Poliovirus removal from primary and secondary sewage effluent by soil filtration

Abstract

Adsorption of poliovirus from primary sewage effluent was similar to that from secondary sewage effluent in both batch soil studies and experiments with soil columns 240 cm long. Virus desorption by distilled water was also similar in a soil column that had been flooded with either primary or secondary effluent seeded with virus. These results indicated that adsorption of poliovirus from primary effluent and virus movement through the soil were not affected by the higher organic content of primary sewage effluent.
