Abstract

577,449. Purifying liquids. PERMUTIT CO., Ltd. Oct. 27, 1944, Nos. 21004 and 21005. Convention date, Oct. 28, 1943. [Class 46] A device for use in the treatment of liquid, for example making seawater potable, comprises a collapsable bag 10 of pliable plastic material with an outlet 14 and an open top adapted to be closed by being folded downwards, the bag also having a filter 23 mounted in a rigid support. One half of the wall of the bag is united to a stiff strip 30 and the other half to a thinner strip 31, and the ends of the strips are untied to one another, so that by pressure at the ends the strips can diverge to allow liquid to be introduced. The outlet 14 is closed by a plug 16 before the water and heating material are put into the bag, after which the top end of the bag is folded four times over the strips 30, 31 so that it abuts against a plate 34 provided with a buckle 32, and is secured by a strip 35. The water is shaken with the treating material, left for a time and then can be used by being sucked through the tube 14. The filter 23 is supported on one side by a ribbed perforated plate 22 and on the other side by a rigid member 24. The device may be used in the treatment of sea-water with reagents as described in Specification 576,699. It may also be used in ion-exchange treatment of other liquids.
