Abstract

1,200,364. Removal of suspended solids from liquid. SOC. D'ETUDES POUR LE TRAITEMENT ET L'UTILISATION DES EAUX. 22 Aug., 1967 [28 Sept., 1966], No. 38706/67. Heading ClC. Liquids containing suspended solids are passed upwardly through a fluidized bed of granular material at such a speed that the granular material and suspended solids are not entrained and purified liquid is decanted from the top.
