US Patent 8082605 Low flow hygienic apparatus and methods

A low volume hygienic apparatus used a high pressure spray to break up solid waste material in a containment chamber and to push liquid and broken-up solid waste from the containment chamber. A high pressure nozzle is pointed into the containment chamber and configured to break-up the solids using a prescribed pressure level and to propel the liquids and the broken-up solids from a chamber interior through a chamber outlet of the containment chamber. A completing structure is disposed between the chamber outlet and a drain and is configured to draw liquids and broken-up solids from the chamber at the end of a flushing cycle.
