Abstract:
A system for treating human waste in remote or portable toilet facilities, including a holding tank that stores waste; a heat reservoir that receives waste from the holding tank, heats the waste to kill fecal coliform bacteria therein present, and routes the heated bacteria-free waste back through the holding tank. The holding tank maintains the heated bacteria-free waste separate from the contaminated waste but passes residual heat from the bacteria-free waste to the untreated waste. In one embodiment, a centrifuge receives the bacteria-free waste from the holding tank, separates the liquid waste from the solid waste, and discharges the liquid waste from the system. In one embodiment, the waste is pumped through the system to be heated in incremental portions.
Abstract:
A method for water recovery from the atmosphere of a habitable pressurized module laden with water vapors released by the inhabitants of said pressurized module, comprising the steps of condensing vapor to produce a gas-liquid mixture, filtering said mixture, carrying out catalytic oxidation of undissociating organic compounds contained in the gas-liquid mixture into dissociating ones by means of a metal-carbon catalyst containing at least one metal of the platinum group, separating condensate from said mixture, sorption-purification of condensate by passing it through activated carbon and ionites followed by disinfection, mineralization and preservation of purified condensate. The system for realization of said method comprises a successively arranged means for condensation of water vapors, a filter, a catalytic oxidation reaction vessel, a condensate separation unit, a sorption purification unit and a water conditioning unit.
Abstract:
A method and apparatus for treatment of waste on ships and the like, in the form of solid waste and black water collected in a tank from reduced flush toilets. The solid waste is mixed with black water from the tank in a drum. Rotating knives in the drum effect the disintegration of the solid waste, and also the picking up of the waste in the drum from the bottom thereof to permit it to drop repeatedly by gravity from the upper regions of the drum. A flow of hot air is passed through the drum and hence through the dropping mixed black water and disintegrated solid waste. The axis of the drum is substantially horizontal, and may be slightly inclined with bottom ridges to inhibit the flow of liquids therealong.
Abstract:
A system and apparatus for disinfecting sewage water and removing suspended solids therefrom by in-situ treatment with chemical agents and gases, each produced electrolytically, comprising a treatment chamber, disinfecting and solids conveying means including at least one pair of electrodes disposed in the chamber, solids removal means associated with the chamber, a source of aqueous alkali metal halide solution and optionally an ultraviolet light ray source and solids collection means.
Abstract:
A system for purifying and disinfecting waste water including container housing a disintegrating pump, a mixing vessel downstream from said container, and a closed vessel downstream from said mixing vessel, said closed vessel housing a filter device and means for introducing a controlled amount of chemicals into the waste water.
Abstract:
A waste disposal system for a combustion engine-powered vehicle includes means for sensing the temperature and speed of the engine and the level of waste in a holding tank. The system is activated only upon coincidence of predetermined inputs from the sensing means, to deliver the waste to an exhaust portion of the engine. Operation of the system is automatically prevented during the absence of any one of the predetermined inputs.
Abstract:
1. A portable waste disposal system comprising a housing; barrier means dividing said housing into first and second chambers; said first chamber having an inlet for receiving waste matter; first means in said first chamber positioned adjacent said inlet for depositing liquid waste matter in said first chamber, said first means being comprised of a porous member positioned beneath said inlet for retaining and supporting solid waste and permitting liquid waste to pass therethrough so as to be collected upon the floor of said first chamber; said first means further comprising second means for conveying solid waste matter into said second chamber, said second means further including means for rotating said porous member towards said second chamber to deposit therein solid waste matter collected upon said porous member; said second chamber having a pool of molten material; third means for heating said pool of molten material to an elevated temperature, said barrier means being comprised of a normally vertically aligned rotatable barrier plate coupled to said rotating means for moving said barrier plate to a horizontal position to provide sufficient clearance for said porous member to enable the same to transfer solid waste matter into said second chamber whereby said pool of molten material combusts solid waste matter deposited thereon.
Abstract:
A water closet and digester are parts of a sewage disposal unit that includes filter beds, tanks for bacterial action, and a recirculating flushing water line. The solid wastes can be disintegrated by a mascerator. In one embodiment the mascerator applies pressure to the waste by using motor driven rollers having flexible surfaces.
Abstract:
A system and method for utilizing and disposing of carbonaceous waste products accumulated aboard a spaceship, including human body generated wastes and other carbonaceous wastes, by processing the waste products into rocket propellants and utilizing such propellants for spaceship propulsion. The propellant compositions thus formulated are characterized by the presence of one or more fuel constituents and one or more inorganic oxidizer constituents (e.g., ammonium nitrate) in homogeneous admixture with the human body generated waste materials (e.g., human excrement).
Abstract:
A sewage treatment system particularly adapted for use in small boats, in which an additive for treating the sewage is stored in dry form, such as in tablets, in a tank separate from, but in communication with, the sewage treatment chamber. Flushing a toilet associated with the system automatically activates a water pump and causes water to be pumped from a separate source into the additive tank, dissolve a portion of the additive and flow, such as by gravity, from the tank into the treating chamber. At the same time a combination macerating and mixing unit is energized to reduce solid sewage to at least a maximum particulate size and vigorously mix and remacerate the reduced sewage with the dissolved additive flowing from the tank into the chamber.
