Odour Abatement

Odour emissions from industrial practices and waste water treatment plants are under continuous regulatory and public scrutiny. Enva has a range of odour abatement solutions, depending on the source and root cause of odour emission, to help companies remain compliant with their IE/IPPC, EA and SEPA site licence requirements.

Our experienced teams apply Best Available Techniques (BAT) in a collaborative approach with our customers, to deliver optimum solutions that balance capital and operating costs. 

We work with consulting engineers and utility companies to manage odour control at all stages of waste water treatment including sludge processing.

Enva is the U.K. and Irish agent for Neutralox, a specialist manufacturer of cutting-edge odour control equipment. Neutralox provides a treatment technology that utilises ultraviolet light. It does not require chemicals, has a small footprint, low operational and maintenance costs and is not sensitive to varying loads. 

Neutralox works by photoionisation. Strong oxidising agents are produced by UV light which oxidises odorous substances in the presence of a catalyst. 

Photoionisation systems work by applying high intensity ultraviolet (UV) light and using specialised catalysts to effectively remove certain odours from contaminated air. These systems have the added benefit of disinfecting the air, while also using no chemicals, less power, and taking up less space than other conventional treatment options. Read more

Activated carbon ensures removal of specific VOCs and other organic contamination. Enva is the Irish agent for industry specialists Jacobi Carbons.

Activated carbon is renowned for its ability to control gaseous odours by ensuring the removal of specific VOCs and other organic contamination. The carbon acts as a sponge, soaking up odours as the air passes over it. Activated carbon becomes saturated quickly, meaning it needs to be replaced or regenerated regularly. 

The most prevalent uses of activated carbon in today‚Äôs world revolve around the treatment of process water, industrial and commercial wastewater and air/odour abatement issues. When converted to activated carbons, carbonaceous source materials possess the ability to effectively purify and remove a vast array of contaminants from water and wastewater streams. Read more

Enva can provide systems that are installed at the ground works stage of construction or as boundary spray barrier systems at sensitive sites.

Misting and dosing systems use specialised blends of essential oils, surfactants and organic compounds to encourage the absorption and decomposition of odours, converting molecules into non-volatile compounds. They are typically installed at the ground works stage of construction projects or as a boundary barrier at sensitive sites,and can eliminate both airborne and surface-based odours.

Enva supplies a range of chemicals for the purpose of offensive odour abatement, e.g., hydrogen sulphide, mercaptans and ammonia. Our expert team assesses the odour source to identify the most appropriate solution and subsequent effective application.

There are a range of chemicals that can be used to prevent odour generation or to mask existing offensive odours e.g. to prevent hydrogen sulphide formation or to mask malodours produced from activities such as waste recycling, composting and landfilling. Speak to your our team of experts to determine the most appropriate solution and application of odour control chemicals for your requirements. Read more

Enva represents Tholander, a market leader in the design, installation, commission and aftercare of active air scrubber systems. Scrubber system types include chemical, water, biotrickling and activated carbon. 

Air scrubbing systems are a very successful method of removing both particulates and gases from industrial exhaust streams in a single system. They work by passing contaminated air through a scrubbing liquid, typically water, though it could also be a chemical solution such as caustic or acid. Particulates or gases are collected in the scrubbing liquid, which is then treated and disposed of safely. Air scrubbing systems are most commonly found at industrial sites like petroleum refineries, chemical processing facilities, acid manufacturing plants, and steelworks.

Fat, oil and grease (FOG) is a by-product of cooking foods such as vegetable oils, meats and dairy products. Food Service Establishments such as restaurants, takeaways and pubs are a prime source of FOG, which can pass into the sewer system during cleaning processes. When hot, liquid FOG can easily enter sinks and drains, however when FOG cools, it solidifies, blocking and damaging sewer pipes and causing problems during the waste water treatment process.

In addition to unpleasant odours, FOG-related blockages can result in sewer overflows due to reduced capacity or burst drain and sewer pipes. This can have significant environmental consequences including land contamination and risk to public health.
