Specialist Services – Odour Removal

When it comes to odour removal, Juvenaire has extensive experience in providing solutions to handle most situations.

How is odour detected?

Odour is detected by the human nose called the sense of olfaction. The nose contains millions of olfactory receptor neurons situated in the nasal cavity which detects the presence and intensity of odour. The odour enters the nose and mouth and strikes the mucous membranes where the sensation of smell is transmitted to the brain by the olfactory nerve. The sensation of smell terminates in the olfactory lobe which is located in the brains lower frontal lobe. The olfactory lobe, in turn, interprets the sensation as a smell. From there, the interpreted sensation, in combination with experience, knowledge and suggestion, form a judgment as to whether the smell is good or bad.

Odour is interpreted by sensation, experience, knowledge and suggestion. There are two types of odours, “real odour” a pure sensation of smell transmitted to the olfactory lobe by the olfactory nerve and “psychological odour or heightened awareness”, odour that people think they smell based on experience, suggestion and past experience. This is the most difficult odour to address for the restoration technician.

How is odour transmitted?

An increase in humidity amplifies odour as does the increase in temperature and evaporation. The penetration of odours into soft furnishings is greatly increased by extreme temperatures.

Unfortunately there is no one solution that can be applied to all odours, therefore relying solely on one form of deodorisation technique for all odour control will most likely result in ineffective odour removal. Understanding what is causing the odour allows Juvenaire to put the steps in place to eradicate the odour.

Physical procedures for Odour Removal

  • Eliminate the source – The first universal step in odour control is to eliminate the source by removing the debris or the contaminants.

  • Clean the contaminated area – Walls, ceilings, hard floor surfaces, concrete, carpeting, upholstery fabrics, drapery and other surfaces may have absorbed the odours which require extensive cleaning for the final removal of the odour. These may not be in direct contact with the odour source however must be considered for complete odour removal.

  • Recreate the conditions of contamination – it may be necessary to increase the temperature to recreate the similar conditions allowing the pores of the materials to expand to allow proper penetration of spray, fog or ozone gas to allow the odours to be effectively removed.

  • Sealing the source – It may be necessary to seal the source that was exposed to the contaminants. Sealing the surfaces exposed to the concentration of malodours may be required for permanent odour removal and will prevent the evaporation of malodours into the atmosphere.

  • The right process – Understanding the type of odour can assist in the right application for its removal. Some odours such as protein odours or decomposing body odours are much more difficult to remove than the odours caused by tobacco smoke or a small kitchen fire.

Three effective methods for Odour Control

  • Masking – Disguising an odour with a more pleasant odour or covering an odour with a fragrance that is stronger. Almost all deodorising agents contain a masking agent. Masking agents are often used to provide temporary odour masking until permanent odour control techniques can be employed, however masking agents are the most effective means of counteracting psychological odour.

  • Pairing – A chemical which combines with the molecular structure of the malodour molecule or substance, which imports some of its own chemical properties. This transforms the odour cells chemistry into a new, hopefully, non odours compound. There are many water soluble deodorisers available plus electronic deodorising such as Ozone gas oxidizes.

  • Modification – A chemical which changes the molecular structure of the odour cell eliminating its ability to produce the odour. There are three (3) types: Attacking – counteracting; killing – bacterial based odours (disinfecting agents) and Enzymes – digesting.

No matter how strong or weak the odour, Juvenaire can remove it successfully and economically.
