Abstract

1516825 Purifying water CREUSOT-LOIRE 20 April 1977 [30 April 1976] 16440/77 Heading C1C Water containing both hydrocarbons and detergents is treated to remove the hydrocarbons by adding liquid hydrocarbons to increase the hydrocarbon content to 0À1-5% by weight to give a weight ratio of hydrocarbon to detergent of between 1:1 and 10:1 and then passing the mixture through a column containing an oleophic packing material which adsorbs the hydrocarbons.
