Waste treatment system
First Claim
1. A waste treatment system for use with a vehicle, the vehicle having an engine with an exhaust manifold, the waste treatment system comprising:
- a holding tank for holding the waste;
a conduit line connected to an input source, selected from the group consisting of a head, a galley, a shower, and a bilge tank, and connected to the holding tank, for introducing waste into the holding tank from the input source;
an overflow line, connected to the input source, for discharging excess contents from the input source;
at least one macerator, fluid flow connected to the holding tank, for removing the waste from the holding tank and introducing the waste to the exhaust manifold;
an injector nozzle disposed within the exhaust manifold;
an injector pump, fluid flow disposed between the macerator and the injector nozzle, for pumping the waste from the at least one macerator to the injector nozzle;
a first sensor disposed within the holding tank;
a second sensor disposed within the bilge tank;
an overflow valve, fluid flow connected to the overflow line; and
a control module connected to the first sensor, the second sensor, and the overflow valve for monitoring the parameters of the first sensor and the second sensor and controlling the overflow valve based on the parameters.

Abstract
A waste treatment system for use on a vehicle having an exhaust manifold, the waste treatment system comprising a holding tank for receiving waste from a head, a galley, a shower or a bilge tank. At least one macerator is connected to the holding tank such that the macerator grinds the waste from the holding tank and recirculates it, as appropriate. A reducer is connected to the at least one macerator for reducing the size of the output of the at least one macerator. A centrifugal separator separates the relatively large waste particles coming from the reducer from the relatively small waste particles and liquid waste and recirculates the relatively large particles back to the holding tank. The remaining particles are sent to an injector pump that injects the waste, through an injector nozzle, into the exhaust manifold of the vessel. A control module controls the operation of the system based on various parameters, the parameters derived from various sensors.
