Parsons - Odour Control Systems
Odour is a tenuous and subjective issue. Chemical fume scrubbing is relatively straight forward, it is usually a limited number of known chemicals to be dealt with and our Chemical Engineer can quickly come up with a relevant stoichiometric equation.
Odour is different. There are so many compounds that ‘smell’ that the only object capable of detecting them all is the human nose, and every one of those is different. It is from this basis that the Odour Unit, the most commonly used measure of smell, is calculated. The Odour Unit is genuinely calculated by a team of people sniffing smelly air out of plastic bags. Well its a bit more complicated than that but…..
Whilst the Odour Unit does give a number, this is based of perception not actual quantities of known compounds making chemical analysis virtually impossible.
This is where Parsons’ thirty plus years proven experience in the odour control industry becomes invaluable.
You can tie your self up in figures and percentage removal rates but we aim for one thing, ‘no offensive odour beyond the boundary’ and hold greatest sway by the most usual comment from our clients “The complaints have stopped!” Both of which are soothing to the EA Officer.
Parsons regularly supply odour control plant to the commonly odorous industries, sewerage treatment, abattoirs etc. but have occasionally run into the more specialised, from pressure cooked black bin bags to fried chicken and sausage skins. The outcome has always been the same.
