Abstract: The invention relates to a method for cleaning liquids containing impurities. Adsorbents are added to the liquid, which adsorb the impurity. Several particles of adsorbent are agglomerated with the impurities adsorbed therein/thereon to form greater particles of adsorbent. The now greater particles of adsorbent are suspended in the liquid once again. The liquid containing the greater particles of adsorbent is then filtered. An apparatus possesses at least one agglomerator with a feed inlet, an outlet each for the separated components (clear runnings, concentrated suspension) and an apparatus for producing the agglomeration. The latter is preferably an apparatus for producing an electric field. A pressure filter with a feed inlet for the concentrated suspension and an outlet each for the separated components is further provided.

The method comprises contacting a suspension comprising a non-conducting liquid silicon containing compound and a particulate having a different dielectric constant than the non-conducting liquid silicon containing compound with a non-conducting packing substrate in an electric field. The present method is especially useful for removing suspended particulate ranging in size from about 0.01 to 100 microns from silicon fluids.

Abstract: An electrostatic fluid filtration system of the present invention is designed to remove contaminants from liquids thereby refreshing their functionality and extending their useful life. This system reduces to commercial practice a myriad of partially attained and less efficient techniques of filtration by focusing upon economic, environmental, and health factors as well as simplicity of manufacture, use and maintenance. Several generic embodiments are identified for cooking oils, fuels, lubricants and solvents, all of which have been successfully demonstrated in commercial operating environments. Proven magnetic and electrostatic phenomenologies are integrated in a controlled system that is electronically and physically adaptable to the viscosity and dielectric properties of various fluids as well as contaminant characteristics.

Abstract: An electrostatic filter utilizes two separate filter cartridges in a parallel flow configuration with respect to incoming dielectric fluid containing particulates. Each cartridge is connected to opposite sides of a high voltage power supply, resulting in the electrodes contained in one of the cartridges having an opposite polarity than the electrodes contained in the other cartridge. This, in turn, results in having the fluid borne particulates exiting one cartridge being charged oppositely to those exiting the other. The fluid streams exiting the two cartridges are joined together, allowing the particulates to flocculate. These larger groupings of particulates may then be mechanically filtered in a third cartridge. The parallel flow configuration results in an electrostatic filter that is relatively insensitive to water contained in the dielectric fluid.

Abstract: The invention provides fittings for the ends of electrochromatography cols. Each fitting includes an annular electrode surrounding one end of the passage electrical fields to be applied. The fitting also contains a passageway for eluant flowing into or out of the column, an annular chamber for the electrode and a membrane separating the passageway from the annular electrode chamber. The membrane prevents gases and electrolytic products from entering the column eluent going through the chromatographic column. The membrane also isolate the electrodes from the compounds such as proteins and macromolecules being separated. A buffer solution was pumped through the electrode chamber to remove the gases and electrode products. The buffer flow through the electrode chamber maintains a constant pH and conductivity so that the electrical field applied by each electrode is constant. The buffer flow also serves to remove the heat generated in the electrode chamber.
