Malodour Management by means of biological air cleaning

Another department of the company deals with the adsorption [1] bad odors. The substance can be applied with our technology, such as sewage treatment, the professional animal breeding or in smoking lounges, almost everywhere where bad smells.

In toilets, the active ingredient for biological smell adsorption [1] is often combined with essential oils.

Stench smell is been sensed as the opposite of fragrancy. Pleasant smells promote well-being, are appealing and may boost our performance. Stench solves the contrary, can cause nausea, disgust and repulsion.

Some of the known naturally occurring malodour substances are already in the almost inconceivable, low concentration of stink molecules, sometimes only a few molecules per million (ppm = parts per million). These substances can have physiologically negative effects up to toxic and can even lead to functional disorders of the central nervous systems in humans and animals.

Among the toxic substances known of this type include sulphide and ammonia, both poisons, with a maximum allowable job concentration of 10 ppm or 50 ppm. The human odor thresholds for these substances are however far below 1 part per million.

The statement "stench makes Sick!" bases precisely on this fact. And therefore, the elimination of stench is not only an aesthetic desire, but an absolute need for hazard prevention and health care.

There are several ways to eliminate odors and pollutants from the air: fighting stench with chemicals is only partially effective and can also cause further problems.


An effective method to eliminate odors quickly and without sustained health and environmental impact, is biological air purification. By adsorption of olfactory with the help of macromolecules, almost all bad smell pollutants can be disintegrated in a biological way. This method is based on the technology of biological air purification products SINOEEN ® and AIRODEEN ®



[1] Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a film of molecules or atoms (the adsorbate). It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. The term sorption encompasses both processes, while desorption is the reverse process.
