Abstract
A self-contained, oil flush medium toilet system is provided having a largely rectangular enclosure that separates the flush medium from collected waste and preprocesses the waste for subsequent removal. The device requires no connection to sewage or water lines, and can be installed with only electrical connections for continual operation. Waste is first received through a toilet bowl, whereafter it is consumed by the oil and falls under the surface thereof. The waste is then circulated below the oil, whereby it is continually aerated to promote aerobic digestion of the waste until it reaches a certain volume, where the processed waste exits the enclosure for further processing or storage. The oil flush medium is pumped through a particulate and carbon filter to maintain its condition, wherein the oil is immiscible with the waste to first consume it and remain above the waste within the enclosure during operation.
