What is surface odour control?

Odour issues often arise when organic waste or wastewater begins to break down, releasing unpleasant compounds into the air. Surface odour control offers a practical and low-cost solution for managing these emissions at their source, eliminating the need for large-scale infrastructure.

This approach is beneficial for facilities that generate odours from exposed surfaces, such as landfills, composting areas, recycling plants, and wastewater treatment sites.

Understanding how surface odour control works can help you determine when and where this method offers the most effective results.

What is surface odour control?

Surface odour control refers to the application of foaming odour neutralisers directly onto problem surfaces. The foam penetrates the material and neutralises odorous compounds, stopping them before they can escape into the air.

It's a simple yet effective method for maintaining air quality and meeting environmental standards in industrial and waste management settings.

How surface odour control works

Surface odour control systems operate by applying a foaming odour neutraliser directly to odour-producing surfaces. The foam works quickly to block and neutralise odours at their source while also helping to rebalance the surface microbiology.

Here's how this odour control process works:

1. Foam application: A foaming odour neutraliser concentrate, such as Cleanawater's Bektra 830F, is sprayed evenly over the affected surface.
2. Surface penetration: The foam expands and adheres to the surface, allowing the neutralising agents to reach odour-producing organic matter.
3. Odour neutralisation: The micronutrients and active compounds within the foam react with odorous compounds, neutralising them on contact.
4. Microbial control: The treatment encourages beneficial microbial activity that helps prevent future odour release.

Surface odour control is easily applied using a standard spray device and can be managed by a single operator.

What the foaming odour neutralising concentrate is made from

Cleanawater's Bektra 830F Foaming Odour Neutraliser Concentrate is formulated with a blend of micronutrients and natural compounds that safely neutralise odours. This unique formulation works by promoting natural biological processes that break down organic waste without generating harmful by-products.

Key ingredients include:

• Essential oils: provide natural odour neutralisation and a mild, clean scent.
• Purines and pyrimidines: support microbial activity for effective organic breakdown.
• Minerals and amino acids: strengthen the biological processes that control odour formation.
• Vitamins and complex organic extracts: enhance the foam's stability and effectiveness.

Bektra 830F is non-toxic, biodegradable, and free from bacteria, enzymes, and hazardous chemicals, making it a safe and sustainable choice for industrial and environmental odour management.

Where is surface odour control used?

Surface odour control is a flexible and practical option for facilities that generate odours from exposed surfaces or waste materials. Because it requires no fixed infrastructure, surface odour treatment can be applied quickly and effectively using a spray device operated by one person.

Common areas of application are:

• Landfills and rubbish dumps: Controls odours from decomposing organic waste and exposed tip faces.
• Composting operations: Neutralises organic odours released during microbial decomposition.
• Wastewater treatment centres: Treats odorous surfaces around aeration tanks, ponds, and sludge drying beds.
• Recycling plants and transfer stations: Reduces odours from tipping floors, loading bays, and vehicle areas.
• Hard surfaces and contained spaces: Suitable for driveways, pits, septic tanks, long drop toilets, and leachate ponds.

By controlling odours at their source, surface treatments help facilities reduce community complaints and maintain compliance with environmental regulations as outlined in the EPA Victoria odour control guidelines.

Comparison: surface vs misting systems

While both surface treatments and misting systems are effective methods of odour management, they differ in cost, setup, and flexibility. The table below outlines the key differences to help determine which approach best suits your facility.

Surface odour control is often preferred for short-term or mobile operations, while misting systems are suitable for larger facilities that need ongoing odour control.

Key benefits of surface odour control

Surface odour control offers a cost-effective and environmentally responsible solution for reducing odours at their source. Unlike masking agents or traditional air fresheners, surface treatments neutralise odours directly through chemical and biological action.

• Cost-effective treatment: Provides reliable odour control without the expense of installing fixed systems.
• Non-toxic and biodegradable: Safe for the environment, employees, and nearby communities.
• Fast-acting results: The foam neutralises odours immediately upon contact with the surface.
• Low maintenance: Requires minimal equipment and can be applied by a single operator.
• Versatile applications: Suitable for a wide range of industries and surface types.
• Supports environmental management: Helps facilities comply with workplace health and environmental standards.

These benefits make surface odour control an ideal choice for facilities seeking long-lasting, sustainable odour reduction without complex infrastructure.

Performance and environmental impact

Surface treatments do more than neutralise foul odours. They also improve environmental outcomes by addressing the root causes of odour generation. These treatments help reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD₅) levels, supporting cleaner water and air within industrial environments.

• VOC reduction: Decreases the release of volatile organic compounds that contribute to poor air quality.
• Reduced sludge formation: Minimises solid waste buildup in ponds, lagoons, and wastewater systems.
• Improved biological stability: Encourages natural microbial processes that break down organic matter safely.
• No harmful by-products: Eliminates odours without producing secondary pollutants or chemical residues.

By combining effective odour control with measurable environmental benefits, surface treatments align with best-practice air quality standards in the NSW EPA odour control guidelines.

Real-world examples of surface treatments

Cleanawater's surface treatment solutions have been successfully applied across major infrastructure and environmental projects throughout Australia. These case studies demonstrate the effectiveness of foaming odour neutralisers in reducing unpleasant smells, improving compliance, and protecting community amenity.

Blaxland Waste Management Facility

A VapourGard perimeter system was installed to address odour complaints from surrounding residents. Once operational, the system provided immediate results and significantly reduced community concerns. As the Blaxland Waste Management Facility expanded, additional units were added to ensure full site coverage.

Lucas Heights Resource Recovery Park

One of Sydney's largest waste facilities, Lucas Heights Resource Recovery Park, required a large-scale odour control solution. VapourGard was selected for its ability to deliver broad coverage around the site perimeter, helping the operation manage odours effectively and maintain compliance with environmental standards.

These examples demonstrate how Cleanawater's surface odour control methods deliver practical and sustainable solutions for diverse industrial and construction environments. Learn more through our case studies.
