  • Patent number: 9562861
    Abstract: A challenge in using recycled material in the papermaking process is the presence of hydrophobic organics with adhesive properties commonly known as “stickies.” Hydrophobic agglomerates can result in spots or defects in the final paper product or deposit on papermaking equipment resulting in poor runnability and downtime. Technologies for monitoring and controlling microstickies exist. However, a need exists for a technique to rapidly determine the size and content of macrostickies (diameter>100 microns) in recycled pulp process streams. The present invention is a device and method to perform real-time macrostickies and/or any visible hydrophobic particle analysis in an aqueous medium. Using the present invention, furnish quality can be monitored and treatment performance can be monitored and controlled. The technique is based on fluorescence image analysis to identify and count sticky particles as well as measure their size.

  • Publication number: 20140339147
    Abstract: A biocidal water purification apparatus exposes water to radiation to eliminate viable species. A housing forms a path for water to flow from an inlet to an outlet along a flow path through a treatment zone at which the water is subjected to radiation from a source of radiation, such as beta particles from strontium-90. The exposure to radiation is enhanced using a narrow water flow path lined with the source, especially on oppositely interleaved plates with triangular cross sections, spaced by about 0.25 inch to produce an elongated zigzag path traversed by the water, for example by vertical gravity feed. Additional aspects include other forms of radiation and pre- and post-treatment water treatment or filtration stages and alternatives for continuous, batch and timed-residence water flow management.

  • Patent number: 8859989
    Abstract: A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row.

  • Patent number: 8854788
    Abstract: It is expected to provide an ion generating apparatus and an ion presence determination method that can prevent the lower accuracy of the ion presence determination caused by the humidity effect. The ion generators are switched ON at the different timing, the electrical potential of the collecting electrode is measured to determine that the ion is present (or not present) when the voltage difference is larger (or smaller) than the threshold. A humidity detecting unit is arranged in a duct. The set threshold for the determination is based on the humidity of the humidity detecting unit, and the ion presence determination is not performed when the humidity is equal to or more than a predetermined humidity. When the determination representing no ion is obtained predetermined times, the warning is output for the users with a LED of a display, a buzzer of a controller or the like.

    Abstract: In some aspects, a flow cytometer system is provided that includes beam shaping optics positioned to manipulate a light beam and produce a resulting light beam that irradiates the core stream at the interrogation zone of the flow cell. The beam shaping optics include an acylindrical lens positioned to receive and focus light in a direction of a first axis orthogonal to a direction of light travel, and a cylindrical lens positioned to receive the light output from the acylindrical lens and to focus the light output from the acylindrical lens in a direction of a second axis orthogonal to the first axis and to the direction of light travel. The resulting light beam output has a flat-top shaped intensity profile along the first axis, and a Gaussian-shaped intensity profile along the second axis. Related methods of shaping a light beam at an interrogation zone of a flow cell are also provided.
