Foam Separation

	Foam Separation Foam separation is a chemical process which falls into a category of separation techniques called " Adsorptive bubble separation methods".Adsorptive bubble separation methods, R. Lemlich (1968) Industrial and Engineering Chemistry, Vol. 60 (10) 16-29 It is further divided into froth flotation and foam fractionation Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam. It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums .... Foam separation is essential in order to prevent contamination of fermentation medium through the foam by external microbes. References Chemical processes {{chem-process-stub ...

	Chemical Process In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort. In an "engineering" sense, a chemical process is a method intended to be used in manufacturing or on an industrial scale (see Industrial process) to change the composition of chemical(s) or material(s), usually using technology similar or related to that used in chemical plants or the chemical industry. Neither of these definitions are exact in the sense that one can always tell definitively what is a chemical process and what is not; they are practical definitions. There is also significant overlap in these two definition variations. Because of the inexactness of the definition, chemists and other scientists use the term "chemical process" only in a general sense or in the engineering sense. However, in the "process (engine ...

picture info	Froth Flotation Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously. Industries Froth flotation is applied to a wide range of separations. An estimated 1B tons of materials are processed in this manner annually. Mineral processing Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity diffe ...

	Foam Fractionation Foam fractionation is a chemical process in which hydrophobic molecules are Separation process, preferentially separated from a Solution (chemistry), liquid solution using rising columns of foam. It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums; these units are known as "protein skimmers". However it has much broader application in the chemical process industry and can be used for the Continuous foam separation, removal of surface active contaminants from waste water streams in addition to the enrichment of bio-products. History Whilst protein skimmers have been common place in aquaria for many years, it was not until the 1960s that a concerted effort was made by Robert Lemlich of the University of Cincinnati to characterise a model of adsorptive bubble separation processes, of which foam fractionation is one example. Until the mid-2000s, there was very little further development of foam fractionation or attempts to understand the underlyi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
