Abstract:

The removal efficiency of ferrate (Fe(VI)) on endocrine disrupting compounds in secondary effluent was investigate. Biological treatment process is able to decrease estrogenic activity in wastewater to 99.6 ng E2 equivalent/L, or decreased 46.6% . After chlorination, estrogenic activity in secondary effluent is increased to 128.63 ng E2 equivalent/L, or increased 29.14%. When treat secondary effluent with ferrate, maximum EDCs deactivation efficiency of 61% were obtained. Optimum dose of ferrate at 6 ppm is able to deactivated 54.18 % of estrogenic activity from secondary effluent. The increased concentration of organic matter in secondary effluent decreases percent EDCs deactivation to 23.7 for ferrate when its concentration went up from 11 to 20mg/L of TOC.
