The DESOZONE system can deodorize 250 to 20,000 m3/h of
air from industrial facilities and municipal sewage plants. The
system is a complete packaged unit that includes: the blower,
washing system with packing, recycling pump of wash water
solution (if necessary with chemicals), ozone mixing devices,
ozone generator and control panel.

A serious problem for sewage plant operations is the generation of foul smelling odors, especially when they are located
within a residential area. Studies have shown that air pollution from odors is the greatest problem that these installations
must deal with and for which they receive the most complaints from the local population.
The substances responsible for the odors in the vicinity of treatment plants are generally gaseous inorganic products or highly volatile organic compounds. The inorganic substances are mainly the result of biological activity in the sewage treatment process, the latter are often caused by the presence of industrial wastes in the sewer. Compounds such as mercaptans, skatoles, aldehydes, ketones and inorganic acids are recognized as being among the causes of bad- smelling odors at the outlet of sewer lines and in treatment plants. In general these compounds contain nitrogen or sulphur atoms. Ammonia and hydrogen sulfide are considered to be the main causes of foul odors. Hydrogen sulphide is considered to be the main cause when the sewage comes mainly from households. Its presence is related to the onset of putrefaction in reducing environments characterized by low values of the oxidation-reduction potential.
Defining an air washing system requires a precise definition of the quality and quantity of the air to be treated and the size of the particles involved. Significant factors in designing odor elimination system are:
