Working within the maintenance and industrial sector come with many regulations to prevent harmful pollutants being released in the air, and this includes controlling industrial odour. The smaller picture is that the unpleasant odour can drive complaints from local residents, but looking at it from a wider angle it can also seriously harm the earth’s health and release harmful toxins into the air.
Chemicals that are released from industrial processes can be controlled via synthetic methods which combine with the compounds to prevent them from being released into the atmosphere. Here is how it’s accomplished:
– Chemical additives: These systems are combined with the water that gets impacted by the odorous compounds. During the water phase, these compounds can be eliminated.
– Chemical sprays: These systems have a vessel which traps the odorous air and eliminates the compounds through effective chemical sprays before releasing clean air into the chamber.
This works similar to chemical sprays in using a vessel-based system to trap the odours and treat in a central location. These are beneficial but can be expensive as they need to be reactivated or replaced regularly.
Ozone – using ozone for odour control has been known to be effective, but it can be unstable and requires to be dealt with carefully. It is also only known to reduce the odorous compounds by around 80%
Ultraviolet – This is similar to ozone in that it only reduces the compounds in the air for around 80%. The use of radiation helps to create free radicals to oxidize the compounds that normally escape into the air.
Aeration – Industrial odour commonly comes from industrial waste water. This happens from odorous compounds being formed and being released in the air. An aerator can help to purify the compounds in the water, creating oxygen content.
Biological odour control methods make the most of microorganisms and bacteria to break them down or reduce their significance.
Biofilters – This is a rectangular pit where air is disbursed to the top. It filters through a layer of rock or gravel and then through another organic matter. It’s here where it feeds on the bacteria to prevent the air being polluted.
Bioscrubbers – As these systems rely on microorganisms, it maintains an odorous environment to make sure they can thrive and do their job. This is so collected air can be forced upward through the vessel and the water within the vessel can be recirculated around where the microorganisms can feed on the odorous compounds before releasing clean air at the top of the chamber.
Biotrickle Filters – These systems allow the microorganisms to grow within the vessel. Then the water passes through and rinses away the odorous compounds and allows the air to travel upwards from the vessel and release fresh air.
By controlling industrial odour and emissions that are released into the air, factories and manufacturers can keep within regulations without disturbing the environment.Click See our industrial odour extraction solutions here.
