Abstract

The ability of a typical soil to remove nonionic surfactants from wastewater was investigated. A packed bed using the above soil, with suction filtering of Polyoxyethylenenonylphenylether (NP10,15,20) solution through the packed bed, was prepared. We found that the removal efficiency decreased as the concentration of the NP10 solution is increased and that the Freundlich equation could be used to describe the relationship between the concentration and the removal efficiency in the concentration range of 20-200 ppm. In addition, the removal efficiency tended to decrease as the mole number of added ethyleneoxide (EO) units is increased. This method was found to have a high removal efficiency with regard to wastewater including these solutions of such low concentration that would be discharged into the environment.
