Odour complaints may be caused by a variety of odorous compounds that are released or
generated by various wastewater processes especially Sewage Treatment Facilities. In a sewage Treatment Plant the Sewage Collection sump would be the main source of Odour causing gases as there is a tendency of the sewage going septic here. The major types of odors generated in Sewage Treatment Plants are:
1. Amines (fishy odor quality)
2. Ammonia, NH3 (ammoniac odor quality)
3. Diamines (decayed flesh odor quality)
4. Hydrogen Sulfide, H2S (rotten eggs odor quality)
5. Mercaptans (skunk odor quality)
6. Organic Sulfides (rotten cabbage odor quality)
7. Skatole (fecal odor quality)
However, the most common odour causing nuisance gas from the sewage treatment plant would be Hydrogen Sulphide (H2S) and Ammonia (NH3).
If these odour causing gases can be effectively removed by means of an odour control equipment then the residents living nearby or personnel working close to these installations can be spared from the inconveniences of having to live with the ‘smelly’ problem which could over the period of time lead to health problems.
The most effective method of removing Hydrogen sulfide and Ammonia is by means of Adsorption method and by using Impregnated Activated Charcoal as the Adsorbing Media.
In terms of odor control, adsorption typically refers to the use of activated charcoal to adsorb malodorous compounds into the activated carbon material. This is usually accomplished by passing the malodorous air across a bed of activated charcoal, allowing the adsorptive process to occur, and releasing the now clean air into the atmosphere. After the carbon bed has reached saturation, the bed adsorption capacity is replenished by washing it with chemicals.
Healthy environment is crucial to stress free healthy living.
Our odour control system consists of a Dry Gas Scrubber followed by a suitable Air Handling Unit (AHU) and ducting system to exhaust the malodorous stale air.
