Abstract

1322602 Portable ion-exchange apparatus A GOTTENBUSCH and H TAFEL 10 Sept 1970 43321/70 Heading B1J [Also in Divisions C1 and F2] Portable water-treatment apparatus comprises a housing having a number of chambers containing different reagents, a water inlet 8, a water outlet 9 and a selector valve 50 by which water from the inlet may be directed through different ones of the chambers, and preferably in different orders, to the outlet so as to be subjected to different treatments. As shown, interconnected chambers 10 contain ion-exchange material for softening the water, interconnected chambers 11 contain an absorbent (activated carbon) and interconnected chambers 12, provided with a screw cap 16, contain salt for regenerating the ion-exchange material. The valve shown in Fig. 1 is actuated by press-buttons and provides for direct passage from inlet to outlet; for passage through the ion-exchange material only; for passage through the absorbent only; for passage through bath; and for passage through the salt and ion-exchange material for regeneration of the latter. In a modification (diagrammatically represented in Figs. 10A and B, not shown), the salt chamber is emptied except for regeneration and water is normally passed through the ion-exchange and salt chambers in the opposite direction to that used in regeneration. The valve 50 may be replaced by a slide valve or rotary selector valve. The housing is formed in two parts 1, 2 and a grooved conduit plate 3, Fig. 4 (not shown), interconnects the valve passages with the chambers in the upper part 2, and through a passage in that part, to those in the lower part 1. The reagents may be contained in plastic containers 53, Figs. 19-26 (not shown), shaped to fit the chambers and having perforated portions to correspond with the openings into and between the chambers, and central sealing rings.
