Device for measuring load loss in reverse osmosis membrane containers

Device for measuring load loss in reverse osmosis membrane containers, which use is applicable in sea water or otherwise salty water desalination facilities, that use a plurality of permeable membranes assembled inside a pressure container (1) fed by the water to be treated through one of its ends (5), said membranes being correlatively connected together by means of a permeate water collection tube (3), comprising an interconnector (7) placed between two consecutive membranes that serves to establish two membrane groups (2) and (2′) on either side of said connector (7) housed inside the pressure container (1), and characterized in that the interconnector (7) coupled to the permeate water tube (3) to establish the two groups of membranes (2) and (2′), presents one open end (8) and a closed opposite end (9), it also presents a peripheral area at approximately halfway of said interconnector (7) enclosing a plurality of orifices (10) arranged circumferentially and through which communication is established with an axial chamber (11) determined in the interconnector (7) itself, oriented towards its open end (8) at which there is a coupling nut (12) that connects it to a small diameter pressure tube (13) that runs along within the permeate water collection tube (3) located between the interconnector (7) and the water to be treated feed inlet (5);

• which pressure tube (13) still elongating outside the pressure container (1) after crossing through the closing lid (4) capping the end of said pressure container (1);
• and having the particularity that said pressure tube (13) ends in a “T-shaped” connection (15) outfitted with a sensor (16) for measuring the pressure of the non-treated reject water corresponding to the group of membranes (2) established between the feed end (5) that lets in the water to be treated and the interconnector's (7) assemble point (17).
