ABSTRACT:
An improved header block for tubular membrane permeator modules, which has particular advantage for ultrafiltration operations, is disclosed. The header block is very compact and is formable by casting or molding and machining. In cooperation with a collector plate and end-plate, it provides both feed (or concentrate) and permeate manifolds. The high pressure differentials and/or cumbersome "turn arounds" or manifolds heretofore used are obviated by said block. A plurality of modules comprising such blocks may be joined side-by-side, in cooperation with appropriate side-plate and gasket means, to provide a variety of flow distributions and/or modes. The header block is uniquely appropriate for handling high volume flow rates required to ensure turbulent, high velocity flow of feed liquid within each permeator tube. The end plates preferably are transparent, to permit facile inspection of the permeate stream from each tube in each module.
