Abstract:
Water, preferably fresh potable water, is electrochemically, e.g. electrolytically, treated to achieve disinfectant properties. The electrochemically treated water is sprayed onto the toilet seat and directed into the toilet bowl for each flush cycle of an aircraft toilet system, so as to clean and disinfect the toilet seat and the toilet bowl. The electrochemically treated water has a direct germ-killing effect on the seat and bowl, and also disinfects the arising wastewater that is conveyed to and stored in a storage tank. For flushing the toilet bowl, the electrochemically treated water may further be mixed with reused graywater, which is thereby disinfected.
Abstract:
A system is provided for processing a volume of human sludge with sea water and chemical reactants to generate methane gas and to reduce the volume by at least eighty percent (80%). This is by having a series of processing containers for receiving, holding and processing the sludge volume by way of a volume of sea water and chemical reactants. A first processing container is constructed with a means for mechanically agitating the sludge volume and collecting methane gas released therefrom. The system further has a second processing container for processing a sludge mixture transferred from the first processing container for further treatment of said sludge mixture by sea water and chemical reactants with a means for collecting methane gas released therefrom. A filter system for filtering said sludge volume and said sludge mixture is included in each of the processing containers.
Abstract:
An apparatus is disclosed for the treatment of sewage on board ships comprising a detritus chamber, a metering and comminuting pump, a chemical container, a preliminary sedimentation tank, an electroreactor vessel and a final sedimentation tank and sludge container attached in configuration and in parallel in the form of a compact unit in a common supporting frame.
Abstract:
Apparatus designed to be interposed between the discharge of a marine toilet and the overboard discharge line of a vessel comprising a treating chamber provided with inlet and discharge openings through which the effluent is delivered to the chamber for treatment and pumped therefrom following treatment, an impeller supported in the chamber for rotation therein which, in conjunction with the hemi-toroidal formation of the chamber, produces vortexlike movement of the effluent which reduces the particle size by hydraulic attrition and mixes it with chemicals deposited therein, a dispenser for depositing the chemicals in the chamber, a pump for introducing flush water to the chamber, a pump for discharging the treated effluent and the flush water and controls for timing the cycle of operation from the time it is initiated by flushing the toilet until it is timed out by a timer in the control circuit, together with suitable indicators for indicating the condition of the apparatus at any given time, and to prevent operation in the event that the chemicals are depleted.
Abstract:
The toilet system includes an evaporator tank having an inlet and an outlet that is at the top portion of the tank, a first electrical heater mounted on the tank, macerator/transfer pump means connected to the inlet of the tank to transfer flushed waste from a toilet to that tank, a vapor treatment system including a vessel having an inlet and a vent outlet and containing a bed of catalyst, first conduit means connected to the outlet of the tank and to the inlet of the vessel to transfer vapor from the tank to the vessel, a second electrical heater mounted on the conduit means to heat vapor passing from the tank to the vessel of the vapor treatment system, and second conduit means connected to the first conduit means between the mounting of the second heater and the evaporator tank to introduce pressure air into the vapor from the tank before the heating of the vapor. The toilet system further includes means mounted in one of said first and second conduit means and responsive to a condition indicative of inadequate pressure of air in said second conduit means to prevent continued operation of the second heater. The toilet system has low-level sensing means mounted in the evaporator tank that is operative, when the level of liquid waste in that tank is below a predetermined low level, to prevent the operation of the first heater. Also mounted in the evaporator tank is high-level sensing means that is operative, when the level of liquid waste in the tank has raised to a predetermined higher level to prevent the operation of the macerator/transfer pump means until the level of liquid in the tank is lowered by evaporation of water from the liquid waste in the tank or the discharge of liquid waste from the tank.
Abstract:
A waste treatment system especially designed for use on a marine vessel or land based vehicle which includes a housing enclosing a bowl having a valve which closes an opening in the bottom thereof. Upon actuation of the valve to an open position, solid and liquid waste materials are discharged onto an endless coil spring belt, the arrangement being such that the liquid falls through the spring openings into a sump while the solid waste products are discharged from an end of the rotating belt into an incinerator for eventual destruction by burning. To provide a flushing liquid for the bowl, liquid from the sump is pumped through a filter which removes any solid particulate matter in the liquid and is discharged therefrom to a chlorinator which kills bacteria in the liquid prior to discharging it into the bowl. The discharge end of the pump also is connected to a hydraulic device which actuates the valve to discharge waste products from the bowl in accordance with the demands of a timer which is used for controlling pumpmotor operation. A timer also is set to control operation of the incinerator for burning the solid waste products once during each 24 hours period.
Abstract:
A sewage disposal comprising a fossil-fuel fired steam generating unit having a furnace chamber and burner means for maintaining a high temperature zone in the furnace chamber, nozzle means for injecting a liquid-solids sewage mixture into the combustion zone, the sewage input being regulated to maintain a sewage to fuel input ratio resulting in substantially complete vaporization and incineration of the liquid-solids sewage mixture within the furnace chamber.
Abstract:
A marine sewage treatment system having a digestor unit including a first tank receiving the sewage effluent, a secondary treatment unit including a second tank receiving the fluid discharged from the first tank and a final filter receiving the fluid discharged from the second tank, the first and the second tanks including baffles controlling the flow of fluid within the tanks and the first and the second tanks each being supported via a guide and anchor assembly for automatically leveling and agitating the fluid within the first and the second tanks.
Abstract:
A filter-adsorption media, such as activated carbon, is supplied to one end of a screw conveyor having a variable pitch along its length with the greater pitch being at the supply end. Sewage, such as from a marine toilet, is passed through a macerator and chemically treated before being introduced into the central portion of the screw conveyor to be mixed with the filteradsorption media and compacted as the screw conveyor is rotated. The compacting produces a mixture of filter-adsorption media and sludge at the discharge end while the liquid is passed through the conveyor in counter-flow relationship, to the incoming filter-adsorption media and through the filter-adsorption media, and then to a discharge.
Abstract:
Process for the substantial reduction of bacterial count in sewage waste and assembly for treating same. The assembly comprises means for conveying sewage waste material to a treatment zone, means for retaining the waste material therein, temperature control means to insure that the contents retained in the treatment zone attain a temperature at least that of boiling water and means for passing the treated sewage waste from the treatment zone so that upon discharge of the treated waste material, substantially all of the bacteria have been destroyed.
