Device for measuring head loss in reverse osmosis membrane containers

摘要

The invention relates to a device for measuring head loss in seawater reverseosmosis membrane containers. More specifically, the invention relates to areverse osmosis unit (1) with two groups (2 and 2') of membranes, throughwhich a water permeation tube (3) extends. The reverse osmosis unit includesan interconnector (7) coupled to the tube (3) that separates the two groups (2and 2') of membranes. The interconnector (7) includes an open end (8) anda closed end (9) and a zone provided with holes (10) communicated with an axialchamber (11). Said open end (8) is provided with a connector (12) for a pressuretube (13) which extends through the tube segment (3) corresponding to the groupof membranes (2), emerging externally from the cover (4) sealing the supply end(5) of the pressure tube (1) and extending to a connection (15) that has been providedwith a pressure meter (16) that can be used to measure the pressure at the point(17) at which the interconnector (7) is mounted.
