Odour management and treatment technologies: an overview

Area of Science:

• Environmental Engineering
• Industrial Hygiene
• Chemical Engineering

Background:

• Odorous emissions pose significant challenges in industrial settings.
• Existing treatment technologies offer various solutions but often require a broader management strategy.
• A holistic approach is necessary for sustainable industrial odour problem resolution.

Purpose of the Study:

• To outline a systematic approach to industrial odour management.
• To highlight the importance of comprehensive odour assessment and fugitive emission control.
• To guide the selection of appropriate waste gas treatment systems.

Main Methods:

• Review and description of physical, chemical, and biological treatment processes for odorous emissions.
• Emphasis on detailed odour assessment, including identification and characterization of all emission sources.
• Discussion on the capture and treatment of fugitive emissions.
• Presentation of developed test systems for selecting appropriate treatment technologies.

Main Results:

• Various odour treatment options are available, each with specific applications and limitations.
• Fugitive emissions significantly impact overall odour problems and require specific capture strategies.
• A systematic odour assessment is crucial for effective management.
• Test systems aid in selecting suitable waste gas treatment based on gas composition and conditions.

Conclusions:

• Sustainable industrial odour management necessitates a comprehensive strategy beyond treatment systems alone.
• Integrating odour assessment, fugitive emission control, and tailored treatment selection is key.
• The presented systematic approach and test systems support effective odour control solutions.
