  • Patent number: 7396460
    Abstract: A filter element (8), especially for use in backwash filtering systems, includes a filtering element through which a contaminated fluid flows in at least one direction (24). An intercepting device (62) has at least one rod-shaped permanent magnet or electromagnet (64) that at least partially removes magnetizable, especially ferritic portions from the fluid, before the fluid flows through the filtering element. A detaching device (68) removes the magnetizable portions from the intercepting device (62). The detaching device (68) is configured by a stripper ring (70) that travels along the rod-shaped magnet (64) and removes the portions retained by the intercepting device (62). When the filtering element is backwashed, the stripper ring (70), moved by the fluid flow, detaches the portions retained by the intercepting device (62).

  • Publication number: 20080149549
    Abstract: A permanent magnet array iron filter has a generally circular collar made of a high magnetic permeability material with a plurality of magnetic assemblies interiorly disposed longitudinally around an interior circumference therein. Each magnetic assembly has two magnets with opposite poles facing the center of the filter and a gap between the adjacent assemblies. This arrangement intensifies the resultant magnetic field and projects the field deeply within the interior region of the filter. Rare earth permanent magnets are used to maximize the magnetic field. The collar may be coated with a plastic coating to protect the filter. The collar has a gap to provide flexibility when sliding the filter over an oil filter. The thickness of the collar may be adjusted to meet the requirements of a particular application.

  • Publication number: 20080135491
    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.
