Abstract

In this article, the removal of surfactant by ozone and BAC was studied. Batch and pilot tests were carried out for these studies. In batch tests, efficiency of ozone oxidation process was evaluated for LAS(Linear Alkylbenzen Sulfonate) and SLS(Sodium Lauryl Sulfate) removal. Under oxidant conditions, the removal of LAS was more effective than that of SLS. The removal of surfactant was more enhanced with increasing pH in oxidant systems. Pilot tests are carried out with BAC single process and ozone oxidation/BAC combined process. The removal of LAS was more effective in ozone oxidation/BAC combined process than BAC single process about 10-20%. In the case of SLS, the efficiency of BAC single process was similar to that of ozone oxidation BAC combined process. According to temperature, the removal efficiency of SLS changed from 70% to 95% and initial concentration of surfactant had no effects on removal efficiency of SLC under applied temperature above $15^{\circ}C$.
