Abstract: PROBLEM TO BE SOLVED: To enable continuous measurement of the degree of turbidity by sampling both unfiltered water and washing drainage and measuring turgidity and chromaticity. SOLUTION: A turbidity meter 12 is provided on the inflow side of unfiltered water in a filter basin 11. The turbidity meter 12 performs water sampling of unfiltered inflow water and washing drainage through a three-way valve 13 and turbidity and chromaticity are measured.

Further, in measurement of washing drainage, washing start of the filter basin 11 is detected by a level gage or the like not shown in the figure. Drainage of the latter half of the interval of water washing is sampled via the three-way valve 13. The washing state at this time is measured by the turbidity meter 12 and the dirty state of the filter basin is judged.  A high-sensitivity turbidity meter 14 is provided on the outflow side of filtered water sent from the filter basin 11. Change in turbidity after washing of the filter basin 11 is measured by continuous measurement of filtered water with the high-sensitivity turbidity meter 14. A continuous state of turbidity, in which change in turbidity is <=0.1 degree, is measured and optimum water passing time or the like are judged.
