Abstract
A sewage disposal plant for treating raw sewage. The plant has an enclosed tank with a heating element for evaporating or vaporizing the raw sewage, including solids and liquids. The sewage vapor is conveyed to another unit for condensing the vapor to an unpolluted liquid, suitable for disposal in a stream or other body of water.
Claims12
A method for disposing of a batch of sewage, comprising:
- a. feeding a batch of sewage into a tank having a removable top and containing a heater means in the upper portion thereof free of the removable top;
- b. heating the batch of sewage with the heater means to evaporate water of said batch and further to incinerate solid material of said batch remaining after evaporation of the water, so as to produce a powdery residue therefrom;
- c. feeding water vapor from the tank to a condenser means comprising (I) an inlet through which water vapor enters the condenser means, (II) an outlet through which condensed water vapor exits from the condenser means, and (III) a quantity of particulate material sufficient to condense water vapor from said batch by absorbing heat therefrom;
- d. withdrawing and disposing of water exiting from the outlet of the condenser means;
- and
- e. withdrawing and disposing of powdery residue in the tank.

A batch method of sewage disposal in a building such as a home or apartment, comprising:
- a. feeding a batch of raw human sewage, including feces and urine, deposited in a plumbing fixture in the building, into the confined chamber of a tank located remote from the plumbing fixture, the tank having a removable top for sealing the chamber and a heater means disposed in the upper portion of the chamber free of the removable top;
- b. heating the batch of sewage with the heater means to evaporate water of said batch and further to incinerate solid material of said batch remaining after evaporation of the water, so as to produce a powdery residue therefrom;
- c. removing the water vapor from the chamber and feeding it to a condenser means comprising (I) an inlet through which water vapor enters the condenser means, (II) an outlet through which condensed water vapor exits from the condenser means, and (III) a quantity of particulate material sufficient to condense water vapor from said batch by absorbing heat thereform;
- d. withdrawing and disposing of water exiting from the outlet of the condenser means;
- and
- e. withdrawing and disposing of powdery residue in the tank.
3 more elements
A system for disposing of a batch of sewage, comprising:
- a. a closed tank with a removable top, the tank functioning to contain a batch of sewage to be disposed of;
- b. inlet means cooperating with the tank and functioning to feed said batch of sewage into the tank;
- c. heater means mounted in the tank in an upper portion thereof free of the removable top, the heater means functioning to evaporate water of said batch and further to incinerate solid material of said batch remaining after evaporation of the water, so as to produce a powdery residue therefrom;
- d. vapor outlet means cooperating with the tank and functioning to remove water vapor produced by evaporation of the water;
- e. means for condensing the water vapor, including (I) an inlet through which water vapor enters the condenser means, (II) an outlet through which condensed water vapor exits from the condenser means, and (III) a quantity of particulate material sufficient to condense water vapor from said batch by absorbing heat therefrom;
- and
- f. conduit means cooperating with the vapor outlet means and functioning to feed water vapor to the inlet of the condenser means.

A batch system of sewage disposal in a building such as a home or apartment, comprising:
- a. a closed tank coupled by piping to at least one plumbing fixture in which a batch of raw human sewage, including feces and urine, is deposited, the tank located remote from the plumbing fixture and including a confined chamber for containing said batch of sewage and a removable top for sealing the chamber from the ambient atmosphere;
- b. heater means mounted in the chamber in an upper portion thereof free of the removable top, the heater means functioning to evaporate water of the sewage and further to incinerate solid material of the sewage remaining after evaporation of the water, so as to produce a powdery residue therefrom;
- c. inlet means cooperating with the tank and functioning to feed said batch of sewage from said piping into the chamber;
- d. vapor outlet means cooperating with the tank and functioning to remove water vapor from the chamber;
- e. means for condensing the water vapor, including (I) an inlet through which water vapor enters the condenser means, (II) an outlet through which condensed water vapor exits from the condenser means, and (III) a quantity of particulate material sufficient to condense water vapor from said batch by absorbing heat therefrom;
- and
- f. conduit means cooperating with the vapor outlet means and functioning to feed water vapor to the inlet of the condenser means.
