Abstract
A sanitation system, particularly for use in vehicles such as marine vessels (boats), trains, planes, etc. Into a holding tank with a sloping bottom containing sewage from a toilet system, such as a vacuum toilet system, about eight ounces of deodorant chemical is automatically injected into the tank approximately every 48 hours. This effectively controls odors while minimizing chemical consumption. A gas vent from the tank passes through a vent filter having a first type of activated charcoal effective against H.sub.2 S, and a minor amount of activated charcoal effective against amino acid gaseous compounds, the vent filter removing odors. A tank cap in the top of the cap supports "high" and "full" level indicator switches and allows for the injection of the chemical and the gas vent. A tank cleaning device comprising a piece of surgical tubing with a nozzle at its free end and connected to a source of liquid under pressure can also be utilized. In use, the nozzle impacts the tank walls while spraying liquid in it to effect cleaning. A control module and control panel provide for an indication of the tank liquid level, control of the injector pump, and control of the discharge pum…
