Filtered water monitoring device and filtered water monitoring system

A filtered water monitoring device for detecting damage in a filtration medium installed downstream of a membrane filtration water clarification device, thereby monitoring degradation of performance of the membrane filtration water clarification device in order to secure safety of filtered water flowing out from the membrane filtration water clarification device, the filtered water monitoring device comprising:

• a branch filtered water pipeline system which is branched, in order to collect specimen water, from a filtered water pipeline system connected to an outlet of the membrane filtration water clarification device;
• a filtered water observation plate which is installed in said branch filtered water pipeline system, and which includes an observation chamber, the filtered water observation plate being formed of two plates coated with a hydrophilic membrane and joined together face-to-face at a junction, wherein a flow passage through the filtered water observation plate is formed along the junction between the two plates, wherein the observation chamber is formed in the flow passage and at the junction between the two coated plates, and wherein opposing ends of the flow passage are respectively connected to inlet and outlet pipes of the branch filtered water pipeline system;
• imaging means for capturing an image of the filtered water flowing through said observation chamber of said filtered water observation plate, and for outputting image information based on the captured image;
• and
• image analyzing means for receiving the image information output from said imaging means, and for comparing the image information with a stored image pattern to identify impurities contained in the filtered water flowing out from said membrane filtration water clarification device.
