    Abstract: A continuous resin regeneration system includes a process by which resin in need of being recharged is continuously cycled out of a filtration “column” as new resin is flowed in.

    Abstract: The disclosure provides an apparatus and method for the separation of a paramagnetic component from a mixture using a mechanical membrane apparatus. The mechanical membrane comprises a supporting material having a plurality of pores where each pore is surrounded by a plurality of magnetic regions.

In operation, a flow of fluid such as air comprising a paramagnetic component such as O2 is directed toward the mechanical membrane, and the paramagnetic component is typically attracted toward a magnetic field surrounding a pore while dimagnetic components such as N2 are generally repelled. As some portion of the fluid passes through the plurality of magnetic apertures to the opposite side of the mechanical membrane, the mechanical membrane generates a fluid enriched in the paramagnetic component.

  • Patent number: 9220999
    Abstract: An in-line filter is disclosed for filtering fluid flowing through a hydraulic system, particularly an automotive hydraulic system. The filter has a magnetic base with a central opening at its outlet and a seat with a central opening at its inlet. The base and the seat are joined by a cylindrical filter element made of a magnetically susceptible mesh screen material. A spring within the filter element biases a ball against the central opening of the seat normally sealing off the opening and forcing fluid to flow through the filter element to be filtered. If the mesh screen becomes clogged, backpressure forces the ball away from the seat against the bias of the spring to allow fluid to bypass the filter element and flow directly through the filter. Ferrous debris within the fluid flow continues to be captured by attraction to the magnetic base and the magnetized filter element.

  • Patent number: 9023200
    Abstract: A rotary-drum type magnetic separator includes a rotary drum on which a plurality of magnets are disposed, and separates an unnecessary material contained in used coolant. The magnetic separator includes a pair of partition portions that are provided below both end portions of the rotary drum and partition a flow passage, in which the used coolant flows, into a flow passage that is formed near the middle portion of the rotary drum and flow passages that are formed near both end portions of the rotary drum; and openings that are formed at lower portions of the flow passages partitioned by the partition portions. The partition portions function as filters preventing the unnecessary material from moving to the flow passages, which are formed near both end portions of the rotary drum, from the flow passage that is formed near the middle portion of the rotary drum.

  • Publication number: 20150076073
    Abstract: The current invention provides a novel process for the treatment and reclamation of drilling frac flowback and produced wastewater from the drilling industry. The wastewater is delivered to the EMC/F System from a frac tank or other reservoir. The wastewater is pumped into the system and is treated sequentially by passing through a mechanical hydrocavitation unit, an electromagnetic unit, an electrocoagulation unit and/or a hydrocyclone and a flocculation-sedimentation tank. Polishing of the final effluent is accomplished by passing the water through a mixed media tank.
