The processing and collection of commercial wastewater and sewage often work as a major reason of unpleasant odors. This water also contains organic particles and materials, phosphorous and nitrogenous compounds whose by-products cause unpleasant odors. This happens due to the fermentation process that automatically takes place in oxygen-deprived media. Emission of similar odor also comes from the composite areas and waste management facilities.
Major Elements Responsible for Odor are:
· Nitrogenous compounds
· VOC (Organic acids, Aldehydes, ketones and much more)
· Sulfurated compounds
Selection of the best equipment takes place on the basis of fluctuating concentration, type of odor and detection levels. Hence, chemical scrubbers prove to be a perfect answer for eliminating malodor from the area thereby, keeping the environment clean.
Treatment Procedures:
The odor control system offers removal of odor from the sewage wet waste and sewage treatment plants. In order to save the aquatic life from this harmful sewage, various treatment processes have come to existence. Each process is conducted in a way to filter the utmost benefit out of it.
For this purpose, three types of treatments are commonly used:
· Bio Scrubbers
· Chemical Scrubbers
· Carbon Scrubbers
Carbon Scrubbers:
This process is also known as absorption. The overall process works by the use of activated carbon. These substances have the capability to absorb the odorous compounds. Therefore, when used, it will certainly provide a desired result and prevent from harmful emission from industries. The whole process works by passing the untreated air through activated carbon. When it passes through the bed, it release clean air and make atmosphere safe for breathing.
Chemical Scrubbers:
This is the widely used technique throughout the world for treating waste water. Most of the industries make use of this scrubber since they have the capability to handle high pollutant concentration and higher flow. This is an appropriate solution for higher removal.
In this process, the odor is passed through a chamber where it comes into contact with the air stream combined with an aqueous solution. The liquid used in this process is water which is adjusted to proper oxidation and pH that helps in proper absorption of odorous compounds.
Bio-Scrubbers:
This is an eco-friendly solution for maintaining a proper environment. The overall process works by the use of micro-organisms. This eliminates the use of chemicals and hence renders a clean atmosphere. Bacteria along with other micro-organisms effectively absorb the pollutants. Using these materials for wastewater treatments proves to be extremely beneficial.
These are three most effective ways to get rid of pollutants. From the many, biofilters proves to be extremely efficient since they can provide a clean atmosphere without making use of harmful chemicals. Their benefits make them a preferable choice for industrial use.
