ON05 – Self-ventilation system for odor & infection control in aircraft toilets

For passenger aircrafts, the amount of flushing water was significantly reduced by the use of vacuum flushing. However, some flushing water is still needed, and the recirculated use of the water is necessary, which may lead to odor & infection concerns. It is also suspected that the during toilet flushing, even by vacuum flushing, some vapours may still escape into the lavatory. The idea of this project to examine the existing aircraft and other toilet design features for odor & infection control. One possible mechanism is to allocate part of the existing exhaust air through the toilet interior so that the toilet odour/infectious particles would not escape in the lavatory. Other possible development would be also given out.
