ABSTRACT:
Activated carbon filtration materials are obtained by impregnating phenolic resins into inorganic porous bodies, such as ceramic filter tubes and plates, then baking the impregnated bodies to carbonize the resins. The invention also includes improved methods for purifying aqueous liquids contaminated with phenol, live bacilli, pyrogens, or water soluble organic dyes and a process for regenerating spent filters.
