Patent ID: 7886582

Claim:
A DEVICE FOR MEASURING LOAD LOSS IN REVERSE OSMOSIS MEMBRANE CONTAINERS, being applicable in sea water or salty water desalination facilities and comprising a plurality of permeable membranes assembled inside a pressure container feeding the water to be treated through a feed inlet end, said membranes being correlatively connected together by a permeate water collection tube, the device further comprising an interconnector placed between two consecutive membranes of the plurality of membranes that serve to establish a first and a second groups of membranes on either side of said interconnector housed inside the pressure container, and wherein the interconnector is coupled to the permeate water collection tube establishing the first and the second group of membranes and presents an open end and a closed opposite end, as well as a plurality of orifices arranged circumferentially and located at a peripheral area corresponding to an approximately intermediate section of said interconnector, wherein said plurality of orifices establish a connection with an axial chamber comprised in the interconnector and oriented towards the open end of the interconnector, said open end comprising a coupling nut that connects the interconnector to a small diameter pressure tube that runs along the inside of a first section of the permeate water collection tube located between the interconnector and the feed inlet end; said pressure tube extending outside the pressure container after passing through a closing cap of an end of said pressure container and ending in a T-shaped connection comprising a sensor for measuring the pressure of non-treated reject water corresponding to the first group of membranes located between the feed inlet end and an assembly point of the interconnector.
