SPIRAL-TYPE FILM MODULE, AND FILM FILTERING DEVICE USING THE SAME

摘要

Provided are a spiral-type film module capable of deciding the degree of deterioration for each film element by a simple method, and a film filtering device using the film module. In the spiral-type film module (50), spiral-type film elements (10) each having one or more of a separating film, a feeding-side passage member and a transmitting-side passage member wound around a porous, hollow center tube are connected in plurality and fitted in a pressure container. The spiral-type film module (50) is characterized by comprising a pressure sensor (33) for detecting a pressure level to be applied to the outer circumference portion of each of the spiral-type film elements (10), and a wireless tag (30) for transmitting the pressure level detected by the pressure sensor (33).
