Abstract: Disclosed herein are systems and methods method of treating wastewater. The method comprises measuring total organic carbons (TOC) in a stream of wastewater (202) from a processing plant (204), wherein the TOCs are measured in the stream of wastewater (202) at an inlet to a flotation thickener (208), providing the measured TOC's to a processing device (210), determining, based on the measured TOCs in the stream of wastewater (202), a treatment protocol for the stream of wastewater (202), and treating the wastewater stream (202) by controlling a feed control unit (212) in accordance with the determined treatment protocol.

Abstract: Stabilized quadrivalent cation oxide electrolytes are employed in fuel cells at elevated temperatures with a carbon and/or hydrogen containing fuel anode and an oxygen cathode. The fuel cell is operated at elevated temperatures with conductive metallic coatings as electrodes and desirably having the electrolyte surface blackened. Of particular interest as the quadrivalent oxide is zirconia.

Abstract: Oxygen bearing compounds, such as those contained in exhaust gases from an internal combustion engine, including NO and NO.sub.2 (NO.sub.x), CO, CO.sub.2 and SO.sub.2 are catalytically decomposed by use of a solid electrolyte comprising a stabilized oxygen-ion oxide. The electrolyte is in the form of a thin member, or film, across the thickness dimension of which an electric field is applied by use of electrodes at opposite faces thereof. A d-c voltage source is connected to the electrodes for generation of a unidirectionalelectric field through the electrolyte. In accordance with the present invention, means are provided for limiting current drain from the voltage source to a negligable amount such that catalytic dissociation is effected substantially without the consumption of electrical power.

Abstract: A low pressure process for the production of beta-lithium aluminate (LiAlO.sub.2) in a two thermal stage reaction of alumina with liquid phase lithium carbonate comprising admixing powdered alumina with a carbonates composition selected from the group consisting of a ternary lithium-potassium-sodium carbonates composition, a binary lithium-potassium carbonates composition and a binary lithium-sodium carbonates composition, heating the admixture at about 480.degree. to 550.degree. C. in a first thermal stage for a period of time to react the alumina with lithium carbonate to form lithium aluminate, and raising the temperature of the lithium aluminate to about 600.degree. to 650.degree. C. in a second thermal stage for a period of time to transform the lithium aluminate (LiAlO.sub.2) to the desired beta-lithium aluminate.
