Jet pump macerator pump sewage handling system

A toilet system for a mobile unit comprising at least one toilet bowl mounted on the unit, a bowl discharge pipe connected to said bowl, an evacuation valve mounted in said bowl discharge pipe, a transfer manifold pipe to which said bowl discharge pipe is connected, a non-clogging jet pump connected to said transfer manifold, a tank connected to said non-clogging jet pump, a macerator pump with an input port connected to said tank and an output port connected to said non-clogging jet pump, an air induction valve mounted in said manifold pipe, and a toilet flush valve;

• wherein said non-clogging jet pump comprises a first inlet passage, a second inlet passage and an outlet passage connected to said first and second inlet passages and a reduced cross-sectional portion between said first inlet passage and said outlet passage to form a venturi so as to apply suction to said second inlet passage when fluid flows between said first inlet passage and said outlet passage, wherein said inlet port of said macerator pump is connected to a lower portion of said tank, wherein said outlet passage of said non-clogging jet pump is connected to an upper portion of said tank;
• means for controlling said toilet system including a flush control to energize a flushing of the toilet system, a means for controlling said toilet flush valve, a means for controlling said evacuation valve, a pressure sensor mounted on the output port side of the macerator pump for sensing the discharge pressure of the macerator pump, and means for controlling said air induction valve after flushing has occurred to allow high speed air to be drawn through said transfer manifold pipe.
