摘要:
The system and device of the present invention is a technology designed to meet the biological nutrient removal requirements for the treatment of sanitary and municipal wastewater, storm water run-offs and other biologically contaminated water. This technology dies not require the addition of water treatment chemicals. The treatment process of the present invention removes BOD loading, converts nitrogenous loading to nitrates, removes the nitrates, phosphorus and kills coliform and other bacteria, as well as parasites and fungi.

Treatment compositions and a method are provided for the removal of a plurality of heavy metals and radioactive isotopes from wastewater. The treatment compositions comprise an alkali; adsorbents, such as montmorillonite and illite clays; catalysts, such as polyelectrolytes and sodium carbonate; one or more flocculants, such as a metal salt and calcium hydroxide; zirconium as a chelating and complexing agent; and boron as a neutron absorbent. The selected composition is introduced into and mixed with the wastewater, which is then filtered to produce a sludge containing the contaminants.
摘要:
The present invention provides compositions and a method to remove a plurality of radioactive isotopes and/or heavy metals simultaneously from water or wastewater. The compositions comprise lattice clays; flocculants; a neutron absorbent; catalysts; and a setter. The selected compositions is entered into a vessel and agitated with the water to produce a sludge containing the contaminants.

An apparatus for separating and recovering effluent gases from a furnace includes a pressure vessel for containing the gases. This vessel has a fluid input for receiving the gases and a fluid output for selectively removing the gases when they are separated. A condenser is provided to transform and maintain the lowest vapor pressure gas as a liquid so that it accumulates as a liquid at the bottom of the vessel. The remaining non-condensed effluent gases accumulate in strata above the liquid. Apparatus is provided to selectively remove the liquid and at least one of the remaining non-condensed gases from the vessel through the fluid output. Also set forth is a method for recovering effluent gases from a furnace including the steps of adding the gases to a pressure vessel, altering the density of the gases so that the lowest vapor pressure gas condenses into a liquid and the non-condensed gases stratify above the liquid. Then the liquid is removed from vessel and optionally expanded to cool the vessel. Finally, at least one stratified non-condensed gas is selectively removed from the vessel.

An emissionless furnace boiler and effluent gas recovery system includes a pressure vessel having a fluid input and fluid output. The system is capable of maintaining an entropy characteristic equal to at least the condensing pressure of the lowest entropy gas of the gases constituting a processed effluent gas discharge. There is also provided a hollow, annular jacket having a surface in thermal communication with the pressure vessel, the jacket having an axis in substantial alignment with the gravity vector and the jacket including a fluid input and fluid output. The system also includes a fluid path beginning internally of said pressure vessel, passing through the vessel, through the fluid output means, continuing externally of the vessel, and extending between the vessel and the input of the jacket. Within the fluid path, but prior to the input of the jacket, there is provided an expansion valve for selectively changing the volume of fluid flowing from the vessel prior to its entry into the jacket. The system yet further includes a compressor having an input in fluid communication with the output of the annular jacket, the compressor itself having an output in fluid communication with the input of the pressure vessel.
摘要:
A treatment composition and method is provided for removing a plurality of contaminants from a wastewater system in the form of a nonleachable sludge. The treatment composition comprises an alkali or alkaline carbonate; activated montmorrilonite; a catalyst, such as zirconium and polyelectrolyte; one or more flocculants, such as a metal salt and calcium oxide, lime, or calcium hydroxide; and bentonite. Additionally, the treatment composition may contain soda ash, lignite, and activated carbon. The treatment composition is introduced and mixed with the wastewater, which is then filtered to produce a sludge containing the contaminants in a nonleachable form.
