Following AIR SPECTRUM ENVIRONMENTAL LTD’s recent analysis of the performance of odour suppression chemicals, the industry experts have rationalised their market-leading range to ensure clients are receiving the optimum product to meet their requirements.

This has led to Midlands-based Air Spectrum rationalising their Odr range from seven blends to four – while at the same time still offering the highest quality of odour neutralisation.

The move is particularly relevant given the on-going drought conditions that are gripping much of the country as businesses that rely on being able to successfully neutralise the odours they produce can now do so in the most water-efficient way possible. On the 16th April with water levels at their lowest point since 1976, official drought conditions were declared in another 17 counties.

Following two dry winters which the UK’s Environment Agency says “left rivers and ground waters depleted”, the areas affected now include much of the Midlands and the South West. Counties affected in the Midlands include, Nottinghamshire, Leicestershire, Derbyshire, Staffordshire, West Midlands, Warwickshire, Shropshire, Worcestershire, Herefordshire and Gloucestershire. And in the South West, Cornwall, Devon, Dorset, Somerset, Bristol, South Gloucester, Hampshire and Wiltshire are all affected.

Air Spectrum’s re-engineered four-strong Odr range still has the capability to neutralise a vast variety of odours, while they also ensure the best chemical compositions to meet their customers’ requirements.

Mark Thomas, general manager of the Worcester-based company, commented: “Air Spectrum’s Odr range of odour neutralisers is specifically designed to negate the threat of these issues, by controlling odour in any environment. Its primary function is to neutralise odour before it leaves the site boundary or processing outlet.

“Operators using Odr protect their neighbours from exposure to annoying smells, eliminating the possibility of complaint or investigation and ensuring compliance with air pollution regulations.

“Odr is a best-selling range of organic, non-toxic, foodgrade odour neutralisers using bio-degradable essential oils collected from sustainable resources. Some Odr types are fragranced but, unlike masking chemicals that can cause greater environmental problems than they resolve, Odr neutralises malodour by removing it from the air.”

Odr combats odour in five different ways – pairing, oxidisation, adsorption, absorption and combination. These work as follows:

1.   Pairing Odr contains substances which will chemically pair with odorous compounds, changing the properties of the odour molecule, rendering it odourless.

2.   Oxidation Odour molecules can be oxidised to produce an odourless solution. A combination of oxygen, Odr and hydrogen ions generates a safe reaction, resulting in odour neutralisation.

3.   Adsorption Certain odorous molecules will attach themselves to Odr neutraliser, generating a minute energy charge that partly neutralises their odour and adsorbs them into a larger odourless compound.

4.   Absorption Certain odour compounds dissolve into Odr neutraliser, losing their odour in the process.

5.   Combination Odr odour neutraliser combines with certain odorous molecules, changing their structure to generate new molecules that are environmentally friendly and completely odourless.

Air Spectrum’s four different blends target a wide-ranging variety of odours, with Odr1 being a neutraliser for use where light or intermittent odour is a problem in workplaces, such as composting facilities or landfill sites. Odr2 is aimed at heavier odour problems, such as waste-transfer stations.

If there is a constant stream of odour causing discomfort to employees and neighbours, Air Spectrum recommend Odr3, whereas Odr4 can be used to combat high levels of odour on an intermittent or constant basis, such as in food processing and manufacturing facilities.

The new line-up of Odr is available now and will be accompanied by an all-new technical brochure from May 1, which can be obtained by emailing hayley.jordan@specenv.com.
