A method and system for decreasing the concentration of at least one metal in an aqueous solution. The metal may be molybdenum, tungsten, or both. An aqueous solution is introduced into at least one reaction zone, and at least one source of hydroxide ions is provided into the at least one reaction zone in an amount sufficient to precipitate at least some of the mass of the at least one metal. The aqueous solution includes a mass of the at least one metal and a mass of at least one reducing agent. The at least one reducing agent includes at least ferrous iron from at least one source of the at least one reducing agent. A composition of tungsten ferrite or molybdenum tungsten ferrite may be formed. The method may be used for purifying water, for the refining of metals, or to facilitate a chemical analytical determination.

A method for treating silicone emulsion waste includes the steps of adding base chemical materials to the silicone emulsion waste in an amount effective to cause separating of the silicone emulsion waste. The added chemicals separate the silicone emulsion waste into silicone oil and an emulsion-free water. The components can be separated, with the silicone oil laden liquid being sent to an incinerator and the emulsion-free water being sent to a wastewater treatment plant. The base chemicals can include sodium hydroxide, sodium carbonate, sodium chloride and/or combinations thereof. To enhance separating of the silicone emulsion waste, the silicone emulsion waste can be heated prior to the addition of the chemicals. Also, by recycling the treated water and adding the same to the silicone emulsion waste and base chemicals separation of the silicone emulsion waste can be enhanced.

An electrolyte solution containing an alkylene glycol and a chloride salt is useful for electropolishing metal substrates. An electropolishing method using the electrolyte solution is effective for polishing a varied of metals, including titanium and noble metals. The method avoids the handling and disposal challenges associated with previous methods using etching solutions containing hydrofluoric acid. A method of recycling the spent electrolyte solution is also described.

Methods, systems, and processes are disclosed for determining emissions outputs. One method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. The energy usage information and the emissions information is acquired as each occurs in real time. The method reports emissions outputs based upon the acquired real time information. Another method communicates with a communications network and acquires at least one of energy usage information associated with sources of emissions and emissions information associated with sources of emissions. This embodiment stores the acquired information as each occurs in real time. Emissions outputs are reported for the industrial process, the emissions outputs based upon the acquired real time information.

A method of removing silicone oils from waste water generated by a silicones manufacturing plant including the step of centrifuging the waste water to concentrate silicone oil contaminated solids while removing the silicone oils. The silicone oil contaminated solids are then dried in a continuously mixed sludge dryer to remove more silicone oils from the sludge to form a sludge product which comprises at least 10% water and a low silicone oil concentration.

A steam-generation management system remotely measures amounts of utility used by steam-generating systems; monitors and compares their performance against benchmarked performance; analyzes and determines causes for variances in their performance; and recommends to the steam user actions for achieving optimum operation. The steam-generation management also permits remote access and interaction by the user and allows for integrating steam-related information into an overall strategy for managing steam and energy supply.

System and methods for remote management of steam generating systems

The appliance comprises a container for receiving the soiled articles, a circulation pump for distributing a hot liquid to the container, a drain positioned in the container and connected to the pump for emptying the liquid from the container upon completion of a cycle and a hydroclone connected to the drain and the pump, for removing soil from the liquid such that about ninety percent (90%) of the liquid distributed to the container during one cycle can be utilized during at least one subsequent cycle. Another embodiment includes a dishwasher having a normal operating cycle, the dishwasher comprising a container for accommodating a plurality of articles, a circulation pump for delivering a liquid to the container and for circulating the liquid within the container, a diverter connected to the circulation pump for diverting at least a portion of the circulating liquid to a hydroclone while returning at least about ninety percent (90%) of the liquid diverted to the hydroclone to the circulating liquid, the returned liquid having at most about 0.02% solids contained therein.

The present invention is directed towards a system that makes high quality gypsum from a dry flue gas desulfurization process which utilizes a low temperature regeneration of the carbon adsorbent in the flue gas process. The high quality gypsum is easily filterable with large crystal size and has high purity with few contaminants, such as calcium sulfite and heavy metals. This invention is also directed towards a system that regenerates the carbon used in dry flue gas desulfurization at a temperature below 120.degree. C. and the recycling of sodium hydroxide to form a sodium sulfite reducing solution for carbon adsorbent regeneration.
