US Patent:

6685834, Feb 3, 2004

Filed:

Dec 20, 1999

Appl. No.:

09/467814

Inventors:

Sudhir N. Murthy - Reston VA
R. David Holbrook - Blacksburg VA
John T. Novak - Blacksburg VA
Sun-Nan Hong - Cary NC

Assignee:

Kruger, Inc. - Cary NC

International Classification:

C02F 300

US Classification:

210613, 210631, 210727

Abstract:

A Method of treating sludge prior to dewatering by mixing with the sludge a cationic metal in the form of an iron or aluminum slat along with a cationic polymer. The addition of the iron or aluminum salt substantially reduces the amount of polymer required for acceptable dewatering, thusly significantly reducing the cost of the dewatering process. The method is enhanced by subjecting the prior digested sludge to mesophilic aeration prior to the cationic metal salt and polymer being added.

International Classification:

C02F 3/00

US Classification:

210605

Abstract:

An improved process for sludge treatment includes anaerobic digestion followed by post-mesophilic aerobic and/or anoxic digestion. The first anaerobic step may be performed under either mesophilic or thermophilic conditions. The subsequent aerobic/anoxic digestion may be performed using either simultaneous, sequential or pulsed aerobic and anoxic conditions. An apparatus for performing the improved sludge treatment may be one digester for performing the anaerobic followed by aerobic/anoxic digestion. Alternatively, the system for performing the improved sludge treatment techniques may be at least two digest reactors.

Filed:

Apr 3, 2001

Appl. No.:

09/825473

Inventors:

Michael Glazov - Pittsburgh PA, US
John Novak - Baton Rouge LA, US
Alexey Vertegel - Moscow, RU

International Classification:

B01J021/04

US Classification:

423/628000, 502/303000

Abstract:

Thermally stable transitional alumina particulates retaining high specific surface area after calcination at 1000 C. suitable for the use as catalysts or catalysts supports are produced by treating an aqueous solution containing Al and optionally a doping amount of La (e.g., 0.3 mol. %) with an anion-exchange resin to give a stable hydroxide sol followed by freeze drying of the sol and further thermal dehydration. The resultant stabilized transitional alumina retains high specific surface area at 1000 C., and additionally stabilization is achieved at very low levels of added La.

Appl. No.:

7/090880

Inventors:

Robinson P. Khosah - Point Breeze PA
John W. Novak - New Kensington PA

Richard R. Burr - Leechburg PA

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

B01D 1508

US Classification:

210635

Abstract:

Disclosed is a method of separating organic or organometallic materials under supercritical fluid conditions, the method comprising the steps of providing a bed of packing material selected from a metal oxide/hydroxide support material having phosphorous-containing organic molecules bonded to reactive sites on said support material, alumina and alumina-containing mixtures. The materials are introduced to the bed and a fluid is added to the bed under supercritical fluid conditions. The fluid removes one of the materials from the bed.

Appl. No.:

6/769132

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

B22D 1914

US Classification:

164 97

Abstract:

A method for bonding aluminum and aluminum alloys to refractory materials. A body of metal is heated to an elevated temperature at a total pressure above the vapor pressure of aluminum but less than atmospheric pressure. Oxygen partial pressure is maintained sufficiently low to prevent substantial oxidation of the metal. The heated body is contacted with a mass of refractory material and cooled, thereby forming a composite.

International Classification:

C02F 142

US Classification:

210684

Abstract:

A method is disclosed for reducing the amount of a first contaminant and second contaminant in a solution to environmentally safe levels, said solution having a substantially greater amount of the first contaminant than the second contaminant. The method comprises: contacting the solution with an activated or calcined product of a compound having the formula A. sub. 6 B. sub. 2 (OH). sub. 16 C. 4H. sub. 2 O, wherein A is a divalent metal cation, B is a trivalent metal cation and C is a mono- to tetravalent anion. The method further comprises separating the solution from the contacted product. The method is particularly useful for removing both selenium and sulfate, arsenic and sulfate, or arsenic and phosphate from a waste water stream. An unpredicted preference for selenium and arsenic, in the presence of other contaminants including sulfate and phosphate, was also shown herein.

International Classification:

B01J 2022

US Classification:

502401

Abstract:

A chromatographic packing material is disclosed comprising a metal oxide/hydroxide particle having chemically bonded to reactive sites on a surface thereof, a monolayer of one or more phosphonic acids. The bond to the metal oxide/hydroxide surface is formed by reaction of the phosphorous-containing group of the phosphonic acid with the metal oxide/hydroxide surface, so that the carbon-containing or non-polar group of the phosphonic acid is oriented away from the metal oxide/hydroxide surface.

International Classification:

C02F 128

US Classification:

210662

Abstract:

An improved process is disclosed for the purification of an impure aqueous solution containing heavy metal ions which comprises passing the impure solution through a bed of activated alumina adsorbent. The heavy metal ions are removed from the impure aqueous solution by adsorption onto the activated alumina adsorbent. The adsorbent may be regenerated for reuse and the adsorbed metals recovered by subsequently stripping the metal ions from the adsorbent and recycling the metal ions back to the process of origin. The pH of the effluent may be monitored to determine when the capacity of the adsorbent has been reached and regeneration of the adsorbent should be commenced. In a preferred embodiment, a portion of the activated alumina is pretreated with acid before passing the impure solution through the adsorbent to enhance the chromium ion adsorption of the acid-treated activated alumina and a portion of the regenerated activated alumina is again treated with acid after each regeneration cycle.
