Owners of SOG® systems do not need to use any chemical toilet additives whatsoever because their active ventilation system guarantees the environmentally friendly decomposition of faecal matter by providing an increased supply of oxygen.
The fragrances used in chemical additives are only designed to cover up the odours of the biogas that escapes from the tank and into the vehicle interior when the gate valve is opened. The SOG® principle, on the other hand, bears parallels with the processes used in sewage treatment plants, which also avoid using chemicals and instead accelerate decomposition by feeding oxygen into their activated sludge tanks.
Owners of SOG® systems therefore don't need to waste any money on chemical additives.
