  • Publication number: 20230398498
    Abstract: A method of implementing membrane cleaning is provided. The method includes accessing a membrane resistance record, where the membrane resistance record includes a plurality of membrane resistance curves, each of the plurality of membrane resistance curves includes a curve profile after a cleaning. The method further includes performing a first cleaning, determining a first membrane resistance after the first cleaning, determining a current position on the curve profile based on the first membrane resistance and a time period from a previous cleaning, and performing a second cleaning. The second cleaning may include a recovery cleaning when the current position on the curve profile exceeds a predetermined range, and a maintenance cleaning when the current position on the curve profile is within the predetermined range.

  • Publication number: 20230305551
    Abstract: Methods, systems, and computer program products for automated fault monitoring and detection in a system. The fault detection method comprising receiving real-time device measurement data from a plurality of input and/or output devices in the system; identifying at least one relationship that correlates the real-time device measurement data to a set of parameters that define operation of the system; calculating a performance indicator for the system based on the real-time device measurement data using the identified at least one relationship; and if the performance indicator is outside a predetermined range, then an anomaly is detected in the system. The fault detection method further comprises: identifying a faulty device among the plurality of input and/or output devices; and reporting the identified faulty device.

  • Publication number: 20230057340
    Abstract: Methods, systems, and devices for equipment reading in a factory or plant environment are described, including: capturing an image of an environment including a measurement device; detecting a target region included in the image, the target region including at least a portion of the measurement device; determining identification information associated with the measurement device based on detecting the target region; and extracting measurement information associated with the measurement device based on detecting the target region. In some aspects, detecting the target region may include: providing the image to a machine learning network; and receiving an output from the machine learning network in response to the machine learning network processing the image based on a detection model, the output including the target region.

  • Patent number: 10496046
    Abstract: The invention enables methods, systems and computer program products for control system optimization. The invention comprises retrieving from an engineering information repository, control system engineering information corresponding to an implemented control system. Based on the retrieved control system engineering information, a plurality of function blocks and function block interconnections corresponding to the implemented control system are identified. At least one group of function blocks is identified from among the plurality of function blocks corresponding to the implemented control system. Identification of the group of function blocks is based on identification of one or more attributes shared by each function block within the identified group of function blocks. The invention thereafter generates a control system topology based on the identified function blocks, identified function block interconnections, and identified group of function blocks.
