Title:
ELECTRONIC DEVICE FOR CONTROLLING HOLLOW-FIBER MEMBRANE FOULING REDUCTION SYSTEM, SYSTEM COMPRISING SAME, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/128072
Kind Code:
A1
Abstract:
According to one aspect of the present disclosure, an electronic device for controlling a hollow-fiber membrane fouling reduction system comprises: an exciter controller for generating an excitation signal; an exciter module electrically connected to the exciter controller so as to generate vibration corresponding to the excitation signal; and a hollow-fiber membrane module for receiving the vibration generated by the exciter module, and comprises: a vibration analysis module for receiving a first vibration value and a second vibration value that are each sensed by the exciter module and the hollow-fiber membrane module for respective frequencies, calculating a vibration transfer rate for respective frequencies on the basis of the first vibration value and the second vibration value, and calculating the optimal frequency at which the vibration transfer rate is the greatest; and an optimal sound source selection module for receiving feedback of the optimal frequency, and selecting, on the basis of the optimal frequency, an optimal sound source to be used for generation of the excitation signal from among one or more sound sources.
