TODAY’S PATENT – WATERLESS FLUSH TOILET SYSTEM

The WATERLESS FLUSH TOILET SYSTEM was invented by George C. Roberts (Los Angeles, CA) on the 2nd of February 1982, bearing patent number US4313233A.

This invention pertains to the field of waste disposal and, more particularly, to the field of closed cycle waterless flush toilet system.

A waterless flush toilet system comprising a toilet and a gravity fed waste holding tank. The system utilizes a recirculating nonaqueous flushing fluid which is stored within the holding tank. The fluid, which is lighter than the waste material and insoluble therein, forms a stratified layer on the surface of the material. When the toilet is flushed, an air-powered pump draws a fraction of the fluid into the fluid inlet of the float, through the flexible hose and finally to the toilet. The fluid serves as a medium for transporting the waste material from the toilet to the holding tank. When the fluid is flushed into the tank, it separates from the waste material and returns to the stratified layer for reuse. An exhaust system utilizes a double-walled toilet to prevent exhausting of fluid or waste matter.
