  • Patent number: 5634281
    Abstract: An apparatus for drying moist solid or semi-solid materials, such as sewerage sludge, municipal waste, industrial waste, agricultural waste, and the like, includes a dryer unit having a plurality of stacked heating chambers, each of the heating chambers above the lowest heating chamber having a conveyor belt for transporting the material through the associated heating chamber and depositing it on a lower heating chamber, the lowest of the stacked heating chambers including a conveyor belt for transporting the material therethrough and discharging the material from the dryer unit. The apparatus utilizes a combination of convective heat transfer, in the form of a heated gas which rises upwardly through the dryer unit through successive heating chambers, and radiative heat transfer, provided by radiative heating units disposed above the conveyor belt in each heating chamber.

  • Patent number: 5143626
    Abstract: The invention discloses an apparatus and process for destroying pathogens and dehydrating streams of waste in one, continous process. More particularly, the invention contains an auger with specially modified, variably angled blades which agitates a stream of waste. Also, contained in tandem with the auger, a series of variably angled infrared radiate elements are positioned above the augar exposing the moving stream of waste to radiation. Thus, as the waste stream is transported along, the auger blades continually expose the waste stream to the radiation, thereby killing the entrapped pathogens and evaporating the insitu water. Further, the auger and infrared radiation heater elements are encased in a sealed trough, thus sealing in the heat being generated by this process. By sealing the trough, the heat provides excess energy to aid in destroying pathogens and evaporating the insitu water contained in the waste stream, until the water content is less than or equal to five per cent (5%) by unit volume.

  • Patent number: 4536286
    Abstract: A packaged, transportable waste treatment system for hazardous and non-hazardous wastes comprises a pair of mixing tanks having a flow inlet at the lower bottom central portion of the tanks, the flow inlet providing an injection conduit which proceeds vertically a distance into one of the tanks. A floc concentration tube is provided with an inner bore, the tube being vertically mounted in the tank about the injection conduit with the tube having a lower fluid inlet and an upper fluid outlet, the fluid inlet being in communication with the tank by means of a plurality of perforations in the tube at the fluid inlet adjacent the bottom of the tank. A rotatable propeller shaft having a mixing propeller mounted thereon is attached to the tank structure, the shaft being mounted at least in the tube bore above the injection conduit with the propeller being between the lower fluid inlet and the upper outlet immediately adjacent the outlet of the injection conduit.
