20120258547 | METHOD OF MONITORING MACROSTICKIES IN A RECYCLING AND PAPER OR TISSUE MAKING PROCESS INVOLVING RECYCLED PULP - 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. | 10-11-2012 |
20130020041 | METHOD AND ARRANGEMENT FOR FEEDING CHEMICALS INTO A PULP PROCESS STREAM - An apparatus for feeding one or more chemicals into a process stream of a pulp process is disclosed, as well as a method of utilizing the apparatus for feeding one or more chemicals into a pulp process is disclosed. | 01-24-2013 |
20130078730 | METHOD FOR MONITORING AND CONTROL OF A WASTEWATER PROCESS STREAM - The invention is directed towards methods, compositions, and apparatus for accurately detecting the presence and amounts of contaminants in wastewater. The method comprises the steps of adding to a volume of wastewater at least one tracer molecule, observing the tracer for indications of particular contaminants, conducting at least one second form of contamination detection, and interrelating the two measured properties to identify the specific composition of the contamination. Using a tracer molecule allows for the detection of otherwise hard to detect oils and grease. Use of the second method however compensates for tracer interfering contaminants and allows for more accurate readings. The invention includes feeding of functional chemicals in response to the detections and conducting the detections online and continuously. | 03-28-2013 |

The method comprises operating ultrasound technology that is submerged or partially submerged into a liquid medium that is responsible for the fouling. The device comprises the ultrasound technology itself. The ultrasound technology may be operated intermittently at high intensity to advantageously provide cavitation of the liquid medium, while avoiding the disadvantages typical of continuously operating ultrasound technology at high intensity. Additionally, the method may be carried out by taking advantage of the piezoelectric property of quartz. | 07-25-2013 |
20150029496 | METHOD OF DEPOSITION MONITORING - The invention provides methods and compositions for measuring the formation of scale within a process system. The method involves measuring changes in the cell fouling as reflected on the refraction index measurements of a liquid medium with a refractometer and determining the scale formation from changes in the cell fouling factor. This allows for a refractometer to determine the formation of scale in locations that otherwise would not be measureable. | 01-29-2015 |
