Abstract (en)

[origin: WO9913958A1] A fluid treatment arrangement includes a tube sheet (30) and a plurality of fluid treatment elements (60) sealed to the tube sheet (30). The fluid treatment arrangement is designed so that the fluid treatment elements (60) can be easily unsealed and removed from the tube sheet (30). According to one form of the invention, the arrangement includes an ejector mechanism (90) movable with respect to the tube sheet (30) into and out of contact with the fluid treatment elements (60). When the ejector mechanism (90) contacts the fluid treatment elements (60), it exerts an axial force on the fluid treatment elements to produce relative movement between the fluid treatment elements (60) and the tube sheet (30) by a sufficient distance to unseal the fluid treatment elements (60) from the tube sheet (30), making it easy to remove the fluid treatment elements from the tube sheet. In preferred embodiments, the fluid treatment elements comprise filter elements.
