Patent number: 9701955Abstract: A system having improved trapping force for acoustophoresis is described where the trapping force is improved by manipulation of the frequency of the ultrasonic transducer. The transducer includes a ceramic crystal. The crystal may be directly exposed to fluid flow. The crystal may be air backed, resulting in a higher Q factor.Type: GrantFiled: October 4, 2016Date of Patent: July 11, 2017Assignee: FloDesign Sonics, Inc.Inventors: Bart Lipkens, Jason Dionne, Walter M. Presz, Jr., Thomas J. Kennedy, III

Patent number: 9533241Abstract: Devices for separating materials from a host fluid are disclosed. The devices include an acoustic chamber having an inlet and an outlet. An ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave in the acoustic chamber that traps the materials and permits a continuous separation of the materials from the host fluid. The materials and the host fluid can thus be separately collected. Multiple sets of trapping lines are generated by the acoustic standing wave, and the transducer is oriented to minimize cross-sectional area for straight vertical channels between the trapping lines.Type: GrantFiled: March 24, 2016Date of Patent: January 3, 2017Assignee: FloDesign Sonics, Inc.Inventors: Walter M. Presz, Jr., Kedar Chitale, Bart Lipkens

Patent number: 9375662Abstract: A suspension processing method using ultrasonic waves has problems in that movement of solids in liquid do not follow movement of the sound field. Accordingly, application to a field that requires a high suspension processing performance or a high flow rate process is difficult. In order to achieve the high suspension processing performance, a design of adopting a long and large oscillator and the like is required. A suspension processing device (30) of separating and concentrating a component of solids in suspension (1a) using ultrasonic waves, includes: at least one supply port (32) for supplying the suspension (1a) into the device; a channel (31) through which the suspension flows; at least two outlet ports (33 and 34) for discharging processed suspension (1a); an oscillator (35) for emitting ultrasonic waves; and a reflection plate (36) for reflecting the emitted ultrasonic waves.Type: GrantFiled: August 7, 2013Date of Patent: June 28, 2016Assignees: Hitachi, Ltd., Tokyo Institute of TechnologyInventors: Takuya Kambayashi, Kentaro Nakamura

Patent number: 9095790Abstract: An apparatus and method for separating water from an oil-and-water mixture includes at least two elongated separator vessels oriented at an incline and connected to one another so that an upwardly flowing oil predominant fluid passes from the first separator vessel to the second separator vessel where further electrostatic separation of water from the oil predominant fluid occurs. Each vessel has an electrode at its upper end preferably connected to a different voltage source. The inlet to each vessel is located relative to the electrode to provide an up flow or a down flow vessel. Additionally, the first vessel may be at a different elevation than the second vessel. An additional vessel may be included with output from the first vessel bypassing the additional vessel, the second vessel, or both. Baffles may be added in the water collection portion of each vessel to reduce turbulence and settling distance.Type: GrantFiled: June 8, 2012Date of Patent: August 4, 2015Assignee: Cameron International CorporationInventors: Gary W.
