Among the various technologies available, activated carbon odour control stands out for its simplicity, reliability, and versatility. It is widely used across sectors due to its effectiveness in removing a broad range of odorous compounds from air streams, particularly in enclosed or localized areas.

This article explores how activated carbon works for odour control, its applications, advantages, limitations, and best practices for operation and maintenance.

What is Activated Carbon?

Activated carbon is a highly porous form of carbon that has been processed to increase its surface area and adsorption capacity. It is typically derived from raw materials such as coal, coconut shells, or wood, and is "activated" through a physical or chemical process that creates an extensive network of microscopic pores.

The high internal surface area—often exceeding 1,000 m² per gram—allows activated carbon to adsorb a wide variety of gases and vapours, including odorous compounds. Adsorption is a process where gas molecules adhere to the surface of the solid media without a chemical reaction, making it a passive but powerful filtration method.

How Activated Carbon Controls Odour

Odour control with activated carbon is based on the physical adsorption of gas molecules onto the surface of the carbon particles. As odorous air passes through a bed or cartridge of activated carbon, the offensive compounds are captured and retained within the media. The treated air that exits the system is significantly reduced in smell.

Activated carbon is particularly effective against:

Hydrogen sulfide (H₂S)

Volatile organic compounds (VOCs)

Mercaptans

Ammonia (to a lesser extent)

Sulfur-containing compounds

In some cases, the carbon can be impregnated with chemical additives (such as potassium hydroxide or phosphoric acid) to enhance its adsorption capacity for specific contaminants or improve reactivity with certain odours.

Applications of Activated Carbon Odour Control

Activated carbon systems are widely used across various industries and facilities where odour emissions need to be controlled. Some common applications include:

Wastewater treatment plants: Odour control at headworks, pump stations, sludge handling, and control rooms.

Chemical-free (in base form): No need for hazardous chemical storage or handling unless chemically impregnated carbon is used.

Limitations and Considerations

While activated carbon is effective, it is not suitable for every odour control scenario. Consider the following limitations:

Media saturation: Once the carbon is saturated, it must be replaced. Breakthrough of odours can occur without warning.

Humidity sensitivity: High humidity can reduce adsorption efficiency, especially for water-soluble gases.

Limited effectiveness for certain compounds: Some odours, such as those from amines or aldehydes, may not adsorb well unless special carbon formulations are used.

Disposal of spent carbon: Used carbon may contain hazardous substances and must be disposed of in accordance with environmental regulations.

To overcome these issues, facilities often use humidity control systems, pre-filters, or hybrid technologies that combine activated carbon with other treatment methods.

Operation and Maintenance

Proper operation and maintenance are critical to ensure the long-term effectiveness of an Activated Carbon Odour Control system. Key practices include:

Regular monitoring: Use gas detectors or olfactometry to assess performance and identify breakthrough.

Scheduled media replacement: Replace carbon based on usage rates, odour loading, and manufacturer recommendations.

Airflow management: Ensure consistent and appropriate airflow through the carbon bed to maximize contact time.

Pre-treatment of air: Remove dust, grease, and excess moisture to prevent clogging and extend media life.

Inspection and cleaning: Periodically inspect the housing, seals, and ducting for leaks or blockages.

Cost Considerations

Activated carbon systems are relatively affordable in terms of initial investment and operational costs. The main expense is the periodic replacement of the carbon media, which varies depending on the odour load and system size.

While passive filters and cartridge systems are low-cost, larger systems may require capital investment in fans, housings, and monitoring devices. However, when compared to chemical scrubbers or advanced oxidation systems, activated carbon often provides a better balance between cost and effectiveness for small to medium-sized applications.

What is Activated Carbon?

Activated carbon, also known as activated charcoal By AQOZA , is a highly porous material created by heating carbon-rich substances such as coal, wood, or coconut shells in a controlled environment. This process, called activation, removes non-carbon elements and forms a network of tiny pores within the material, significantly increasing its surface area. The expansive surface area and porous structure make activated carbon highly effective at adsorbing various gases, liquids, and odorous substances, making it an ideal solution for air purification and odour control.

