    Abstract: A composition, a system and a method for making the composition and a system and a method for using the composition are provided. The composition, the system and the method for making the composition and the system and the method for using the composition are used to passively treat a solution. The composition is a mixture of a catalyst-altered water, a colloidal solution and a treated water. The composition is produced by mixing the catalyst-altered water, the colloidal solution and the treated water at room temperature. The composition, the system and the method for making the composition and the system and the method for using the composition have a sphere and/or a tube for housing the composition in an internal compartment of the sphere and/or the tube. Exposure of the solution to the composition and/or to an exterior surface of the sphere and/or the tube containing the composition raises a pH and/or an alkalinity of the solution and/or changes a structure of the solution.

  • Publication number: 20080210636
    Abstract: A fluid filter comprises a filter housing, having an inlet end (202) and an outlet end (204), and a plurality of bundles of fibres (211) extending longitudinally of the housing and being secured at the inlet end. The fibres are charged with an electric or magnetic field to selectively block or allow the passage of particles of a known charge present in the fluid through to the outlet end. To flush the filtered particles out of the filter, the charge imparted to the fibres is reversible to allow the charged particles to flow freely through the filter. The filter can also be used to control the settling characteristics of particles in a fluid.

  • Publication number: 20080011683
    Abstract: A system and method to remove a polluting agent or contaminant, including but not limited to mercury, from the liquid phase of a process system using an adsorbent. In one exemplary embodiment, a magnetic or non-magnetic support with a chemisorbing or physisorbing sorbent is suspended in the liquid phase of a process system, under conditions in which the polluting agent binds to the adsorbent. The pollutant-bearing adsorbent may then be separated from the process system by either physical or magnetic means. The polluting agent may then disassociated from the adsorbent so the adsorbent is regenerated and capable of repeated use.

  • Patent number: 7314552
    Abstract: The method for separating ferrate salts from a solution comprising providing contact between the solution of essentially of aqueous hydroxide and the ferrate salts and a surface having a magnetic attraction, magnetically securing the ferrate salts to the surface; and eliminating contact between the solution and the surface. Contact is provided by immersing the surface in the solution, passing the liquid ferrate mixture over the surface, or combinations thereof. The magnetic attraction may be induced by permanent magnets, electromagnets, and combinations thereof. The apparatus for ferrate production comprises an electrochemical cell having an iron-containing anode, cathode, and an aqueous hydroxide solution in fluid communication with both the anode and the cathode, and a magnetic separator in fluid communication with the aqueous hydroxide solution for separating ferrate salts from the aqueous hydroxide solution.

  • Patent number: 7311846
    Abstract: A method and apparatus for separating ferrous metal particles from non-ferrous metal particles suspended in a liquid, such as a coolant from a machining operation, in which mixed particle containing liquid is discharged across a horizontal, non-magnetic separating surface; the magnetic ferrous metal particles are captured by a magnetic force exerted by an array of parallel magnets disposed underneath the separating surface, the non-magnetic non-ferrous metal particles are washed by the liquid into a collecting flume from where they can be passed to a filtering station for removal from the liquid, and the captured ferrous metal particles are scraped from the separating surface and conveyed to a ferrous metal discharge by a scraper conveyor which moves transversely to the discharge direction of the liquid.

  • Patent number: 7309439
    Abstract: A device for transporting magnetic or magnetizable microbeads (25) in a capillary chamber (14) comprises a permanent magnet (10) or an electromagnet (11) for subjecting the capillary chamber to a substantially uniform magnetic field, to apply a permanent magnetic moment to the microbeads (25). At least one planar coil (22) and preferably an array of overlapping coils are located adjacent to the capillary chamber (14) for applying a complementary magnetic field on the microbeads parallel or antiparallel to said substantially uniform magnetic field, to drive the microbeads. An arrangement is provided for switching the current applied to the coil(s) (22) to invert the field produced thereby, to selectively apply an attractive or repulsive driving force on the microbeads (25). The device is usable to transport microbeads for performing chemical and biochemical reactions or assay, as is done for instance in clinical chemistry assays for medical diagnostic purposes.

  • Patent number: 7288185
    Abstract: A magnetic energy wave device has a winding spiral pipe, a magnetic conductive metal layer, a hollow coil holder, and a circuit board. A magnetic switch is assembled at a water inlet of the winding spiral pipe. The magnetic conductive metal layer is sleeved outside the winding spiral pipe. The winding spiral pipe and the magnetic conductive metal layer are assembled in the hollow coil holder. A coil is wound around the hollow coil holder. The circuit board is connected to an external power source, and is electrically connected to the magnetic switch and the coil. When water passes through the water inlet, the magnetic switch connects the power source and the coil. The coil and the magnetic conductive metal layer therefore produce dynamic magnetic fields to magnetize fully water in the pipe.
