43	Particle separator	US381477	1995-01-31	US5512171A	1996-04-30	Saleam Essop; Allen G. Bullard
This invention relates to a separator device for the separation of fine particles from a contaminated liquid. The device utilizes the process of electrolysis to produce small gas bubbles which attach themselves to the fine particles and move the particles to the top of the liquid surface where they can be easily removed. The separation is facilitated by the use of baffles which prevent the formation of convection currents in the body of the separator device, and by inclined plates which direct the rising particles towards the removal point.
44	Solids separator boundary layer effect filtration system	US188092	1994-01-28	US5451318A	1995-09-19	Jack Moorehead
A filtration system for water or other selected liquids that includes an ozone mixing station, a primary solids and gas separator and, if desired, a second vortex particle separator and filter system. The ozone mixing station includes a high efficiency ozone generator and a channel arrangement, such as a spiral tubular treatment coil, through which the ozone/liquid mixture passes to assure thorough mixing and provide time for effective treatment. The primary solids separator includes an offset inlet jet through which the liquid from the ozone treatment station is injected into a first circular chamber. The resulting rotating liquid vortex moves to a narrowed co-axial second circular chamber to cause heavy particles to concentrate at the outer perimeter then to a coaxial larger third circular chamber. The liquid exits through an annular outlet located around the chamber axis to prevent buoyant particles in the axial region and heavy particles at the outer periphery from passing out with the liquid. Gas collects in a cylindrical axial region with the lighter suspended particles in an annular region around the gas column. The gas phase is removed through an annular, variable, series of holes at the top of the chamber. The liquid from the solids separator may be passed to a filter system to further treat the liquid.

The invention relates to a method for measuring and adjusting electrochemical potential and/or component content in the process of treating valuable materials, when the valuable materials should be recovered either together or separately by aid of the values of the recovery range defined on the basis of electrochemical potential and component control. According to the invention, the measuring of electrochemical potential and/or component content is carried out by means of at least one electrode (4, 5), advantageously by means of a mineral electrode, so that in order to regulate the physicochemical state of the electrode and/or to remove the coating layer formed on the electrode surface and in order to protect the electrode, onto the electrode there is switched a supply voltage differing from the electrochemical balance potential of the electrode, which supply voltage is switched off before starting the measuring operation.

48	Flotation process for removal of precipitates from electrochemical chromate reduction unit	US645167	1975-12-30	US3989608A	1976-11-02	James R. DeMonbrun; Charles R. Schmitt; Everett H. Williams
This invention is an improved form of a conventional electrochemical process for removing hexavalent chromium or other metal-ion contaminants from cooling-tower blowdown water. In the conventional process, the contaminant is reduced and precipitated at an iron anode, thus forming a mixed precipitate of iron and chromium hydroxides, while hydrogen being evolved copiously at a cathode is vented from the electrochemical cell. In the conventional process, subsequent separation of the fine precipitate has proved to be difficult and inefficient.In accordance with this invention, the electrochemical operation is conducted in a novel manner permitting a much more efficient and less expensive precipitate-recovery operation. That is, the electrochemical operation is conducted under an evolved-hydrogen partial pressure exceeding atmospheric pressure. As a result, most of the evolved hydrogen is entrained as bubbles in the blowdown in the cell. The resulting hydrogen-rich blowdown is introduced to a vented chamber, where the entrained hydrogen combines with the precipitate to form a froth which can be separated by conventional techniques. In addition to the hydrogen, two materials present in most blowdown act as flotation promoters for the precipitate. These are (1) air, with which the blowdown water becomes saturated in the course of normal cooling-tower operation, and (2) surfactants which commonly are added to cooling-tower recirculating-water systems to inhibit the growth of certain organisms or prevent the deposition of insoluble particulates.
