The functional principle of SOG®

1. This creates a "suction" at the slider opening, which sucks in fresh air and also the odors that occur during use and directs them outside. The drawing in of air acts like a seal and 100% prevents all unpleasant fermentation gases from rising from the tank. With each use, more air (oxygen) is sucked into the cassette. Water is also supplied through the flush every time.

2. After automatic switch-off (closing of the slide), there is permanent ventilation - i.e. oxygen supply - through a pipe or hose connection that is always open to the outside, which thus promotes the decomposition process.

The principle of decomposition via oxygen is state of the art.

In addition to ending odor nuisance, active toilet ventilation has the great advantage that it does not require the constant use of toilet additives. In chemistry, a distinction is made between chemical and biological decomposition (decomposition - breakdown of a chemical compound).

As with composting, the microorganisms need oxygen to break down organic material and, since they can only absorb their food in dissolved form, also water. A good ratio of oxygen supply and water content is the decisive condition for the decomposition process.

The SOG^® technology uses these laws of nature - with success for more than 25 years - and accelerates them, since an increased supply of oxygen is guaranteed both when the toilet is used and when the slide is closed.

Another example where this technique is used in a similar way is the activated sludge tank in the sewage treatment plant. Oxygen is pumped in by supplying compressed air in order to cover the oxygen requirements of the microorganisms necessary for the biological decomposition processes (i.e. to promote decomposition).
