    Abstract: A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.

  • Patent number: 7429331
    Abstract: The present invention provides an apparatus for inducing magnetism in a flowstream of an at least partially magnetizable particulate feed material suspended in a liquid, the apparatus including: a treatment chamber having an inlet and an outlet through which the flowstream respectively enters and exits the chamber; and a magnetic source able to be selectively activated with respect to the treatment chamber, such that, when activated, the magnetic source induces magnetism in at least some of the particulate feed material located in the chamber. This allows the introduction of a high gradient magnetic field to effectively magnetize both the weakly and strongly magnetic particulates for subsequent removal by setting or other techniques. When the magnetic source is deactivated, the flow stream of feed material dissipates the deposits of magnetized material from around the source to reduce the possibility of any flow restrictions and maintain the effectiveness of magnets.

  • Patent number: 7410573
    Abstract: A waste water purification system for purifying polluted salt water including oil and the like by coagulating and separating pollutant matter in the polluted salt water can regenerate and reuse a coagulant in the system while scarcely resupplying the coagulant, an acid solution and an alkaline solution. The acid and alkaline solutions are required for disintegrating coagulated flocs from the polluted salt water and regenerating the coagulant from sludge. Alkaline water enriched in sodium hydroxide and an acidic aqueous solution containing hydrochloric acid and the like are generated by electrolyzing the purified salt water. The flocs in the separated sludge are disintegrated by use of the alkaline water, pollutant matter is removed from the disintegrated aqueous solution, and the strong acidic containing the hydrochloric acid is added to the aqueous solution removed of the pollutant matter to have the coagulant. The coagulant can be thus regenerated from the recovered sludge.

    Abstract: A two-step chemical precipitation process involving hydroxide precipitation and sulfide precipitation combined with “field separation” technology such as magnetic separation, dissolved air flotation, vortex separation, or expanded plastics flotation, effectively removes chelated and non-chelated heavy metal precipitates and other fine particles from water. In the first-step, the non-chelated heavy metals are precipitated as hydroxides and removed from the water by a conventional liquid/solids separator such as an inclined plate clarifier to remove a large percentage of the dissolved heavy metals. The cleaned water is then treated in a second precipitation step to remove the residual heavy metals to meet discharge limits. In the second precipitation step, any metal precipitant more effective than hydroxide for metal precipitation can be used.

  • Patent number: 7241383
    Abstract: A fluid treatment method includes the steps of forming a ring lamination by laminating a plurality of filtering rings with contact surfaces facing each other in a laminating direction; providing at least portions of the filtering rings with a contact surface roughness (Ra) in a range of about 0.01 ?m to 20 ?m; pressing the ring lamination under a contact surface pressure (p) within a range from 0 to 177 kg/cm2 in the laminating direction of the filtering rings to cause the contact surfaces to closely adhere to each other; directing an object fluid into gaps formed by contact surfaces of neighboring filtering rings of the ring lamination; and dividing the object fluid into a first separated fraction and a second separated fraction for separation. An apparatus for carrying out the method includes a ring lamination, a housing therefor, a ring press for acting on the ring lamination under a prescribed pressure, an object fluid source, and a pressure source for impressing a prescribed pressure on the object fluid.

  • Patent number: 7192520
    Abstract: A magnetic device for attachment on an exterior wall of a canister where the canister is mounted within a liquid flow path. The purpose of the device is to attract ferrous particulate matter flowing within the flow path and cause that ferrous particulate matter to be fixed to the inside surface of the canister therefore no longer flowing in the flow path. The device has a frame which includes a cavity and within that cavity is mounted a baseplate. Mounted on the baseplate are a pair of blocks. Mounted on each of the blocks is a plurality of magnets with the magnets mounted in a side abutting relationship in conjunction with each block. Between the blocks is located a bridge. The bridge permits limited flexing of the frame so the frame can be used to accommodate to different diameters of canisters within about a one-half inch range.

  • Patent number: 7182861
    Abstract: A method for use in two-components electrostatic image developers is disclosed, in which secure separation of a carrier coating resinous materials from a core magnetic material is achieved without affecting the properties of the core materials through process steps benign to the environment in super- or sub-critical water compositions under the conditions of a temperature of 300° C. or more and a pressure of 20 MPa. The core magnetic material is subsequently recycled for forming carrier. This method may also be useful for processing waste including magnetic materials with silicone resin coating.

  • Patent number: 7160469
    Abstract: Many areas in the world already suffer shortages of water, and others will suffer from it in the coming years. Therefore more efficient water sweetening is essential for our survival on this planet. The most commonly used water sweetening methods are: Reversed osmosis, distillation, electrodyalisis, and partial freezing. However, these methods suffer from low efficiency and high energy consumption, thus making them significantly more expensive than naturally obtained water. The present invention describes a system & method for efficient and low energy sweetening of water, based on borderline fast fluctuation between liquid to gaseous state and back, by using centrifugal forces to make water droplets fly at a high speed, so that they evaporate for a split second, the salt is separated, and they condense again. The present invention tries to make the process energy-efficient by enabling the use of lower speeds and smaller droplet sizes and solving various problems involved with that.

  • Patent number: 7083718
    Abstract: A water boiler system for producing steam or hot water includes an apparatus for removing dissolved minerals from the boiler water without the use of water softeners or other chemical treatment agents. An electromagnetic flux producing device first treats water of the boiler system with alternating electromagnetic flux to cause nucleation of dissolved minerals in the bulk boiler water, rather than on boiler surfaces, with nucleated particles then accumulating into particulates which settle by gravity to a low area of the boiler. Water is continuously drained from the low area of the boiler and fed by a pump to a mechanical separator which continuously separates solids from the drain water and continuously passes cleansed water at a high temperature back to the boiler.

  • Patent number: 7077954
    Abstract: An apparatus and method for recirculating machine tool coolant in which coolant and entrained debris flowing in a shallow stream trough are raised to a higher level by rotation of a bladed wheel in a housing arranged to receive the liquid flow stream. Coolant and debris is then directed down at a magnetized body in a plunging discharge to bring ferrous debris into contact with an upwardly facing surface of the magnetized body. The coolant and nonferrous remaining entrained debris is collected in a tank and pumped back to the filter apparatus by a chopper pump which has a hardened impeller having cutting edges cutting up the remaining debris as it is pumped by the impeller.
