How SOG® works
Mobile Toilets
The SOG® invention is a solution for eliminating toilet odours even without sanitary additives. How does it work?
A small, specially developed high-performance fan switches on automatically when the toilet valve is opened to create negative pressure in the waste-holding tank.
1. This immediately creates “suction” at the valve opening, causing fresh air to be drawn in. Odours arising during use are therefore drawn in with the air and directed outside. The inward flow of air also behaves like a seal and fully prevents any unpleasant biogases from rising out of the tank. This means more air (oxygen) is sucked into the cassette with each use. The flushing process also adds water each time.
2. The system switches off automatically when the toilet valve is closed, but continues to provide permanent aeration – as the oxygen supply – through a pipe or hose connection that is always open to the outside, thereby promoting the decomposition process.
SOG® uses biological decomposition
Like in composting, the microorganisms that break down the organic material need both oxygen and water, since they can only absorb nutrients in dissolved form. A good ratio of oxygen supply to water content is the key condition for the decomposition process.Water also consists of 88.81 percent oxygen by weight.
SOG® technology has been using these laws of nature successfully for more than 25 years, and even accelerates them by ensuring increased oxygen supply not only during use of the toilet but also when the valve is closed.
Another example where similar technology is used is the activated sludge tank in sewage treatment plants. By introducing compressed air, oxygen is pumped in to cover the oxygen needs of the microbes essential for the biodegradation processes (i.e. to promote decomposition).
Mercerator toilets
SOG®Compact and SOG®Compact Close for macerator toilets were optimised to meet customer requirements, with special value being placed on the reduction of unpleasant smells.
SOG®Compact and SOG®Compact Close integrated both electrical and other system components into a technical unit and thus offers the advantage of very simple installation with fixed tank toilets. Power is supplied by the vehicle's on-board 12 V power system. It is not necessary to make a hole in the tank or the vehicle.
Dry separation toilets
SOG®TT provides a remedy for the unpleasant odor when using dry separating toilets and is characterized by a specially optimized filter unit with an integrated fan.Thanks to its optimal konstruction, the fan can either be switched separately with a switch on the inside wall of the vehicle, or it can run continuously thanks to its low power consumption of 1.2 watts. In this way, it constantly absorbs all unpleasant odors from the dry-separating toilet, filtered and almost silently to the outside.The SOG® or SOG®II systems for mobile cassette toilets manufactured by us are not compatible with a dry separating toilet - not even in a modified form or by connecting individual parts. Any warranty claim will be void if it is used by third parties!
Using technology to make active use of oxygen
Our active SOG® -toilet ventilation requires no chemicals whatsoever. This makes it the perfect solution for both the environment and your wallet because you no longer need to use expensive sanitary additives.
