Abstract

Oily contaminants are removed from aqueous liquids by contacting the liquid with a carbon based adsorbent material to form a layer of the oil contaminant on each particle. The particles are then electrochemically regenerated, and then recycled in contact with the liquid to form an additional layer of the oil contaminant on each particle. The adsorbent is not fully regenerated between cycles, but can be eventually fully regenerated by electrochemical oxidation.
