Abstract
1287759 Filter for water A FOURCADE 29 Sept 1969 [4 Oct 1968] 47833/69 Heading B1D A filter for swimming pool-water comprises an upright cylindrical casing with a lower tangential inlet (3) whereby water enters an annular gap 6 between the casing and the outer cylindrical walls of elementary filters 5, each comprising a central sleeve 7, a base 12, perforate support 13 and anular bed 15 of sand or active carbon, which could be replaced by a bag of kiesulguhr or a porous coherent filtering body. Water enters filters 5 by punched apertures 16 and leaves by apertures 14 in sleeves 7, which are shaped to stack vertically forming a vertical filtrate duct leading to lower outlet (4). Beds 15 are shielded by frustoconical baffles 17 and by the flaps formed when apertures 16 are punched inwards. Rings 10 seal the filters 5 together where sleeves 7 engage, and filters 5 may be unstacked after removing the upper part of the casing, enabling sand beds to be replaced by porous bodies &c., or vice versa.
