International Classification:

US Classification:

210/151000, 210/096100, 210/097000, 210/199000, 210/220000, 210/610000, 210/621000

Abstract:

A improved activated sludge system and method for treating wastewater containing contaminants is disclosed which offers a broad array of advantages over conventional activated sludge wastewater treatment systems, including smaller size, higher rates of operation, higher oxygen transfer efficiency, lower operating costs, and a substantially decreased level of excess sludge production. The improved activated sludge waste treatment system of the present invention has two processing tanks rather than the several tanks that are commonly found in activated sludge systems for treatment and sludge management equalizations, including anaerobic processes. The first processing tank is a contact tank which hosts a reaction which functions not merely to digest the maximum amount of contaminants, but instead to bind contaminants to the microorganisms through absorption, adsorption, precipitation, or digestion so that they can then be removed from the liquid in a solid/liquid separator. The activated sludge removed by the solid/liquid separator is then supplied to a digester tank containing a high concentration of activated sludge, where virtually complete digestion is achieved to minimize the volume of solids remaining. Activated sludge is provided from the digester tank to the contact tank to facilitate the reaction in the contact tank.

International Classification:

B01D 1302

US Classification:

204301

Abstract:

A method of producing a sol of an element selected from the group consisting silicon, aluminum, antimony, chromium, manganese, molybdenum, tin and tungsten comprising electrodialytically transferring alkali metal cations of an aqueous solution of a water soluble alkali metal salt of the oxide of the said element from an anode compartment of an electrolytic cell to a cathode compartment of the electrolytic cell while essentially preventing the migration of the metal oxide into the cathode compartment by positioning a cation permselective membrane between the anode compartment and the cathode compartment while carefully and continuously controlling the pH of the solution and removing the so-produced sol from the anode compartment of the electrolytic cell as well as a novel electrodiayltic cell for sol formation.

Assignee:

Diamond Shamrock Corporation - Dallas TX

International Classification:

C25B 116
C25B 126

US Classification:

204 98

Abstract:

Concentrated alkali metal hydroxide substantially free of alkali metal halide and other impurities is produced by the electrolysis of an alkali metal halide solution in an electrolytic cell having a dimensionally stable anode and a metal cathode separated by an electrically conductive stable selectively permeable hydrated cation ion-exchange membrane film of a fluorinated copolymer having pendant sulfonic acid groups or derivatives of such groups. The membrane film is capable of use at high temperatures and under severely corrosive chemical conditions for extended periods without degradation.

US Classification:

204 87

Abstract:

An alkali metal carbonate substantially free of alkali metal chloride is efficiently produced by electrolyzing an alkali metal chloride in an electrolytic cell having anolyte and catholyte compartments separated by a cation-exchange hydraulically impermeable membrane comprised of a thin film of a fluorinated polymer having pendant carboxylic acid or alkali metal carboxylate groups and a cathode spaced apart from the membrane, injecting into the catholyte compartment of the cell carbon dioxide in a quantity sufficient to convert substantially all the alkali metal hydroxide forming therein to the alkali metal carbonate salt, and utilizing a magnitude of electrolyzing current that reduces alkali metal chloride in the catholyte solids to less than 400 ppm.
