Loading and unloading arrangement for desalination membrane modules in vertically arranged pressure vessels

摘要

An anchoring arrangement for suspension of a membrane having a main conduit of a diameter d, said anchoring arrangement comprising a central line with circumferential suspenders arranged therealong, wherein each of said suspenders is adapted to assume a first, retracted position in which the radial extension of each suspender about said line is of a diameter d1<d, to allow insertion of the anchoring arrangement into said conduit in said retracted position, and a second, deployed position in which the radial extension of each suspender about said line is of a diameter d2>d, to allow engagement between the suspenders and the central conduit's surface in said deployed position thereof.
