Odor is considered one type of air pollution that does not directly affect human health but can cause stress and reduce their quality of life. The foul odors originate from various industrial sources like fish, meat, food processing plant, sewage, domestic refuse processing plants, paint, paper pulp, chemical treatment plants, oil refineries, mist collectors, livestock processing facilities, leather tanneries, plastic manufacturer industries, solid and liquid waste management, and several other plants that need anaerobic decomposition.
Hydrogen sulfide (H2S) is the natural anaerobic digestion of organic compounds that produces a strong and vomitous smell.
So the common odors around the treatment plants smell like ammonia, garlic, and rotten eggs, sometimes described as organic or earthy. Control of the odor is one of the most challenging tasks for the industry. That’s where Odor Control Systems come in handy.
Odor Control Systems
Odor Control Systems are equipped to completely reduce or eliminate unwanted scents from all the sources within an air supply. They mask the nauseating smell with a strong and pleasant fragrance. On the other hand, they have the quality to reduce the rodents, and insects that attract by untreated scents. Further. Odor Control Systems are packed with three common technologies. The categories include Biological Oxidation or Biotrickling filters, Chemical Scrubbing (Chemical or Carbon Adsorption), and Combination Technologies.
Biological oxidation System: Biofilters are used in biological oxidant systems. Installed inside pipes or tubes, they eliminate sewer gas odor. In the process, bacteria and other microorganisms are dissolved by using organic carbon into cellular material and carbon dioxide. It is widely used in the wastewater treatment plants, chemical, and pesticide industries, and high-speed machining with coolant industries.
Chemical Scrubbing System: Also called chemical absorption, Chemical Scrubbing System works by shifting one substance directly to another substance. Absorption could be a chemical or physical process.
Combination Technologies: These technologies are the combination of technologies of all the odor control technologies mentioned above. They work by masking odors while serious odor control systems neutralize them.
It is worth noting that proper control is not possible without installing proper odor control. In absence of the odor control systems, industrial odors can drift into nearby areas and cause serious problems to people and animals. That’s why every manufacturing plant and factory must look for solutions to control the odor that emits from their plants.
