through a controlled and monitored flow, from the loading of the material to be processed to the expulsion of clean nontoxic and sterile air and inert solid residue. The system includes; a waste loading module (301, a shredding module (331, an injection module (341, a first combustion chamber (40), a second combustion chamber (50), a fust cooling module (60), an electrostatic module (701), a reducing catalyst module (70), an oxidizing catalyst module (80), a liquid filtering module (90), a neutralization module (100) and a second cooling module (101).

5305792 USED OR WASTE WATER COLLECTION SYSTEM FOR AN AIRCRAFT Ellgoth Huber; Frank Helge; Gmnwald Gerd; Mai Georg; Mau Karolin; Schliwa Ralf Deutsche Aerospace Airbus GmbH A used or waste water collection system for an aircraft has a waste water collection pipe that connects a kitchen sink with a collecting tank through a controllable valve. The waste water is transported by reduced pressure. For this purpose, the collecting pipe is connected to the suction system present in the aircraft, especially for removing sewage from the flushing of a toilet basin in the ‘aircraft.

5307697 CONTINUOUS, AUTOMATED, MULTI-STREAM SAMPLE COLLECTION AND ANALYSIS Davis H Forbes; Freed Anthony J Davis Water & Waste Industries Inc In the treatment of sewage, fresh, representative samples are continuously collected and analyzed at a number of different points in a sewage treatment reservoir. A submersible grinder pump is connected by a sample supply conduit to a continuous flow through filter, and ground sewage slurry is delivered at high velocity through the filter so that it scours the internal surfaces of the filter. The sewage slurry is continuously returned to the treatment reservoir, and filtrate continuously passes through a rotameter to a transparent sample collection reservoir. Discharge horn the sample reservoir is controlled by a solenoid operated valve, and a continuous overflow waste return conduit allows return of the filtrate to the treatment reservoir if the solenoid valve is closed. A computer controls operation of the solenoid valves and one or more analyzers for analyzing filtrate qualities (such as alkalinity). The solenoid controlled valves are connected to the analyzer through a manifold.

Hydraulic energy is recovered from the waste brine through a control device, having a central rotatable spool piece controlling fluid flow paths therethrough. The control device, in turn, directs the brine stream of reverse osmosis systems by diverting the brine into work exchangers used to pressurize the feed liquor. All components are made of corrosion resistant materials suitable for use in brine environments. Membrane pressure is held stable by equalization lines within the control device. System capacity can be adjusted externally

A waste disposer having a rotatable shredding element for grinding waste in a flushing liquid, an outlet for discharging ground waste material in liquid to a drain, an electrically-powered motor for driving the rotatable shredding element and a source for supplying flushing liquid me disposer that includes a detector for sensing the amount of electrical current flowing to the motor. The system includes, at least, one valve for controlling the flow of flushing liquid to the disposer which valve is controlled by means of a controller that is
