摘要： Volatile organic compounds, including, in particular, the BTEX group, present in wastewater and groundwater in concentrations of about 1.0 PPM to 100 PPM, may be removed by adsorption onto a polymer coated porous substrate. The substrate is preferably selected from a group consisting of mullite, diatomaceous earth and ground structural brick and fire brick. The polymer coatings may be applied by immersing the substrate in a solution of the polymer or the polymer coating may be generated on the substrate by polymerization of a substrate coated resin. Polystyrene, polypropylene glycol, polymethyl silicone, polyesters and polyurethanes may be used as the coating material. The adsorbent composition may be disposed in a packed column, as a liner for storage pits, as a barrier for surface bodies of water and groundwater flow, and may be regenerated or disposed of by deep well injection.

摘要： An apparatus for treating a fluid to remove at least part of a component or components from the fluid in a reciprocating flow ion exchange system. The apparatus includes a vessel having a central holding chamber that is enclosed at each end by an end cap. A packed bed of ion exchange particles is held within the central holding chamber through the use of upper and lower retaining means so that a particle free cavity is created above and below the particle bed. The flow of fluid is distributed substantially evenly across the end of the particle bed by the pressure drop through the bed when one of the particle free cavities is filled with pressurized fluid.

摘要： A demand initiated method for regenerating a water softener which operates the softener ion exchange bed over a capacity range in which the resin is most efficiently restored by exposure to brine. The reserve capacity of the softener is adjusted in response to the amount of softening capacity used since the last regeneration, as is the quantity of saturated brine to be used for the next regeneration, which is scheduled when the reserve capacity is exceeded, or the remaining available capacity will not be adequate for normal usage on the next day of the week.

摘要： A method of separating and recovering Pu and Np from a Pu- and Np-containing nitric acid solution. The method comprises the steps of subjecting a nitric acid solution containing Pu and Np to valence adjustment by adding a reducing agent consisting of hydroxylamine nitrate and hydrazlne to said nitric acid solution so as to reduce Pu and Np in said nitric acid solution to Pu (III) and Np (IV), respectively; adjusting a nitric acid concentration of said nitric acid solution after said valence adjustment to 6 to 8 M; bringing said nitric acid solution after said nitric acid concentration adjustment into contact with a strong basic anion exchange resin so as to cause Np to be selectively adsorbed by said resin and to separate and recover Pu as a plutonium nitrate solution; and eluting said adsorbed Np (IV) by using diluted nitric acid of 1 M or below so as to recover Np as a neptunium nitrate solution. The valence adjustment step may be carried out by subjecting the Pu- and Np-containing nitric acid solution to electrolytic reduction instead of using the reducing agent.

摘要： A process for impregnating zeolite with a quaternary ammonium cation (QAC) and then coating the impregnated zeolite with permanganate (such as potassium permanganate), and for impregnating zeolite with permanganate and then coating the impregnated zeolite with a QAC, and coated, impregnated zeolite crystals resulting from either process. Either coating acts as a protective agent for the impregnating substance in each zeolite crystal's interior, and allows regulated time release control of the impregnating substance, thus permitting a controlled diffusion (or absorption) rate in applications in which the coated, impregnated zeolite is employed to absorb contaminants from air or water. Combinations of coated and uncoated zeolite crystals can be chosen to match specific environmental circumstances calculable by analysis of the air or water to be treated. Mixtures of coated and uncoated QAC-impregnated zeolite can be used to react with organics such as benzene, toluene, and xylene, uncoated zeolite impregnated with permanganate, and mixtures of coated and uncoated permanganate-impregnated zeolite can be used to react with hydrogen sulfide, acetone, ethylene glycols, formaldehyde, and other contaminants. Other embodiments of the invention are methods for producing zeolite crystals impregnated with manganese dioxide, and for using such manganese dioxide-impregnated crystals to absorb contaminants from fluid.
