摘要:
A waste disposal system provides a mixing stage where waste matter is water-charged, the water charged mixture is then steam exploded by being sprayed onto a white hot surface in a chamber with only one outlet where the expansion on vaporization forces the vapor out through a chemical spray stage; next a vertical-filter stage removes and gravitationally drains coarse filtrate and finally a horizontal filter stage treats the vapor in the presence of a counterwash spray of fresh water before the vapor is released into the atmosphere; recirculation of the material filtered and treating materials is provided.

Process and apparatus for recovering clean water and essentially dry solids from dilute aqueous solids. A dilute stream of aqueous solids is concentrated by heat evaporation and the evaporated water is condensed and recovered. The concentrated aqueous solids are mixed with relatively non-volatile fluidizing oil and subjected to dehydration by heat evaporation. The steam formed in the dehydration step is used to supply heat for the concentration step. The solids are separated from the fluidizing oil and recovered in an essentially dry state while the fluidizing oil is recycled. If desired, a light, relatively volatile oil may be mixed with the dilute aqueous solids to prevent scaling and fouling in the concentration evaporator. The instant invention is thus characterized in that at least a portion of the heat energy of the steam formed by evaporation in the dehydration step is recovered as useful heat within the system.
摘要:
The present invention relates to a waste-management system; and more particularly to such a system that produces potable water. The disclosed waste-management system is adapted to be compacted to a size that fits onto a manually movable cart, or to be expanded to a size adapted to treat domestic and/or industrial waste. The overall system uses safe temperatures and pressures; and may therefor be utilized in many locations previously unavailable for such purposes.

Clear effluent from an aerobic sewage treatment tank is directed into one end of an elongated conduit adapted to be buried in the ground with the tank. The conduit has a length of many hundred feet and is preferably wrapped in the form of a substantially horizontal spiral coil. The opposite end of the conduit is vented to atmosphere, and a flow of air is directed from a supply pump through the conduit over the surface of the effluent to effect evaporation of the effluent into the air stream and discharge of the vapor with the air into the atmosphere. The air is directed into the conduit in a plurality of separate streams located at longitudinally spaced intervals and after moisture is removed from the air within a pressure-condensing container. The conduit is preferably formed of a corrugated flexible tubing of plastics material and may be constructed in a plurality of stacked coil sections which are connected in series.
摘要:
The treatment of wastes such as domestic sewage and the like by a method of and apparatus for handling the run-off from a septic tank or other separating unit including the evaporation and/or burning of the outflow of such unit. In the case of a septic tank the solids progressively settle in a series of connected tanks where the eventual run-off is a relatively clear liquid. It is proposed to heat this fluid, discharging the water vapour to the atmosphere, and subject any combustible gases that are present to an open flame. The liquid, heated in one or more stages to a high temperature, is preferably sprayed as steam or gaseous vapour into an open flame to further raise the temperature of the steam and to ignite and burn off the combustibles. The steam in part may then be condensed and drained off as mainly distilled water while the remaining gaseous vapours are treated to a second open flame to burn off any residual combustile volatiles, with the products of combustion and reheated steam or water vapour being discharged to the atmosphere.
