The effect of pH and soluble organic matter on virus adsorption to activated carbon in treated sewage was determined. Poliovirus removal from wastewater effluent was greatly improved by lowering the pH to 3.5-4.5 or by reducing the amount of organics by lime coagulation. Batch studies indicated that virus adsorption to activated carbon in wastewater could be described by Freundlich isotherms. In column experiments virus removal was found to be dependent on column length as well as hydraulic loading. Virus and soluble organics adsorbed at low pH could become deadsorbed by a rise in pH.
