Odor removal

Elimination of odors

Neutralisation of odors in the exhaust air of industrial plants and in wastewater treatment

The formation and emission of odors occur in many different production processes, both in industry, in commercial enterprises, and wastewater treatment plants. Due to the amendment of the Sewage Sludge Ordinance (AbfKlärV), the topic of odor elimination has recently also been discussed in the clarification of sludge drying and the operation of sewage sludge emissions-control plants have become enormously important.

Odors are produced, for example, in food production, roasting processes, the production of flavors and spices, and slaughterhouses. But also on sewage treatment plants, in sewer systems, in sewage sludge recycling plants, and in many other technical processes that produce exhaust air streams with sometimes complex mixtures of odorous substances.

The substances released in the process range from organic compounds such as alcohols, aldehydes, and ketones to sulfur-containing hydrocarbons such as mercaptans and cadaverine to inorganic substances such as ammonia (NH3) and hydrogen sulfide (H2S). The use of solvents such as acetone and other VOCs can also cause significant odor emissions.

For the treatment of these and other odor emissions, uviblox GmbH offers reliable and effective methods for the removal of odors and VOCs from exhaust air streams. uviblox GmbH offers suitable odor elimination systems depending on the volume flow of the exhaust air and the type of pollutants and pollutant load:

  • UV photo-oxidation systems
  • Activated carbon filter
  • Chemical scrubbers
  • Catalytic oxidation plants

Removing odorous substances from exhaust air

The following are examples of frequently occurring odor pollutions that can be treated using the uviblox® FOX technology's exhaust air purification:

  • Hydrogen sulfide, mercaptans, sulfides, and other organosulfur compounds
  • Ammonia, amines, skatole, cadaverine, and other nitrogenous hydrocarbons
  • Butyric acid, acetic acid, and carboxylic acids in general
  • Aldehydes and ketones,
  • Alcohols, ethers, esters, phenols, and other oxygen-containing hydrocarbons
  • Terpenes, terpenoids, and other fragrances
  • Roasted aromas and fumigants
  • Spice aromas and other substances from the food industry

The emission of odors and pollutants is a burden on the environment as well as a nuisance to the neighborhood around the production facilities. In order to avoid uncontrolled emission of odors, according to the technical instructions for keeping the air clean, the air requirements for emissions are:
"As a rule, odorous exhaust gases are to be supplied to exhaust gas purification devices or equivalent measures are to be taken." (TA-Luft, paragraph 5.2.8)
The odor load must not exceed 500 GE/m3 in many processes, such as the treatment of waste or the drying of sewage sludge.
