Abstract: A promoted activated carbon sorbent is described that is highly effective for the removal of mercury from flue gas streams. The sorbent comprises a new modified carbon form containing reactive forms of halogen and halides. Optional components may be added to increase reactivity and mercury capacity. These may be added directly with the sorbent, or to the flue gas to enhance sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The sorbent can be regenerated and reused. Sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active sorbent into the mercury contaminated gas stream are described.

Abstract: A vessel-based system and method for disposing of wastewater including bilge water from a bilge of the vessel. The system including a treatment unit for receiving and treating the wastewater to produce a substantially oil-free treated water and, an evaporator for receiving the treated water from the treatment unit. In an embodiment, the evaporator having an evaporation element for transferring heat to the treated water to evaporate the treated water.

Abstract: A method for processing wastewater includes the steps of introducing air and a liquid into a pump, and subjecting the air and liquid to high heat and pressure; delivering the heated and pressurized air and liquid from the pump to a gas and liquid separator to separate the air from the liquid; expanding the air from the gas and liquid separator through a nozzle to accelerate the air as it expands; injecting at least some portion of the wastewater to be processed into the air from the nozzle in an entrainment section downstream from the nozzle to entrain the wastewater into the air; passing the liquid portion from the gas and liquid separator through a valve to lower the pressure of the liquid to achieve flash evaporation of the liquid to produce water and steam; introducing the water and steam produced from the valve into the air and entrained wastewater in the entrainment section, to enhance entrainment of water into the air; and delivering the air and entrained wastewater from the entrainment section to an i

Abstract: Recently developed proceedures refine home septic tank effluent to a clean, odorless liquid, but the problem of daily disposal of hundreds of gallons of efflluent remains. Currently this fluid is emptied into the soil, a stream, or slow-evaporation ponds. Frequently, none of these methods are possible at an otherwise desirable homesite. Therefore, a compact, relatively inexpensive, and above all, quick acting process is needed.

Abstract: A residence (13) discharges its waste water into a septic tank (10). A pump (18) draws waste from the tank's liquid layer and feeds it to a distiller (22) as distiller feed. The distiller (22) divides the distiller feed into distillate and distiller residue. The distiller residue is returned to the septic tank (10), whereas the distillate is reused or discharged into a leach field. In either case, the adverse environmental effects of leach-field use are largely eliminated.

Abstract: The system for the recovery of water from urine aboard spacecraft includes a urine intake and pretreatment unit, a unit for water reclamation from urine and a condensate purification unit. The unit for water reclamation from urine is made on the basis of a rotary multistage vacuum distiller, each stage of which is formed by at least one heat-transfer plate and comprises an evaporation zone and a condensation zone. The stages of the distiller are separated from each other by separation plates, a chamber for collecting condensate and noncondensable gases being disposed downstream of the last stage and communicated with all the condensation zones of all the stages through water seals of condensate overflow and openings for the removal of noncondensable gases in disks mounted in the condensation zones.

Abstract: A method for processing sewage eliminates chemical "treatment", or, the addition of chemicals that are as harmful or more so to the environment as raw sewage. The method of processing sewage disintegrates the generally solid components of sewage into a highly de-moisturized powder via alternative processes of either (i) a freeze-drying process, or (ii) a combination centrifugal separation and an evacuated "bake-out" process, both which substantially drive out the vaporizable components of the sewage. In consequence, there are no resultant effluent and/or exhausting vapors from this method which would impact the environment.

Abstract: A retrofit system for biological treatment sanitation vaults wherein evaporation of the liquid waste is accelerated by locating a conduit within the waste receptacle into which only liquid may flow and evaporate within the conduit in the air flowing therethrough. A double conduit system substantially connected in parallel may be used to evaporate liquids accumulating in vaults receiving heavy use for short durations as a float operated air control system permits the most effective utilization of the air movement through the conduit circuit as automatically controlled by the liquid level.

Abstract: A liquid evaporator includes an air-tight outer container containing liquid therein, the liquid container having support legs adjacent the bottom surface thereof; an inner container mounted on the legs for partitioning the interior space of the outer container, the inner container having a wall made of insulating material; and a heater fixed to an upper portion of the outer container and positioned inside the inner container. The liquid evaporator may be combined with a deodorizing device for forming a urine treating device, wherein the urine treating device includes a deodorizing housing having an upper portion provided with a secondary heater therein, a catalyst surrounding the secondary heater, a blower provided outside the housing, and a diffusion pipe provided at the upper portion of the housing.

Abstract: Apparatus for treating living wastewater which purifies water to be treated such as living miscellaneous wastewater in general homes, human waste, urban drains and the like to evaporate and emanate the treated water into the atmosphere.The apparatus comprises a treating vessel for treating wastewater which is water to be treated, a sludge separating sediment layer filled into said treating vessel, a wastewater introducing pipe for introducing wastewater into said treating vessel, and a capillary suction type evaporation and emanation unit for evaporating and emanating the treated water into the atmosphere.

Abstract: A vacuum draft submerged combustion system and method for separating combustible hydrocarbons and other components or liquid solutions from their solvents, usually water, includes evaporating volatile components by a submerged combustion burner and condensing the vaporized volatile components under a partial vacuum. The hot gases from the burner are injected under partial vacuum into the first tank. The hot gases bubbled through the solution cause volatile components in the liquid to be evaporated and collected above the level of the liquid. The collected gasses are drawn into a condensing tank where the condensable particulates are condensed and collected.

Abstract: Apparatus for increasing the air/water interface of a body of liquid to increase vaporization that consists of a suction pick-up feeding liquid to a supply conduit which, in turn, is connected to a feeder pipe which distributes water down over an aeration assembly that is disposed proximate the body of liquid. The aeration assembly consists of a plurality of specialized cellular fiber panels arranged in any of a stationary linear array, rotatable radial array or horizontal spaced stack that are optimally wetted with the liquid to maximize contact with surrounding air.

Abstract: A continuous process and apparatus for drying aqueous solids by evaporation using a fluidizing oil and a surfactant wherein the fluidizing oil and surfactant are recovered and recycled separately or together. The aqueous solids may, or may not, have a heavy, natural oil associated with them.
