CLARIFYING DEVICE USING CENTRIFUGAL FILTER, AND CONTAMINATION-DETECTING SENSOR USING THE FILTER

摘要

PROBLEM TO BE SOLVED: To provide a clarifying device using a centrifugal filter in which clarified water having constant purity is obtained even if the quality of water to be treated is changed and clarification of water is contrived by detecting the degree of contamination of water to be treated with high accuracy. SOLUTION: The clarifying device using a centrifugal filter is equipped with a rotary cylinder 4-2 which is driven by a motor 4-1 and has drilled holes in the peripheral face, an undefined flexible filter 4-3 stuck to the inner peripheral face of the rotary cylinder 4-2 in a belt shape, a fixed cylinder 4-4 covering the outside of the rotary cylinder 4-2, a flow path leading liquid into the rotary cylinder 4-2 and the flow path leading liquid recovered into the fixed cylinder 4-4 through the holes of the filter 4-3 and the rotary cylinder 4-2. Furthermore, the contamination-detecting sensor which optically detects the degree of contamination of liquid, is provided.
