exhaust stream, a ducted kitchen or process application, or a one-off odour event in an enclosed and unoccupied space.

Industrial exhaust

Flue and Process Odour Control

Ozone injection may be considered for selected industrial exhaust streams where odour compounds can be oxidised within a controlled duct, stack or treatment zone.

Duct mounted

Controlled Ozone Injection

Duct-mounted systems can dose ozone into extraction or ventilation systems where airflow, contact time and safety controls can be properly managed.

Ozone odour control for industrial and dairy processing applications

Site specific

Industrial Process Applications

Food, wastewater, rendering, dairy and production odours often need a site-specific approach, based on process conditions and odour chemistry.

Typical odour sources

Food processing Wastewater Rendering Pet food Dairy Rubber & plastics Flue gas Kitchen extract

How it works

Ozone reduces odour by oxidation, not by masking it

Ozone reacts with many organic and inorganic odour-causing compounds. The aim is to chemically alter or break down the compounds responsible for nuisance odour, rather than covering the smell with another fragrance.

Source The odour source, process and exhaust conditions are identified before equipment is selected.

Dosing Ozone is introduced in a controlled way, based on airflow, contaminant load and available contact time.

Reaction Oxidation takes place within the duct, stack, treatment zone or enclosed space.

Safety Residual ozone must be managed through safe design, monitoring, interlocks and appropriate destruction where needed.

Controlled ozone equipment for odour treatment

Important safety point

Ozone treatment must be controlled and designed around occupancy, extraction, monitoring and residual ozone management. Shock treatment should only be used in unoccupied spaces and continuous treatment requires appropriate controls.

Project information

What we need to assess an ozone odour control project

A practical review starts with the odour source and the air stream. Photos, process details and airflow information are often more useful than a general description of the smell.

Odour source and process type
Airflow rate and duct size
Temperature and humidity
Operating hours and peak load
Available contact time or duct length
Discharge location and nearby receptors
Existing filtration or treatment stages
Any complaint, permit or planning context
