ABSTRACT:
An improved multi-tubular module is provided for use in ultrafiltration and reverse osmosis devices. Improved mechanical strength is achieved in the module by bonding the individual tubes to each other at spaced intervals along their total length whereby lateral and axial movement of individual tubes with respect to one another is eliminated, resulting in a coherent monolith of tubes. Additionally, improved resistance to thermal cycling is imparted to the module by connecting the tube sheet or header to the module shell in a manner which allows for slight movement of the tube sheet with respect to the module shell and yet provides a device which can be easily sanitized or sterilized when used for food or drug applications.
