Abstract:
1. A filtrate water monitoring apparatus which monitors filtrate water discharged from a membrane filtration water-purifying apparatus, comprising: physical detection means for utilizing or detecting a physical phenomenon which varies depending on behavior of particles in the filtrate water flowing in a branch filtrate water pipe line system (hereinafter, called “particles in flowing water”) wherein the physical detection means is connected to the branch filtrate water pipe line system branching in order to sample some of the filtrate water as sample water from a filtrate water pipe line system connected to an outlet of the membrane filtration water-purifying apparatus; a filtrate water observation cell which is arranged downstream of the physical detection means in the branch filtrate water pipe line system and has a flow channel for letting the filtrate water pass through inside thereof; and image detection means for shooting an image in filtrate water flowing in the flow channel of the filtrate water observation cell and for identifying impurities included in the filtrate water.
