Abstract
A device for the production of ultrapure water comprising tubes containing water treatment elements joined by two end plates. Grids are disposed between the tubes and the end plates to retain resin or carbon particles. Connector terminations provide a hydraulic connection between a control unit and the tubes. The filter is mounted in the tubes by means of an adapter which also provides a seal between inlet and outlet sides of the filter. Holes are provided in the connector terminations and the end plates to enable selection of the path of fluid in the water treatment elements.
