Title:
TRANSMEMBRANE PRESSURE DIFFERENCE INFERENCE DEVICE AND DIFFUSED AIR AMOUNT CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/138189
Kind Code:
A1
Abstract:
The present invention appropriately infers the change over time of transmembrane pressure difference, in order to carry out an appropriate membrane filtration operation, without being limited to typical approaches to diffused air amount control. An inference device (2) comprises: an input data acquisition unit (21) that acquires input data derived from operation data including membrane filtration pressure and a diffused air amount which are measured during a membrane filtration operation; and an inference unit (23) that uses a regression model (31) to infer transmembrane pressure difference related data for a time after a predetermined time period, that carries out M times (where M is an integer of 2 or more) a process, in which the input data is rewritten N times (where N is an integer of 2 or more) by changing the transmembrane pressure difference related data included in the input data to the inferred transmembrane pressure difference related data, while altering a part of data included in the input data, and that consequently obtains M inference results for the change over time of transmembrane pressure difference up to after the predetermined time period multiplied by N.
