摘要： Processes and apparatuses for separating ions from an aqueous solution are provided which utilize a first separation by an ion exchange medium in combination with second separation by a D.C. electropotential gradient. The first separation separates the target ion by ion exchange and the second separation effects migration of the ions from the ion exchange medium, through a ion permeable, hydrophobic membrane into a second zone, which may contain a buffer. The hydrophobic membrane substantially resists fouling.

摘要： Remediation of soil and groundwater using electropotential gradient induced migration of a target ion and immobilization and/or confinement of the target ion by a host receptor matrix (HRM). In addition to immobilizing and/or confining the target ion, the HRM can comprise a buffer or an ionizable species which releases an exchange ion during application of the electropotential gradient. The exchange ion, when less mobile than a (H.sup.+) ion or hydroxyl (OH.sup.-) ion, increases the efficiency of energy usage during decontamination. The exchange ion can also perform other tasks in the vicinity of the electrodes which improve the decontamination process. The host receptor matrix also can comprise a material which is water impermeable and which has a low surface energy, such as a layer of polytetrafluoroethylene film. When such a material is used, the host receptor matrix can comprise a receptacle in which there is a liquid and/or solid composition which immobilizes and/or contains the target ion.

摘要： Processes and devices are disclosed for converting an aqueous waste solution, such as a radioactive waste stream, into a highly concentrated sludge having substantially little or no water. In turn, the sludge may be converted into a solid polymeric form suitable for storage. The processes utilize a carrier liquid which has a boiling point higher than that of water, and which facilitates the transfer of heat to the water to vaporize the water into steam. A subsequent separation of the dewatered solution yields the highly concentrated sludge.

摘要： Methods for the encapsulation and solidification of waste material, particularly radioactive ion exchange resin bead media, are provided along with the apparatus to accomplish the methods, and the final encapsulated storage article. The ion exchange resin is solidified within a containment vessel by the addition of a thermosettable polymeric binder without the need for a pre-mixing vessel. The resulting exothermic conditions occasioned by the curing of the polymer are controlled by the sequential delivery of the polymeric binder, preferably through an injection lance.

摘要： Applying a desorbing wave energy to a soil matrix can effect desorption of ionic species which are associated with the matrix. This method is especially applicable to decontamination of soils to which metals and/or radioactive isotopes are adsorbed. The desorbing energy may be microwave energy, sonic or ultrasonic energy, etc., or combinations thereof. An electromagnetic potential also can be applied to the matrix to enhance desorption and or migration of the species. An electrolyte also may be added to the matrix to enhance desorption and or migration of the species.

摘要： An augmentation amplifier is provided for aspirating gas flow from a surrounding medium. The amplifier connects at an inlet to a pressurized gas source and at an outlet to a gas receiver. Ambient gas from the medium supplements source provided compressed gas. The amplifier includes a Venturi conduit including a throat, an external cavity and a diffusion chamber. The conduit receives and flows pressurized gas from the inlet to the throat. The cavity receives ambient gas from the medium. The chamber expands and accelerates the pressurized gas from the throat to entrain the ambient gas via aspiration. The accelerated and ambient gases combine into an exhaust gas to the outlet.