How Do Activated Carbon Odour Control Units Work?

Activated Carbon Odour Control Units operate through a process called adsorption, where molecules from gases or vapours adhere to the surface of the carbon. The air containing odorous substances is drawn into the unit via a fan or ventilation system. As the air flows through the activated carbon filter, odorous molecules attach to the carbon particles, trapping them and preventing them from circulating back into the air. This process efficiently removes a wide range of odours, including volatile organic compounds (VOCs), ammonia, sulfur compounds, and other harmful or unpleasant gases.

The effectiveness of these units depends on factors like the type of activated carbon used, the carbon’s surface area, and the airflow rate through the system. In some cases, the activated carbon filters may be impregnated with additional materials or chemicals to improve their ability to target specific odours, such as smoke, pet smells, or industrial emissions.

Conclusion

Sewage treatment plants are essential for maintaining the cleanliness and health of our environment, but they often come with an unpleasant odor. The stench typically results from the breakdown of organic matter, the release of hydrogen sulfide, and other microbial activities. If you're managing or living near a sewage treatment plant, the odor can be a constant challenge. Thankfully, there are effective ways to minimize and even eliminate these odors, and one of the leading solutions in this area is Aqoza.

What Causes the Smell in Sewage Treatment Plants?

Before exploring solutions, it's essential to understand the primary causes of bad odors in sewage treatment plants. The odors generally stem from:

Sulfur Compounds: When organic waste breaks down anaerobically (without oxygen), it produces hydrogen sulfide, a gas responsible for the characteristic “rotten egg” smell.

Methane: This colorless and odorless gas can escape into the air when waste decomposes, contributing to the overall unpleasant environment.

Ammonia: Another compound that forms during the decomposition process, ammonia has a sharp, pungent odor that is easily detectable.

While odor is unavoidable in some degree, various solutions can minimize it and maintain a more pleasant environment around the plant.

How to Remove Smell from Sewage Treatment Plants

There are several methods for reducing or eliminating smells in sewage treatment plants, including both biological and chemical treatments. Here’s a look at some of the most effective solutions:

1. Aeration Systems

Aeration systems, such as diffused or mechanical aerators, add oxygen to the wastewater. By increasing oxygen levels, the breakdown of organic material shifts from anaerobic to aerobic processes. This helps reduce the production of foul-smelling gases like hydrogen sulfide and methane. Aeration also improves the overall efficiency of the treatment process.

2. Biofilters and Bioaugmentation

One highly effective biological method for odor control is the use of biofilters. Biofilters consist of a medium (often made of organic material) through which air or gases are passed. The medium supports microbial growth that helps to break down and neutralize the odorous compounds. Aqoza, a leading brand in odor management, offers innovative bioaugmentation treatments that introduce specific bacteria designed to target and eliminate sulfur compounds, reducing the smell from the treatment plant.

3. Chemical Neutralizers

Chemical neutralizers are another option for treating sewage odors. These chemicals neutralize the smell-producing compounds, such as hydrogen sulfide and ammonia, converting them into non-odorous compounds. While effective, chemical treatments must be carefully managed to avoid creating harmful by-products or damaging the plant’s ecosystem.

4. Odor Scrubbers

Odor scrubbers use chemicals or biological processes to "scrub" the air and remove unwanted odors. These systems are designed to capture and neutralize gases before they escape into the atmosphere, preventing odors from affecting the surrounding area. Aqoza offers advanced odor scrubbing systems that help significantly reduce the release of harmful gases, creating a cleaner, more pleasant environment.

5. Regular Maintenance and Cleaning

Proper maintenance of sewage treatment plants can go a long way in minimizing odors. Regular cleaning of tanks, pipes, and other equipment helps prevent the buildup of waste and the subsequent release of gases.
