Abstract: The process uses clusters of 5-35 wt.% Fe3O4 and 95-65 wt.% powdered activated C, that is removable by a magnetic filter, to remove insecticides, detergents, phenols, dyes, enzymes, viruses, fats, proteins, polysaccharides, oil, colloids or colour-or odour- producing organic compounds from water, for the tertiary treatment of sewage or for removing colour impurities from organic resins, dry cleaning agents and colour and odours from glycerine. Lower costs and greater speeds than using activated C opt. mixed with a flocculating agent and/or weighting agents (magnetite or clay).

Abstract: A process for the removal of organic contaminants from a fluid stream containing organic contaminants. The process involves dispersing a magnetically susceptible iron-carbon complex in the fluid stream, maintaining the magnetically susceptible ironcarbon complex in a dispersed condition until a substantial amount of contaminants have been adsorbed from the fluid stream, and passing the magnetically susceptible iron-carbon complex containing dispersion through a magnetic filter to separate the dispersion into a fluid stream having a reduced concentration of contaminants and an adsorbed complex containing contaminants. Regeneration of the adsorbed complex may be accomplished by heating the complex in an inert atmosphere at a temperature sufficient to desorb and vaporize the contaminants.
