SEPARATION MEMBRANE MODULE

摘要

Provided is a separation membrane module including: a tubular pressure container 7 in which a raw liquid is filtered through a separation membrane to produce a permeate liquid; and an internal member 5A provided in the pressure container 7. The internal member 5A is equipped with a sensor for detecting characteristics of at least one of the raw liquid and the permeate liquid. A detected signal generated by the sensor is transmitted from an antenna 65. The internal member 5A has an antenna holding portion 54 in which the antenna 65 is embedded. A gap between the antenna holding portion 54 and an inner peripheral surface 7a of the pressure container 7 is sealed with a sealing member 42.
