Activated carbon adsorption of petrochemicals

Abstract

As stream quality criteria have be come increasingly s ringent, several advanced methods have been considered for more efficient treatment of wastewater. Removal of residual organic compounds from wastewater by activated carbon ad sorption is the advanced method that has received the most attention.1 Carbon treatment can be applied in a typical flow scheme for a facility treating petrochemical plant wastes at two posi tions. A tertiary treatment stage for re moving refractory organics following con ventional secondary (biological) treatment usually is visualized. However, because of the high concentration of impurities en countered in various individual waste
