FILTRATE MONITORING DEVICE, AND FILTRATE MONITORING SYSTEM

摘要

Provided are a filtrate monitoring device and a filtrate monitoring system, which can monitor a membrane-type water filtrating/purifying system at all times and which can match the contents and sizes of impurities softly. The filtrate monitoring device monitors the filtrate having emanated from a membrane-type water filtrating/purifying device. The filtrate monitoring device is characterized by comprising imaging/detecting means for imaging the filtrate having emanated the filtrating/purifying device, on the filtrate flowing in an observation bath of a filtrate observing cell disposed midway of the branched filtrate pipeline, thereby to specify the particles contained in the filtrate, and/or optical detecting means disposed midway of the filtrate pipeline before or after branched.
