Filtration system

Abstract

To provide a filtration system capable of controlling, autonomously by artificial intelligence (AI), a treatment system for filtering a slurry liquid.SOLUTION: The filtration system comprises: an imaging unit positioned on a path of a fluid within a filtration system; an imaging unit acquiring image data pertaining to the fluid; an assessment unit that assesses a state of a treatment system on the basis of the image data; and an output unit that outputs a control signal to the treatment system on the basis of the result of assessing the state of the treatment system. The state of the treatment system includes a state of treatment of the filtration system, a state of degradation of a filter material, or a state of an abnormality in the filter material. The assessment unit assesses the state of treatment of the filtration system, the state of degradation of the filter material, or the state of the abnormality in the filter material by using an assessment model that is trained through machine learning to accept the image data as input data and to output the state of treatment of the filtration system, the state of degradation of the filter material, or the state of the abnormality in the filter material as output data.SELECTED DRAWING: Figure 1
